How to check your Google Ads conversion tracking
Can you trust the conversions column in Google Ads? A one-hour test for non-specialists, the usual causes of missing or doubled conversions, and what to fix first.
You pay for Google Ads every month, and the conversions column is the number you judge it by. But can you trust that number? This guide shows how to check if Google Ads conversion tracking is working, with a test you can run in under an hour and no Tag Manager knowledge.
Start with the conversions summary
In Google Ads, open Goals, then Conversions, then Summary. You will see every conversion action in the account, each with a status. That status is the quickest health check you have.
A green status means Google is receiving a signal from your site. A status that asks for attention, or reports no recent conversions, usually means the tag worked once and then stopped. That often follows a site update, a new theme or a plugin change.
An action that has never recorded anything usually points to a tag that was never installed. Or it sits on a page your customers never reach.
Primary and secondary actions
Each conversion action is either primary or secondary. Primary actions appear in the main conversions column and guide your bidding. Secondary actions are recorded, but only for reporting.
This catches many owners out. They see zero in the main column and assume tracking is broken, when the conversions are in fact recorded under a secondary action. The reverse also happens: a minor action, such as a page view, is set as primary and inflates the count.
Check which actions are primary and ask one question of each. Is this something you would happily pay for? A form enquiry or a phone call usually is. A visit to the contact page usually is not.
How to check if Google Ads conversion tracking is working
The steps below need access to your Google Ads account and to the inbox or CRM where your enquiries arrive. Block out an hour.
- Note the status of every action on the conversions summary.
- Confirm that the primary actions are the ones you value.
- Click one of your own ads, submit your contact form, and look for the conversion a few hours later.
- Count the real enquiries from last week and compare them with the conversions Google Ads reported.
- If you use Tag Manager, check the date of the last published version.
Step four matters most. It tells you whether the number in the account has anything to do with reality, without opening a single technical setting.
| What the account shows | What it usually means | Where to look |
|---|---|---|
| Zero conversions, inactive status | The tag does not fire | Thank you page and Tag Manager |
| Fewer than your real enquiries | Measurement is losing some | Cookie banner and form behaviour |
| More than your real enquiries | Double counting | Duplicate tags and imports |
| Conversions only in a secondary column | Account setting | Which actions are primary |
The usual causes, in plain words
The most common cause is a tag missing from the thank you page. Your form used to send people to a separate page where the conversion was counted. After an update, the form shows a message on the same page instead, and nothing is counted any more.
Tag Manager is the next suspect. A change made there does nothing until it is published. A trigger can also be listening for a button that has since been renamed or moved.
Some gaps are not mistakes at all. Visitors who refuse cookies are not measured in the usual way, so you will always see somewhat fewer conversions than you receive. Google can also take time to process a conversion, so today's figure is not final.
Double counting is just as dangerous
A number that is too high feels like good news. It is not. Smart Bidding learns from whatever you report, so an inflated count teaches it to chase people who never became customers.
Duplicates usually come from measuring one action in two places. A tag installed directly on the site plus another through Tag Manager is a classic case. So is a conversion imported from Google Analytics on top of one already tracked in Google Ads.
In one measurement audit by the team, Google Analytics reported 162 conversions for 81 real contacts, two for every real one. The measurement audit case study (in Romanian) shows how it was traced and fixed.
Frequently asked questions
How long does a test conversion take to show?
Google says most conversion data appears within 3 hours, and up to 15 hours for attribution models other than last click. Final figures can keep changing after that, so avoid judging a campaign on today's data alone.
Should I pause my ads until tracking is fixed?
Not necessarily. If you bid on conversions, though, broken tracking means the bidding learns from false data. In that case a bidding strategy that does not rely on conversions is the safer choice while you fix it.
Why do Google Analytics and Google Ads show different numbers?
They count by different rules, for example in how they credit a conversion to an earlier click. A small gap is normal. A large gap, or Google Ads reporting more than your real enquiries, usually points to double counting.
Can I see whether the tag is on the page myself?
Yes. Google Tag Assistant lists the tags firing on a page, and you can launch it from the conversions summary in Google Ads. Open your thank you page with it and look for the Google Ads tag.
Conclusion
Check your conversion tracking before you change budgets or ads. Compare the account with your real enquiries and fix whatever does not match. If you would rather the team ran the check for you, send us a request.
