Conversion measurement checklist
Steps to verify that Pixel, CAPI, GTM, GA4 and Ads conversions are working correctly before you spend money on ads.
If the measurement is wrong, the advertising budget is wasted. Go through this list once before launching or scaling up the campaign.

Warning
Don't spend aggressive advertising until the measurement is clear. First verify that 10–20 actual conversions are coming in correctly.
