What I Learned About Conversion Tracking From My First Google Ads Campaign

Why tracking matters

Imagine that an advertising dashboard tells you that you received six conversions. You might immediately calculate your cost per conversion and start judging the campaign.

But what if only three people actually submitted the form? Now the analysis changes.

That was the situation I encountered in my practice campaign. Google Ads showed six conversions, while I could personally verify three actual form submissions. The full campaign write-up is in my first Google Ads Search campaign.

The important question wasn't "which number is right?"

The more useful question was: what event was Google Ads counting?

During the investigation, I found that the conversion setup could associate a conversion with a GA4 engagement event rather than only the actual lead submission I wanted to count.

That made me look much more carefully at how GA4, GTM, Google tags and Google Ads work together.

What I took away from it

I now see conversion tracking as part of campaign management rather than something you set once and forget.

Before trusting a conversion number, I want to understand:

• What action triggered it?
• Was that action the business outcome I wanted?
• Can I reproduce or verify it?
• Is the event firing correctly?
• Is Google Ads importing the intended conversion?

I expanded on all of this, including a set of common questions about GA4, Tag Manager and conversion actions, in why Google Ads conversion tracking matters more than I expected.

These are questions I want to keep asking in future campaigns. Working through the problem is also one of the places where AI genuinely helped me, not by fixing anything, but by helping me understand what to investigate.
