Google Ads conversion tracking not working?

When Google Ads conversions suddenly look wrong, the first instinct is usually to blame the campaign. But many “campaign problems” are really tracking or lead-path problems. A form changes. A thank-you page disappears. GTM stops loading on a landing page. A conversion tag is removed during a website update. A new page goes live without the same tracking setup as the old one. Before you change bids, budgets, or targeting, it is worth asking a simpler question: Does the website still show the visible tracking and lead-action signals you expect?

TrackCanary checks visible browser-side signals. It does not prove final attribution accuracy, ad account setup, analytics account data, legal compliance, or every possible conversion event. Manual verification may still be recommended.

First: separate tracking visibility from account reporting

Google Ads reporting can look wrong for several reasons. Some are inside the ad account. Some are inside the website. Some are caused by consent behavior, attribution windows, conversion settings, or delayed reporting.

A browser-side check cannot see everything inside Google Ads. It does not access your account, conversion action settings, attribution model, or reporting history.

What it can do is review the visible website layer:

That is a useful first layer because website changes are common and often happen without the performance marketer being told.

does a Google Ads or conversion tracking signal appear visible?
does GTM appear to load?
does the form or lead path appear visible?
did a page or template change?
is the expected thank-you or conversion path still present?

Common reasons conversion tracking appears broken

The most common causes are usually ordinary website changes.

A landing page gets rebuilt. A form starts submitting without sending users to the old thank-you page. A developer changes a template and removes GTM. A plugin update changes how scripts load. A redirect is added. A new campaign uses a URL that was never checked. A single-page app changes state without loading the old conversion trigger.

Other common reasons include:

The page may still look normal to the user. That is why this kind of issue can stay hidden until leads or reported conversions drop.

GTM not loading on the campaign page
conversion tag removed or renamed
wrong trigger or event condition
thank-you page URL changed
form submission behavior changed
consent or cookie behavior delaying tags
mobile page version behaving differently
staging and production using different templates
redirect or SPA behavior changing the flow

What visible checks can review

A visible browser-side check is not a replacement for Google Ads diagnostics, but it can quickly show whether the website layer deserves attention.

It can help review:

This is especially useful before launching traffic to a new landing page or after a website edit.

visible Google Ads and conversion tracking signals
GTM visibility
GA4 or other analytics signals where detectable
visible forms and lead actions
WhatsApp or call actions
obvious changes between checks
whether a developer handoff is needed

What still needs manual verification

Some parts must still be checked manually.

TrackCanary does not prove that Google Ads is counting conversions correctly. It does not access your Google Ads account. It does not confirm conversion action settings, enhanced conversions, attribution, deduplication, or reporting delays.

It also does not prove that a form submission reaches the CRM or inbox.

For important campaigns, you should still:

The website scan is the first review layer, not the final proof.

submit the form yourself
check the thank-you page or post-submit state
confirm the lead reaches the expected inbox or CRM
review Google Ads conversion diagnostics
review GTM preview/debug where needed
check GA4 or other analytics reporting where needed

Quick troubleshooting checklist

If Google Ads conversion tracking looks broken, start with the page itself.

This process is simple, but it prevents wasted time changing campaigns when the real issue is on the site.

1. Open the exact landing page used in the campaign.
2. Check whether GTM appears to load.
3. Check whether visible Google Ads or conversion tracking signals appear.
4. Test the form or lead action manually.
5. Confirm the thank-you page, redirect, or post-submit state still exists.
6. Check mobile as well as desktop.
7. Review consent and cookie behavior.
8. Check whether the page was recently redesigned or moved.
9. Confirm the relevant conversion action inside Google Ads where needed.
10. Send a clear developer handoff if the website layer needs review.

Developer handoff checklist

A useful developer message should be specific.

Instead of saying “conversion tracking is broken,” send something like:

“The campaign landing page does not currently show the expected visible Google Ads conversion tracking signal in a browser-side check. Please confirm GTM loads on this page, the intended conversion tag/trigger is still present, and the form or thank-you flow still matches the tracking setup. Manual Google Ads and GTM verification may still be needed.”

This keeps the conversation practical. It does not overclaim, and it gives the developer a clear place to start.

When ongoing monitoring helps

One manual check is useful before launch. Monitoring helps when the site keeps changing.

For agencies, this matters because client sites are rarely controlled by one person. Developers, clients, designers, plugin updates, consent tools, and landing page builders can all affect tracking.

Monitoring is useful when:

You do not need a huge analytics governance platform to start. For many small agencies, a simple visible tracking watchlist is enough to catch the obvious issues earlier.

campaigns are always running
several client sites need review
clients change pages without warning
new landing pages are launched often
leads depend on forms, WhatsApp, calls, bookings, or quote requests
you want to know when visible signals appear to change or disappear

Next step

Use the free Google Ads Conversion Tracking Checker on the exact page receiving campaign traffic. If the result shows limited or missing visible signals, review the developer handoff and manually verify the important conversion path.

If you manage several client sites, request the assisted agency pilot and add up to 5 sites for first checks.
