Conversion pixel
In plain English
What does Conversion pixel mean?
A tracking pixel placed on the thank-you or confirmation page that fires when a conversion completes.
Conversion pixels are the browser-side alternative to postbacks. They are easy for advertisers to install and easy for ad blockers to stop, so they undercount. Use them for platform optimisation (Meta, Google) and postbacks for affiliate payment.
