Advertising & PixelsWhat is Google Ads Conversion Tracking?
Google Ads Conversion Tracking measures the actions people take after clicking a Google ad — purchases, sign-ups, calls — and reports them back to Google Ads so the platform can optimise bidding toward conversions.
Why Google Ads Conversion Tracking matters
This is one of the most common advertising tags because conversion data is what powers Google’s automated bidding. When it is broken or double-counting, you are not just losing reporting accuracy — you are actively misleading the bidding algorithm and wasting spend.

Is your Google Ads Conversion Tracking set up correctly?
- The Conversion Linker tag is present — without it, conversions lose attribution after the click.
- Conversion values are passed dynamically, not hard-coded to a single amount.
- Each conversion fires once per action, not on every page load (a classic over-counting bug).
- Consent Mode is active so conversions are modelled correctly when consent is denied.
