Google Ads Conversion Tracking Troubleshooting Process

Overview

A repeatable, AI-assisted methodology for diagnosing why conversions are not being tracked correctly in Google Ads. The process works by auditing each layer of the tracking stack in sequence — website, GTM, GA4, Google Ads — and using AI to interpret the state of each layer and prescribe fixes.

Introduced by Mark during a review of the Advanced Health & Safety account. Melissa is scheduled to run an internal training session on this methodology.

"You don't have to know anything. You just have to be able to read. And you have to know the right questions to ask."

The Four-Step Process

Work through each layer in order. Do not skip ahead — a misconfiguration at an earlier layer will cause false negatives in later layers.

Step 1 — Website: Identify Conversion Points

Go to the client's website and identify every conversion point (form submissions, button clicks, phone number clicks, thank-you page loads, etc.).

AI prompt approach: Share the landing page with AI and ask it to enumerate all conversion events that should be tracked.

Step 2 — GTM: Verify Tags Are Configured

Open Google Tag Manager and confirm that a tag exists and is correctly configured for each conversion point identified in Step 1.

AI prompt approach: Ask AI to review the GTM container export or screenshot and confirm whether each conversion event has a corresponding, properly scoped trigger and tag.

Step 3 — GA4: Confirm Data Is Being Captured

Open GA4 and verify that the conversion events are actually firing and appearing in reports or the DebugView.

AI prompt approach: Ask AI whether the expected events are present in GA4. If not, ask what configuration changes are needed to capture them.

Step 4 — Google Ads: Confirm Conversions Are Being Imported

In Google Ads, confirm that the relevant GA4 conversion actions have been imported and are recording conversions.

AI prompt approach: Ask AI to review the Google Ads conversion setup and confirm whether the actions are linked, active, and recording data.

Why This Works

Each layer depends on the one before it. Conversion data cannot appear in Google Ads if it was never captured in GA4; it cannot appear in GA4 if GTM tags are misconfigured; GTM tags cannot fire on the right events if the conversion points were never identified in the first place. Auditing in sequence surfaces the root cause rather than chasing symptoms.

AI dramatically accelerates each step — it can parse a GTM container, read GA4 event tables, and interpret Google Ads conversion settings without the operator needing deep platform expertise. The operator's job is to ask the right questions and act on the answers.

When to Use This Process

A client's Google Ads campaigns show zero or implausibly low conversions
Conversion counts in Google Ads do not match GA4 or CRM data
A new campaign or account is being set up and tracking needs to be verified before spend begins
After any significant website change (new forms, new thank-you pages, redesign)
