Tracking & Analytics

Every ad platform tells you how many people saw and clicked your ad. None of them knows how many cars came into the shop or how much those customers paid. Tracking connects those two worlds, so you can see which money brought customers and which money only brought clicks.

For a repair shop the real result is a paid job: an iş emri (work order) that ends with a fatura (invoice). Calls, WhatsApp chats, form fills and direction requests are steps on the way. They are useful signals, but they are not money yet.

The chain from ad to money

Each paying customer moves through the same chain of steps:

Impression → click or visit → lead action (call, WhatsApp, form, directions) → booked appointment → car in the shop → invoice paid → repeat visits

Ad platforms and Google Analytics see the left part of this chain. Only you see the right part: which jobs were done and what was paid. Good tracking joins the two halves, usually with a simple customer log that the front desk fills in.

From goal to tracked actions

Write the plan before you install any tool. It takes one to two hours on paper or in a Google Sheet.

1. Write the business goal

   One sentence with a number and a date. "More customers" is too vague to measure.

2. Pick 3–5 KPIs

   For example: new paying customers per month, cost per new customer, revenue from new customers, lead-to-job rate, cost per lead by channel.

3. List every way a customer can reach you

   Phone, WhatsApp, website form, online booking, Google Maps, walking in. Next to each, write how it will be counted and by which tool.

4. Fix the names

   Decide how you will name links, events and conversions (Sections 03–06), and never mix spellings.

5. Name the owners

   Who fills in the customer log (usually the front desk, danışma), and who reads the numbers every Monday.

6. Date the plan

   Give it a version number and update it when you add a channel.

The conversions of a repair shop

List every way a customer can reach Örnek Oto Servis, and how each one is counted:

Macro, primary and micro conversions

Not every action is worth the same. Sort them into three groups:

A simple rule: tell ad platforms to optimise for the closest action to money that you can measure reliably and often enough. A beginner usually starts with form leads, call taps and WhatsApp taps. Once enough jobs are logged, you can send "job completed" data back to the platforms.

Own your accounts

Every number in this guide lives inside an account: Google Ads, GA4, Tag Manager, Business Profile, Meta. If an agency or a freelancer creates these accounts in its own name and you part ways, you can lose years of data, your conversion setup and your ad history. Set one rule from day one: the business owns every account, and outside helpers get access.

Örnek Oto Servis: the filled-in plan

Before you install anything, follow one click from start to finish. Each tool in this guide does one job on this path. Once you know where a tool sits, you know what it can see and what it cannot.

The tools, one line each

Labels that travel with the click

When someone clicks an ad, the platform can add an ID to the link. Google Ads adds gclid when auto-tagging is on, and auto-tagging is now on by default for new accounts Google Ads Help, Oct 2026. Meta adds fbclid, but Google Analytics does not use it to decide where a visit came from. For Meta ads, posts, emails, QR codes and your Google Maps listing, you add your own labels, called UTM parameters (Section 03).

Where data gets lost on the way

• Visits are fewer than clicks. People leave before the page loads, reject cookies (small files a website stores in the browser to recognise a visitor), use ad blockers, or the tag is missing on the landing page.
• WhatsApp hides the source. Links opened from WhatsApp usually arrive with no referrer (the note that tells a site which page sent the visitor), so without UTMs they look like "Direct" visits.
• Apple removes some labels. Link Tracking Protection removes tracking parameters from links shared in Messages and Mail and in Safari Private Browsing (announced for iOS 17) Apple, Jun 2023.
• Safari shortens cookie life. Safari blocks all third-party cookies, and caps cookies set by scripts to 24 hours when the visitor arrives from a known tracking site through a link with click IDs WebKit, Oct 2026.
• Phones and doors have no tags. A real call, a chat or a walk-in only reaches a report if someone writes it down.

When a visit arrives without labels, Google Analytics guesses where it came from. The guesses are often wrong: paid Meta clicks can show up as "Organic Social" or "Referral", and links opened from WhatsApp or a QR code look like "Direct". UTM labels remove the guessing. They cost nothing and take a minute per link.

The parameters

Naming rules

Google states that "parameter values are case sensitive" Google Analytics Help, Oct 2026. So Instagram, instagram and IG become three separate rows in your reports. Fix the spelling once and never improvise:

• Lowercase only. No spaces.
• No Turkish letters (ç ğ ı İ ö ş ü). They turn into codes like %C4%B1 and split reports. Write kis_bakimi, not kış_bakımı.
• Use underscores between words, no spaces and no hyphens, so every value follows one pattern (kis_bakimi_2026_11). This course uses underscores everywhere.
• Put the year and month in campaign names, so next year's winter campaign gets its own row.
• Use only values from your naming list, and keep every tagged link in one "UTM log" sheet (date, link, source, medium, campaign, content, where it was used).

Örnek Oto Servis naming list

How utm_medium decides the channel

GA4 sorts every visit into a default channel group using fixed rules. The medium you choose decides most of it Google Analytics Help, Oct 2026:

When not to add UTMs

Google Ads: leave the links clean. Auto-tagging adds gclid, and when both are present GA4 "uses the auto-tagged values for source, medium, and other traffic-classification dimensions" Google Analytics Help, Oct 2026. Half-finished manual UTMs on Google Ads only create (not set) rows. Check that auto-tagging is on in Google Ads › Admin › Account settings › Auto-tagging (path not re-verified). Add manual UTMs only if another tool, such as a call-tracking service, needs them, and then add the full set.

Links inside your own website (a banner on your home page pointing to the winter offer): do not tag them. A UTM on an internal link overwrites the real source of the visit. This is widely given advice; it was not re-checked on a Google page.

Where Örnek uses UTMs

1. Meta ads

   Add UTMs to every Meta ad, or paid clicks often show up as Organic Social or Referral. In Ads Manager, at the ad level, use Tracking › URL parameters (path not re-verified). The safe way is a fixed string per ad:

   utm_source=instagram&utm_medium=paid_social&utm_campaign=kis_bakimi_2026_11&utm_content=video_usta_a

   Copy

   Dynamic parameters. Meta can also fill in values by itself when someone clicks. You type a placeholder in double curly brackets, and Meta swaps it for the real value. Eight placeholders are listed: {{campaign.name}}, {{campaign.id}}, {{adset.name}}, {{adset.id}}, {{ad.name}}, {{ad.id}}, {{site_source_name}} and {{placement}}. They go in the ad's Destination › URL parameters field below the website address, not inside the address itself Terminus, Sep 2026. {{site_source_name}} fills in a short network code: fb, ig, an (Audience Network) or msg (Messenger) Craftshift, Jul 2026. Both are secondary sources; Meta's own help page did not load for this check (Oct 2026). A dynamic string for Örnek:

   utm_source=instagram&utm_medium=paid_social&utm_campaign={{campaign.name}}&utm_content={{ad.name}}&utm_id={{campaign.id}}

   Copy

   Meta copies names exactly as typed, so name Meta campaigns and ads with the same rules as UTMs: lowercase, underscores, no Turkish letters (kis_bakimi_2026_11, video_usta_a). The ID keeps working even if you rename a campaign later. After launch, open GA4 Reports › Acquisition › Traffic acquisition and check that the visits show as Paid Social. Whether GA4 recognises fb and ig as social sources was not verified, so this guide keeps a fixed utm_source (instagram or facebook) per ad instead of {{site_source_name}}.

2. Google Business Profile website link

   The visit stays in Organic Search, and you can filter campaign = gbp_listing to separate Maps visits from normal Google search visits.

   https://ornekotoservis.com.tr/?utm_source=google&utm_medium=organic&utm_campaign=gbp_listing

   Copy
3. Instagram bio link and WhatsApp status

   Organic posts use utm_medium=social: ?utm_source=instagram&utm_medium=social&utm_campaign=bio_link and ?utm_source=whatsapp&utm_medium=social&utm_campaign=kis_bakimi_2026_11.

4. QR codes on flyers, invoices and car stickers

   Print a short address you control, for example ornekotoservis.com.tr/kis, and let it redirect to the tagged link. The printed code then never has to change. The visits appear as Unassigned (no rule matches print); filter by campaign, or create a custom channel group "Offline/Print" in Admin › Data display › Channel groups (path not re-verified).

   https://ornekotoservis.com.tr/kis-bakimi?utm_source=flyer&utm_medium=print&utm_campaign=kis_bakimi_2026_11&utm_content=flyer_a5_a

   Copy
5. Newsletter and SMS

   utm_medium=email for emails; utm_source=sms or utm_medium=sms for text messages.

Build a link

Fill in the fields. The builder makes everything lowercase, changes spaces and hyphens to underscores, replaces Turkish letters and warns you about common mistakes. Google's own Campaign URL Builder does the same job without the warnings.

https://ornekotoservis.com.tr/kis-bakimi?utm_source=instagram&utm_medium=paid_social&utm_campaign=kis_bakimi_2026_11&utm_content=video_usta_a

Google Analytics 4 (GA4) is Google's free website statistics tool. It counts visits, reads where each visit came from (Section 03), and records what people did on the site. It cannot see calls, chats or invoices, but it is the one tool here that shows website visits from every source side by side.

Set up a new property

1. Create the account and property

   At analytics.google.com go to Admin › Create › Account (business name), then Property. Set the reporting time zone to Türkiye and the currency to Turkish lira (TRY). Fill in the business details and choose the lead-generation business objective.

2. Create a web data stream

   Enter the site address, keep Enhanced measurement switched on, and copy the Measurement ID (G-XXXXXXX).

3. Install the tag, with one method only

   Through Google Tag Manager (recommended, Section 05), directly in the <head> of every page, or through a plugin such as Site Kit by Google for WordPress. Two methods at once count every visit twice.

4. Set data retention to 14 months on day one

   Admin › Data collection and modification › Data retention › Event data retention = 14 months › Save. The default is 2 months, and the change does not work backwards Google Analytics Help, Oct 2026.

5. Filter your own staff (optional)

   Define the shop's IP address as internal traffic and filter it, so the team's daily visits for prices and the address do not count. The setting is under the data stream's Configure tag settings (path not re-verified).

6. Link Google Ads and Search Console

   Admin › Product links › Google Ads links and Admin › Product links › Search Console links. Details below.

7. Check that data arrives

   Open Reports › Realtime and visit the site from your phone. For single events, use DebugView (GA4's live list of events from a test device) together with GTM Preview, the test mode of Tag Manager (Section 05).

8. Mark key events

   After your events have fired at least once: Admin › Data display › Events, then click the star next to click_to_call, whatsapp_click and generate_lead.

What enhanced measurement gives you, and what it does not

With enhanced measurement on, GA4 records these events without extra setup Google Analytics Help, Oct 2026:

Events, key events and conversions

• How to mark: Admin › Data display › Events → star icon, or + Create event with "Mark as key event" switched on. Changes can take up to 24 hours to show in standard reports. Unmarking does not delete past data Google Analytics Help, Oct 2026.
• Limit: 30 key events per standard property (50 in the paid Analytics 360) Google Analytics Help, Oct 2026. You need three or four.
• Counting: "once per session" usually fits leads; "once per event" fits purchases Analytics Mania, Oct 2026. With "once per event", a customer who refreshes the thank-you page counts as two leads.
• Never mark page_view as a key event. It would count every page view as a lead.

Recommended lead events

Google recommends a set of event names for lead generation. If you use them, GA4 fills a Lead acquisition report Google Analytics Help, Oct 2026.

The reports a beginner needs

"How many people came from my ad?"

1. Read ad clicks in the ad platform

   Google Ads shows "Clicks"; Meta shows "Link clicks". GA4 does not count ad clicks.

2. Read visits in GA4

   Open Traffic acquisition, switch the first column to Session source / medium or Session campaign, find google / cpc or instagram / paid_social, and read Sessions.

3. Expect fewer sessions than clicks

   People leave before the page loads, reject cookies or block ads, or the tag is missing on the landing page. A small gap is normal. A very large gap means a broken tag or a slow page.

"How many of them tapped call or WhatsApp?"

1. Stay in Traffic acquisition

   In the key events column, pick one key event, for example click_to_call, then whatsapp_click.

2. Read the count per campaign or source

   This is the number of taps, not of finished calls or chats.

3. Compare with the phone system

   For real calls, compare with the call log of the tracking number used for that channel (Section 08).

Two settings that confuse beginners

Link Google Ads and Search Console

• Google Ads: Admin › Product links › Google Ads links. You need the Editor or Administrator role in GA4 and admin access in Google Ads. Ads data appears in GA4 within 48 hours Google Analytics Help, Oct 2026.
• Search Console: Admin › Product links › Search Console links. This adds the "Google Organic Search Queries" and "Google Organic Search Traffic" reports. The report collection is unpublished by default; publish it from Library. One web stream links to one Search Console property Google Analytics Help, Oct 2026.

Without Tag Manager, every new piece of tracking means asking your web developer to edit the site. With it, the developer installs one container once, and you add or change tracking yourself. For a shop that needs the same three actions (call, WhatsApp, form) sent to three tools, GTM is the practical hub.

Set up the container

1. Create the container

   At tagmanager.google.com create an account and a container with target platform Web. Install its two code snippets on every page (one in the <head>, one right after <body>), or use your website platform's GTM integration.

2. Add the Google tag

   Tags › New › Google tag. Tag ID = your G-XXXXXXX. Trigger = Initialization – All Pages.

3. Switch on built-in variables

   Variables › Configure: tick Click URL, Click Text, Click Element, Page Path, Page URL and Form ID.

4. Add a Conversion Linker tag

   Tag type Conversion Linker on All Pages. It stores Google's click ID so that later conversions can be matched to the ad click.

Track taps on the phone number

1. Trigger

   Triggers › New › Click – Just Links › Some Link Clicks, condition Click URL starts with tel:. Name it TRG – tel click.

2. GA4 event tag

   Tags › New › Google Analytics: GA4 Event. Event name click_to_call. Parameters: link_url = {{Click URL}}, page_path = {{Page Path}}. Trigger TRG – tel click.

3. Google Ads tag (optional, for bidding)

   In Google Ads create a website conversion action of type click, for example "Lead – Phone click (web)". In GTM add a Google Ads Conversion Tracking tag with its Conversion ID and Conversion Label, on the same trigger Google Ads Help, Oct 2026.

4. Meta tag (optional)

   A Meta Pixel Contact event on the same trigger (see below).

Track taps on WhatsApp links

WhatsApp buttons can link to several addresses. One GTM trigger cannot hold "OR" conditions, so use one regular expression (a pattern that matches several texts) Boei, Oct 2026:

Trigger type:  Click – Just Links › Some Link Clicks
Condition:     Click URL  matches RegEx
Pattern:       wa\.me|api\.whatsapp\.com|web\.whatsapp\.com|^whatsapp:
Name:          TRG – whatsapp click
GA4 event:     whatsapp_click   (same parameters as click_to_call)

If the WhatsApp button is a floating widget that is not a normal link (an iframe or a script button), use Click – All Elements with a CSS selector, or the widget's own dataLayer event (a message the page code sends to GTM). Test it in Preview.

Track forms that were really sent

Do not rely on enhanced measurement's form_submit as your only lead count. It fires on the attempt and does not know whether the message arrived.

Track the "Yol tarifi al" link

Many repair customers want to know where the shop is before they drive over. If your website has a Yol tarifi al (get directions) button that opens Google Maps, track it the same way as the phone link. Google Maps links come in a few forms, so one regular expression covers them all:

Trigger type:  Click – Just Links › Some Link Clicks
Condition:     Click URL  matches RegEx
Pattern:       google\.[a-z.]+/maps|maps\.google\.|maps\.app\.goo\.gl|goo\.gl/maps
Name:          TRG – directions click
GA4 event:     directions_click   (same parameters as click_to_call)
Meta event:    FindLocation (optional)

Two rules keep this count honest. First, write every pattern into one condition: if you add two "Click URL contains" lines to the same trigger, GTM fires only when both are true, so it never fires. Second, a directions tap shows interest; it does not prove the person came. Count directions_click as a secondary signal in GA4 (a key event only if you want it in reports), and do not make it a Primary conversion in Google Ads. Most direction requests happen on Google Maps itself, not on your site; you read those in the Business Profile Performance report (Section 10).

Send the same actions to Meta

• Add the Meta Pixel base code on all pages, from the GTM Community Template Gallery or as Custom HTML, and only after the visitor's cookie consent (Section 13).
• Event tags: fbq('track','Contact') on the phone and WhatsApp triggers, fbq('track','Lead') on the thank-you page, fbq('track','Schedule') for finished bookings.
• If you also send events from your server (Conversions API, Section 07), pass the same event ID from both sides so Meta counts each action once Meta for Developers, Oct 2026.

Test, then publish

1. Preview

   In the workspace click Preview, enter the site address, click Connect, then Continue in the Tag Assistant tab Tag Manager Help, Oct 2026.

2. Do each action once

   Tap the phone link, tap the WhatsApp button and send a test form. In Tag Assistant every tag should show "Fired" exactly once.

3. Check the receiving tools

   GA4 DebugView or Realtime, the Google Ads conversion status, and Meta Events Manager › Test events.

4. Publish with a name

   Submit, write a version name such as "v3 – tel + whatsapp + form", then Publish. Since 17 September 2026 GTM can suggest an AI-written version summary Tag Manager release notes, Sep 2026.

5. Check again after 24–48 hours

   Mark the new GA4 events as key events, and compare the counts with the calls and form emails you really received.

Google Ads uses the conversions you give it to decide whom to show ads to and how much to bid. If you count the wrong thing, it optimises for the wrong thing. This section covers only the measurement side; campaigns and bidding are in the Google Ads deep dive.

Three ways to count

Örnek's conversion actions

Give each action a value so bidding knows which matters more. Work it out from your own numbers: value of a lead ≈ lead-to-job rate × gross profit per job. With Örnek's example numbers, if 4 in 10 form leads become jobs worth 3,200 TL gross profit, a form lead is worth about 0.4 × 3,200 = 1,280 TL. Use a lower value for an action that converts worse.

Enhanced conversions and offline uploads

• Enhanced conversions send a hashed (SHA-256, a one-way scrambling) email or phone number from your form, so Google can match more conversions to ad clicks. "As of April 2026, enhanced conversions for web and leads are now combined into a single on/off setting." You must accept Google's customer data terms Google Ads Help, Oct 2026.
• Offline conversion import (GCLID method): save the gclid from the landing address in a hidden form field so it arrives with the lead. Create an Import conversion action such as "Job completed (offline)". Every week, upload Google Click ID, conversion name, conversion time with time zone (2026-10-01 14:30:00+03:00), value and currency (TRY) through Data Manager.
• Google's recommendation: "If you have not already adopted offline conversion import, we recommend starting with enhanced conversions for leads instead." Google reports a "median 10% increase in conversions" (vendor claim) Google Ads Help, Oct 2026. Run old and new actions side by side for "1–2 conversion cycles or 4 weeks" before making the new one Primary Google Ads Help, Oct 2026.

Calls from Google Ads in Türkiye

Google says that tracking call conversions from ads and from a website, and importing call conversions, "require Google forwarding numbers" Google Ads Help, Oct 2026. Google forwarding numbers are available in 30 listed countries, and Türkiye is not on the list Google Ads Help, Oct 2026. In practice:

Google's page also lists a "call ad clicks" option that counts clicks on call assets without forwarding numbers. This was not tested in a Turkish account (Oct 2026). If you use it, treat it as clicks, not calls.

Meta decides who sees your ads partly from the events it receives. If it only sees clicks, it finds people who click. If it sees leads and booked jobs, it can look for people who book. The Pixel and the Conversions API are the two roads those events travel on.

Meta says advertisers who use the Conversions API together with the Pixel saw on average "17.8% lower cost per result". In April 2026 it announced a free one-click "Meta-enabled" Conversions API setup Meta, Apr 2026. Both are Meta's own claims about its own product.

Standard events for a repair shop

Set it up

1. Create the dataset and install the Pixel

   Events Manager › Connect data sources › Web, then create or choose a dataset (Pixel). Install it through a website-platform integration (WordPress, Wix, Shopify), through GTM (Section 05), or as code.

2. Pick the simplest Conversions API route that works

   A partner integration in your website platform; the one-click Meta-enabled setup if your account offers it; the Conversions API Gateway, which runs in your own AWS or Google Cloud account where "the only cost … is the associated cloud resource or partner fees" Meta for Developers, Oct 2026; server-side GTM (more technical); or direct code by a developer.

3. Deduplicate

   Send the same event_name and event_id from browser and server Meta for Developers, Oct 2026.

4. Test

   Events Manager › your dataset › Test events. Open your site, trigger Contact and Lead, and check that both "Browser" and "Server" appear and are deduplicated.

5. Verify your domain

   Business settings › Brand safety › Domains, with an HTML file, a DNS TXT record or a meta tag. It proves you own the domain and controls who can edit link previews in ads pointing to it Meta for Developers, Oct 2026.

6. Check Event Match Quality

   Events Manager shows an Event Match Quality score per event: how well Meta can match your events to people. More customer details (hashed email or phone), sent only with consent, improve it. The scoring details were not re-verified for this guide.

Measuring Click-to-WhatsApp ads

Sending paid jobs to Meta

Meta's separate Offline Conversions API was discontinued on 14 May 2025 Jon Loomer, Oct 2026 CustomerLabs, Oct 2026 (secondary sources). Offline events now go through the normal Conversions API to the same dataset, for example a Purchase with value and an action_source that says where it happened:

Most repair customers phone, write on WhatsApp or simply drive in. These are exactly the contacts that website tags miss. In Türkiye the gap is wider, because Google Ads cannot count real calls here (Section 06). You close the gap with your own phone numbers and one good question.

What the tools cannot see here

• Real calls from Google Ads. No Google forwarding numbers in Türkiye, so no "calls from ads", no website call tracking through forwarding numbers and no imported calls Google Ads Help, Oct 2026.
• Calls dialled by hand. Many people read the number from the site, from Google Maps or from a sticker and type it. No tap, no event.
• Taps that never connect. A tel: tap opens the dialler; the person may hang up, or nobody answers.
• Missed calls (cevapsız çağrılar). Only the phone system's log shows them. Unanswered calls in busy hours can be the largest hidden loss of all.
• Word of mouth and passers-by. No tool sees a neighbour's tip or the sign over the door.

Three main methods

Smaller methods that add detail

Example providers (not tested)

• Turkish cloud-PBX and number providers sell extra geographic numbers (coğrafi numara) or 0850 numbers with a call log: Netgsm (0850, geographic and 0800 numbers, Bulut Santral, "Çağrı Analizi", API), Bulutfon (0850 and geographic numbers, call dashboard, REST API) and Verimor (Bulut Santral, 0850, Sanal Santral). None of their homepages advertised dynamic number insertion or a Google Ads or GA4 integration when checked in October 2026. Prices were not checked.
• Zadarma lists Turkey among its call-tracking countries; call tracking itself is free and you pay for the virtual numbers; it integrates with Google Analytics and shows UTM tags Zadarma, Oct 2026. Document requirements and number types for Türkiye were not verified.
• International DNI vendors such as CallRail, CallTrackingMetrics and Ringostat: support for Turkish numbers was not confirmed.

Cost per lead is easy to read and often misleading. One channel can bring cheap leads that rarely turn into jobs. Another can bring fewer, more expensive leads that nearly all become paying customers. Only the cost per paying customer tells you where money should go, and only your customer log can give you that number.

The customer log

A Google Sheet is enough: one row per lead, filled in by the front desk at first contact and updated when the car comes in and when the invoice is paid. Turkish column names keep it natural for the team (Müşteri / Talep Takip Tablosu, customer and request tracking sheet).

Match each lead to its job and its money

1. Give every contact a row

   Calls, chats, forms and walk-ins, with the source answer, on the day they happen.

2. Update the status as the car moves

   Quote given, appointment, car arrived, job done or lost. Find the row by Talep No or phone number.

3. Add the invoice and gross profit

   When the job is paid, copy the amount excluding VAT and the gross profit from your accounting.

4. Summarise monthly by source

   A pivot table: leads, jobs, revenue, gross profit per "Bizi nereden duydunuz?" answer and per line. Put ad spend next to it.

The formulas

ROAS uses revenue; ROI uses profit. A high ROAS can still lose money if the margin is thin. All numbers are examples.

Every metric in one table

Reports use many short names. This table lists them in funnel order, from the first view of an ad to the value of a customer over years. The example month is the same as above (30,000 TL spend, 60 leads, 24 paid jobs), with the ad-side numbers from the Crash Course: 100,000 impressions seen by 40,000 people, 2,000 clicks, 1,800 GA4 sessions. All are example numbers for the fictional Örnek Oto Servis.

Worked example: one month, two channels

• Gross profit: 192,000 × 40% = 76,800 TL. ROAS = 6.4. ROI = (76,800 − 30,000) ÷ 30,000 = 156%.
• Break-even is 3,200 TL per customer. Both channels are well below it, so both pay back on the first job. Google is under the 1,500 TL target; Meta is exactly at it.
• The lesson: Meta had the cheaper lead (462 TL vs. 529 TL) but the more expensive customer (1,500 TL vs. 1,125 TL), because fewer of its leads became jobs. Judged on cost per lead alone, you would move money the wrong way.
• Repeat visits raise the value. If a customer returns about twice a year for three years, lifetime revenue is about 48,000 TL and lifetime gross profit about 19,200 TL (example). Count on this only if the log actually shows customers coming back (column 19).

Three free reports show what happens before people reach your website: what they searched, how often they saw your Maps listing, and how your posts did. None needs a tag. Each counts something slightly different from what its name suggests.

How to use them together

• Search Console tells you which searches find you without ads. If "fren balatası değişimi" (brake pad replacement) brings many impressions but few clicks, the page title or description needs work. It also helps pick Google Ads keywords. Linked to GA4 (Section 04), it adds two organic search reports there.
• GBP Performance is the main free report for Maps. Compare its monthly "Calls" with the calls on line B (the number shown only on the profile). The gap shows how many taps did not turn into a call, or how many people dialled by hand.
• The tagged GBP website link (utm_campaign=gbp_listing, Section 03) lets GA4 show what Maps visitors did on the site.
• Meta insights show which organic posts reach people near the shop and lead to profile visits and messages. Use them to choose which posts to turn into ads.

One free extra: Microsoft Clarity

GA4 tells you how many people left a page without calling. It does not show why. Microsoft Clarity fills that gap. It shows heatmaps (a picture of the page coloured by where people tap and how far they scroll) and session recordings (a replay of one visit: where the visitor tapped, scrolled, hesitated and left). Microsoft describes it as "always free" with no traffic limits Microsoft Clarity, Oct 2026.

1. Create a project

   Sign in at clarity.microsoft.com, add a project for the website, and copy its tracking code or project ID.

2. Install it through GTM, behind consent

   Clarity sets cookies and sends visit data to Microsoft, so treat it like GA4: put it in the analytics category of your cookie banner and fire it only after consent (Section 13). For visits from the EEA, the UK and Switzerland, Clarity has required a consent signal since 31 October 2025 PPC Land, Aug 2025.

3. Watch 10–15 recordings a month

   Filter to mobile visits on your key pages (the booking form, the price page). Note where people stop, tap on things that are not links, or never reach the WhatsApp button.

Bing and Yandex: how much do they matter?

For a Turkish shop, Google's free reports (Search Console, Business Profile) come first. Yandex is large enough that you should check how your shop appears on Yandex Maps and in Yandex search (see the SEO & Local Search deep dive). Bing is small in Türkiye, so the Microsoft Advertising conversion tag (UET) is only needed if you actually run Bing ads. Read these shares as one measurement company's estimate, not an exact count.

Add up the conversions that Google Ads and Meta report, and the total is often higher than the number of customers who actually came. Each tool follows its own counting and credit rules, so the totals differ. Once you know the rules, the gaps stop being alarming.

Five reasons the numbers never match

• Different counting: a GA4 session, a Google Ads click and a Meta link click are different things.
• Self-credit: each ad platform credits its own ads. GA4 spreads credit across channels.
• Different windows: Meta can count a conversion days after a click, or a day after a view without any click.
• Missing data: rejected cookies, ad blockers, iOS and Safari limits.
• Estimates: Google and Meta model some conversions they cannot see.

The models each tool uses (as of 2026)

Meta changed its attribution twice in 2026

• 12 January 2026: Meta removed the 7-day view and 28-day view windows (announced 13 October 2025). The 1-day click, 7-day click, 28-day click, 1-day engaged-view and 1-day view windows remained. Sources conflict on where this applied: PPC Land says the Ads Insights API only PPC Land, Oct 2026; Dataslayer says Ads Manager too Dataslayer, Oct 2026. Check the attribution settings in your own account.
• March 2026: click-through attribution for website and in-store conversions was narrowed to "exclusively include link clicks". Likes, shares and saves moved to engage-through attribution (formerly engaged-view), and the video threshold went from 10 to 5 seconds Meta, Mar 2026 Dataslayer, Apr 2026.

Same lead, different day: click date vs conversion date

Even when two tools agree that a lead came from an ad, they can put it on different days. Google Ads "has always reported conversions by the date your ad was clicked" Google Ads Help, Oct 2026. GA4 reports a key event on the day it happened Dataslayer, Jun 2024 (secondary).

Data also arrives late. Recent days in every tool are incomplete, and Google Ads can still add conversions to a click that happened weeks ago, up to the end of the window. Judge last week on Monday, but treat the last two or three days as provisional.

A practical approach for a small shop

1. Make your log the source of truth

   Real customers, jobs and money come from the log (Section 09). Platform numbers are for steering inside each platform.

2. Judge the total with blended numbers

   These do not depend on any platform's attribution rules (formulas below).

3. Compare trends, not totals

   Keep the same settings and date ranges week to week. When a platform changes a definition, write a note in your report so the jump is explained.

4. Run a simple on/off test when in doubt

   Pause one channel for 2–4 weeks, or run it only in some districts, and compare new customers in the log with similar weeks. Small shops have small numbers, so treat the result as a strong hint, not proof. This is a judgement rule, not a sourced benchmark.

Data is only useful if someone looks at it on a fixed day and makes one decision. A 15-minute report every Monday is enough for a shop: spend, leads by channel, jobs, revenue, cost per lead, cost per job, and one change for next week.

Connectors: what plugs in for free

Build the dashboard

1. Start a blank report

   At datastudio.google.com choose Blank report.

2. Add data

   GA4, Google Ads, Search Console, and Google Sheets (the customer log, plus the sheet with weekly Meta and GBP numbers).

3. Page 1, Summary

   Scorecards for spend, leads, jobs, revenue and cost per job; a weekly time series; a table by channel.

4. Page 2, Website and search

   GA4 sessions and key events by channel, top landing pages, Search Console queries, GBP monthly numbers.

5. Add a date control and share

   Default "Last 7 days" or "Last month"; share as view-only.

The weekly report template

Five questions every Monday

1. Did new paying customers go up or down against the last 4-week average?
2. Which paid channel had the lowest cost per job (not cost per lead)?
3. Did any tracking break? Look for an event at zero or a sudden jump.
4. How many calls were missed, and at what times?
5. What one change do we make this week? Write it in the change log.

With only a few leads a week, make budget decisions monthly; weekly numbers are noisy.

The monthly review (about one hour)

On the first Monday of the month, give the numbers one longer look. The weekly check asks "is anything broken?"; the monthly review asks "where should next month's money go?"

• New paying customers by source from the log → cost per customer per channel and blended cost per customer (Sections 09, 11)
• Revenue and gross profit from ad customers → ROAS and ROI, compared with break-even (Section 09)
• Business Profile Performance: calls, directions, website clicks, top search terms (Section 10)
• Search Console: top queries and pages; share of returning customers in the log; review count and rating
• Microsoft Clarity: watch 10–15 mobile recordings of the booking page and note where people get stuck (Section 10)
• Compare with the same month last year, not only with last month (see seasons below)
• Decide for each campaign: keep and scale, fix one thing, or stop. Write the decision in the change log

These ticks are saved in this browser. Untick them to reuse the list next month.

Small numbers, seasons and simple tests

A shop with 60 leads a month sees about 15 a week. At that size, luck moves the numbers a lot. Three habits stop you from reacting to noise. These are rules of thumb, not statistical standards.

Diagnose from the top of the funnel down

Every tool in this guide sets cookies or sends personal data to companies abroad. KVKK, Türkiye's personal data protection law (Law No. 6698), sets the rules. A banner that is shown while the tags fire anyway is a legal risk and also gives you wrong data.

KVKK's cookie guide (July 2025)

The guide is Çerez Uygulamaları Hakkında Rehber (Guide on Cookie Practices), current edition KVKK Yayınları No: 69, Temmuz 2025 (July 2025). KVKK published a draft in January 2022 and the first final guide in June 2022 KVKK, Jul 2025. Its main points:

• No consent needed only for cookies used purely to carry a communication over the network, or cookies strictly necessary for a service the user asked for.
• First-party analytics may fall under the strictly-necessary exemption only if it measures audience and runs the site, produces anonymous statistics without cross-site tracking, has a reasonable lifetime, and the data is not passed to third parties. GA4 and the Meta Pixel send data to Google and Meta abroad; this guide's reading, shared by a Turkish legal blog, is that they need consent DijiLegal, Jul 2026.
• Advertising cookies: "Davranışsal reklamcılık için kullanılan çerezler açık rıza gerektirmektedir." (Cookies used for behavioural advertising require explicit consent.)
• Banner design: "Kabul et", "Reddet" and "Tercihler" buttons equal in colour, size and font; consent-based cookies off by default; a small icon to change the choice later; cookie walls can make consent invalid; do not ask on every visit (consent fatigue).
• Shared responsibility: the site owner and the third party (for example the ad platform) are both responsible for informing users and getting consent.
• Scope: the guide gives no guidance on pixels, fingerprinting, local storage or beacons. Most ad and analytics tags also set cookies, so the cookie rules still apply to them.

Real fines

Data sent abroad (Article 9)

Law No. 7499 amended KVKK Article 9 on transfers abroad. Transfers can rest on an adequacy decision, on appropriate safeguards such as standard contracts (which must be notified to KVKK within five business days of signing), or on limited incidental transfers. It took effect on 1 June 2024; the old explicit-consent rule ran in parallel until 1 September 2024. The implementing regulation was published in the Official Gazette on 10 July 2024 (No. 32598) Resmî Gazete, Mar 2024 KVKK, Oct 2026. Base fines under Article 18 include 50,000–1,000,000 TL for not notifying a standard contract; amounts are revalued every year and the 2026 figures were not checked. How a small business should document the Article 9 basis for GA4 and Meta is not settled in the sources read. Ask a lawyer.

Google Consent Mode v2

Consent mode passes the visitor's choice to Google tags. Consent types are ad_storage, ad_user_data, ad_personalization and analytics_storage (plus functionality, personalization and security storage) Google for Developers, Oct 2026. Google requires consent signals for traffic from the EEA, the UK and Switzerland, not for Türkiye. It is still a clean way to make Google tags obey your banner. It has two modes. In basic mode, Google tags do not load until the visitor consents. In advanced mode, they load with consent set to "denied" and send cookieless pings (small signals without cookies), which Google uses to model lost conversions.

Set up the banner

1. Choose a consent management platform (CMP)

   One with Turkish texts, a KVKK mode, category-based consent and Google consent mode support. Examples: CookieHub, Çerezgo, Cookiebot, Usercentrics, CookieYes, Complianz (WordPress). Features and prices were not verified.

2. Set the categories

   Zorunlu (strictly necessary, no consent), İşlevsel (functional), Analitik/Performans (analytics), Reklam/Pazarlama (advertising). Analytics and advertising off by default.

3. Design the first layer

   "Kabul et", "Reddet" and "Tercihler" equal in colour, size and font, a link to the Çerez Aydınlatma Metni (cookie notice), and a small icon to change the choice later.

4. Connect it in GTM

   Install the CMP template on Consent Initialization – All Pages with defaults set to denied. Google tags use their built-in consent checks; give the Meta tags "Additional consent checks" or consent-based triggers.

5. Test with "Reddet"

   Open the site in a private window and reject. In Tag Assistant the Meta Pixel must not fire and Google tags must not set cookies. Then accept: the tags fire.

Browser and phone limits

Before uploading customer data

Phone numbers, emails and click IDs of customers are personal data. Hashing them (SHA-256) is pseudonymisation; the data stays linked to a person. Before uploading paid jobs to Google or Meta: have a legal basis (for advertising and measurement, typically explicit consent), say in your aydınlatma metni that contact data may be shared with ad platforms, address the transfer abroad, and accept the platform's customer-data terms. The lower-risk start is to keep the log in-house and use it only for totals per channel.

Promotional SMS and e-mail: the İYS rules

Customer phone numbers in your log are tempting for campaign messages ("Kış bakımında %10 indirim"). Türkiye regulates these separately from KVKK, under Law No. 6563 on electronic commerce and its regulation on commercial electronic messages. İYS (İleti Yönetim Sistemi, the national message management system) is where consents are recorded.

When you do send a campaign message, tag its link with UTMs (utm_source=sms&utm_medium=sms or utm_medium=email, Section 03), and record the İYS consent date in column 10 of the customer log (Section 09).

Setup checklist for Örnek Oto Servis

Your ticks are saved in this browser. Work top to bottom; each step relies on the ones before it.

Week 1 · Plan and foundations

• Write the measurement plan: goal, KPIs, every contact action, owners (Section 01)
• Check that the shop owns every account (Google Ads Admin, GA4 and GTM Administrator, GBP owner, Meta business portfolio); give helpers lower access (Section 01)
• Create the UTM naming list and the "UTM log" tab (Section 03)
• Create the customer log sheet with the 20 columns and the "Bizi nereden duydunuz?" drop-down (Section 09)
• Brief the front desk: ask the question at every first contact, fill in the log daily (Section 08)
• Install a cookie banner (CMP) with analytics and advertising off by default; publish the cookie notice (Section 13)

Week 2 · Tags and tools

• Create the GA4 property: time zone Türkiye, currency TRY, data retention 14 months, staff IP filtered (Section 04)
• Install GTM on every page; add the Google tag and Conversion Linker; remove any second GA4 install (Section 05)
• Add triggers and GA4 events for tel: taps, WhatsApp taps and the /tesekkurler page (Section 05)
• If the site has a "Yol tarifi al" button, add the directions trigger and directions_click (Section 05)
• Connect the banner to GTM consent settings and test with "Reddet" (Section 13)
• Create Google Ads conversion actions; one Primary per action, no double counting (Section 06)
• Install the Meta Pixel (after consent) with Contact and Lead; add the Conversions API with matching event IDs; verify the domain (Section 07)
• Test everything in GTM Preview, GA4 DebugView and Meta Test events; publish a named GTM version (Section 05)

Week 3 · Links, calls and reports

• Mark click_to_call, whatsapp_click and generate_lead as key events (Section 04)
• Link GA4 with Google Ads and Search Console; publish the Search Console reports from Library (Section 04)
• Check that auto-tagging is on in Google Ads; add UTMs to every Meta ad (Section 03)
• Add the UTM link to the Google Business Profile website field (Section 03)
• Get tracking numbers: line A for the Google Ads call asset, line B for GBP, line C for print (Section 08)
• Create WhatsApp Business labels: Reklam – Instagram, Randevu verildi, İş tamamlandı (Section 07)
• Install Microsoft Clarity through GTM, in the analytics consent category (Section 10)
• Build the Data Studio dashboard and hold the first 15-minute Monday report (Section 12)

Month 2 and later

• Compare platform leads with the log and the call log; fix any gap (Sections 08–11)
• After a KVKK review, add a hidden gclid field and start weekly offline uploads of paid jobs (Sections 06, 13)
• Hold the one-hour monthly review on the first Monday; compare with the same month last year (Section 12)
• Before any campaign SMS or e-mail: register in İYS and send only to people whose consent is recorded there (Section 13)
• Re-test all tags monthly and after every website change; make one test call and one test WhatsApp per number

Common tracking mistakes

1. GA4 installed twice (a plugin and GTM, or code and GTM): every page view counts twice.
2. The same lead counted twice in Google Ads: native tag and imported GA4 key event both Primary.
3. A form counted twice: on the submit click and on the thank-you page.
4. Leads counted "once per event": refreshes of the thank-you page add leads. Use "once per session".
5. page_view marked as a key event: every page view becomes a "lead".
6. No real thank-you page and relying on form_submit: failed sends are counted.
7. No testing after website changes: theme updates often break click triggers.
8. Mixed UTM spelling: Instagram, instagram, IG and Turkish letters split reports.
9. UTMs on internal links: they overwrite the visit's real source.
10. Manual UTMs on Google Ads: not needed with auto-tagging; incomplete ones create (not set).
11. No UTMs on Meta ads: paid traffic looks like Organic Social or Referral.
12. Data retention left at 2 months: explorations cannot look further back.
13. Too many Primary conversions (scrolls, page views, video plays): Google Ads optimises for cheap, useless actions.
14. Treating taps as calls and ignoring missed calls in the phone log.
15. Banner shown, tags fire anyway: a legal risk and a data problem. Test with "Reddet".
16. Comparing platforms carelessly: Meta results (Meta's windows) against GA4 sessions. Compare trends.
17. Changing several things at once: new ads, new page and new budget in the same week. You cannot tell what worked.
