If your Google Ads conversion tracking is not working, work through these causes in order: the tag is not installed or not firing, you are counting the wrong action, consent mode is blocking measurement, conversions are being double-counted, or a recent site change broke the setup. The checks below are ordered from the most common causes to the less obvious ones. They take about an hour and fix many common cases.

Check 1: Is the tag actually firing?
Open the page where the conversion happens and use Google Tag Assistant (free Chrome extension) to see which tags fire. Common findings:
- Tag missing entirely. It was never added to the new page template, or a site redesign dropped it.
- Tag on the wrong pages. A purchase tag placed on every page instead of only the thank-you page records nonsense.
- Tag firing but erroring. Tag Assistant shows the error — often a wrong conversion ID or label copied from the Ads account.
Verify the conversion ID and label character by character against what Google Ads shows under Tools, then Conversions. Menu labels in Google Ads can change over time, so use the account search if you cannot find Conversions where described here. One mistyped character is enough to break everything silently. If the tag was never set up properly, our Google Ads conversion tracking setup guide walks through GA4 and Tag Manager from scratch.
Check 2: Are you counting the right action?
Many businesses track page views or button clicks as conversions when the real goal is a completed booking or purchase. Ask: does this event mean money changed hands or a genuine lead arrived? If not, it is the wrong event. For background, see what conversion tracking is and why it matters.
- Track the thank-you or confirmation page, not the form page itself. See best landing page practices for Google Ads for what that confirmation page should include.
- Mark only true business goals as primary conversions; keep secondary events (like newsletter signups) out of bidding.
- If you count button clicks, confirm the click actually completes the action — a click on a phone number link is not the same as a call.
Check 3: Is consent mode blocking tracking?
If your site shows a cookie banner, Google’s consent mode may be holding back tags until visitors accept. Symptoms: some conversions record but far fewer than your real sales, especially from regions with strict privacy rules. If GA4 is affected too, see GA4 conversions not tracking.
- Confirm consent mode is implemented, not just the banner — the two must be wired together.
- Check that the banner’s accept button actually grants consent in the tag setup.
- Consider enabling enhanced conversions, which recover some measurement using hashed first-party data the visitor provided.
Google documents the setup in the Google Ads help center — follow it closely, because half-implemented consent mode is worse than none. If Tag Manager is part of your setup, our Google Tag Manager setup guide covers the basics.
Check 4: Are conversions being double-counted?
If your numbers look too good — more conversions than actual orders — the tag is probably firing twice. Typical causes: the tag installed both directly on the page and through Tag Manager, or a thank-you page that reloads on refresh. Set the counting method to One per ad click for purchases and leads, and remove the duplicate installation. Compare against conversions tracked in Google Analytics 4 to spot duplicates.
Check 5: Look at attribution and timing
Sometimes tracking works but the numbers confuse. A conversion may be attributed to a different campaign than you expect, or recorded days after the click because of the lookback window. Before declaring it broken, compare a full week of ad-reported conversions against your actual orders or CRM leads. Small gaps are normal; large gaps point back to checks 1 through 4. Once tracking is trustworthy, the next lever is improving your website conversion rate.
Verify with a real test conversion
After any fix, do not trust the settings page alone — run a live test. Go through your own funnel exactly as a customer would: trigger the ad, complete the form or purchase with clearly marked test details, then check Tag Assistant to confirm the tag fired and check Google Ads the next day for the recorded conversion. Testing catches silent failures that dashboards miss. Repeat this test after every site update that touches checkout, forms, or the thank-you page. Tracking often breaks quietly after routine site changes — a redesign, a new plugin, a moved page — and a two-minute test after each update prevents weeks of blind spending on data you cannot trust.
When to rebuild from scratch
If the setup has been patched by several people over the years, with tags in the page code, Tag Manager, and a plugin all at once, the fastest fix is often a clean rebuild: one Tag Manager container, one conversion tag per real goal, tested with Tag Assistant before launch. An hour of careful rebuilding beats months of distrusted data. If you are still learning the platform, our beginner guide to running Google Ads covers the account basics.
Frequently asked questions
Why did my conversion tracking suddenly stop working?
A common trigger is a website change: a redesign, a new checkout plugin, or a moved thank-you page. Retrace what changed on the site around the date tracking stopped.
How long does it take for conversions to appear in Google Ads?
In many accounts, conversions appear within a few hours, though timing varies and can take up to about a day. If nothing appears after 48 hours with real conversions happening, something is broken — start with Check 1.
Should I use Google Tag Manager or install the tag directly?
Tag Manager is better for most businesses: one container to manage, easier testing, and no code edits for each new tag. Direct installation is fine for a single simple tag that will never change.
Can I fix tracking myself or do I need a developer?
The diagnosis above needs no coding. Fixes sometimes do — especially consent mode wiring and thank-you page changes. If you get stuck, our team can help with tracking audits, or contact us and we will take a look. More troubleshooting guides live on our blog.
