Is Your Conversion Tracking Broken? 6 Signs You’re Optimising Blind

Here’s a brutal truth: most ad accounts are optimising based on wrong data. In our audits, we find broken or misconfigured conversion tracking in the majority of accounts we review. If your tracking is wrong, every decision you make — budget, audience, bid strategy — is based on fiction.

Why conversion tracking matters more than any other metric

Without accurate conversion tracking, you don’t know which campaigns generate leads. You don’t know which keywords convert. You can’t use Smart Bidding effectively because Google’s algorithm has nothing to learn from. Meta’s algorithm can’t find more people like your converters because it doesn’t know who they are.

6 warning signs your tracking is broken

1. Your conversion count is suspiciously high

If you’re seeing 500 conversions from 100 clicks, your thank-you page event is firing multiple times per visit, or your conversion is firing on every page. This inflates your data and makes Google optimise for the wrong behaviour.

2. Your conversion count is zero

Obvious, but often missed for weeks. If no conversions are showing in Google Ads or Meta Events Manager, your Pixel or GA4 event isn’t firing at all. Check the thank-you page URL, check for URL discrepancies (www vs non-www, http vs https), and use Meta Pixel Helper or Google Tag Assistant to verify.

3. Google Ads and GA4 show completely different numbers

A 10–20% discrepancy is normal due to attribution differences. A 50%+ discrepancy means one of them is wrong. Usually it’s GA4 undercounting due to cookie consent or ad blockers, or Google Ads overcounting due to duplicate conversion actions.

4. You have multiple conversion actions active in Google Ads

Many accounts have 5, 6, or 7 conversion actions all set to “primary.” Google counts all of them. This means a single user visiting your thank-you page might trigger 4 different conversion events simultaneously, massively inflating your numbers.

5. Your Meta Pixel is firing on every page

If Lead events fire on every page instead of just the thank-you page, Meta thinks everyone is a converter. The algorithm will optimise for page visitors, not actual leads. Use Meta Events Manager → Test Events to check your Pixel setup.

6. You’re not tracking phone calls

If your primary conversion is a phone call and you don’t have call tracking set up, you’re invisible to the algorithm. Tools like CallRail or Google Forwarding Numbers connect call data back to your campaigns.

The fastest way to audit your tracking

• Install Meta Pixel Helper Chrome extension and visit your thank-you page
• Install Google Tag Assistant and check which events fire on form submission
• In GA4, check Realtime → Events while submitting a test form
• In Google Ads, check the Conversion Actions for duplicate primaries
• Compare your conversion counts month-over-month for sudden spikes or drops
