Conversion Pixel
Invisible tracking snippet that measures whether a click turned into a sale or lead.
A conversion pixel (also called a tracking pixel) is a tiny snippet that ad platforms like Meta, TikTok, and Google embed on a page. When a visitor loads that page, the pixel fires an event back to the platform, which then ties the event to the ad that drove the click.
Concrete example: you run a Meta ad for an online course. When someone clicks the ad, they land on your sales page where the Meta Pixel is installed. If they buy, the pixel fires a Purchase event. Meta learns which audience actually buys and optimizes your ad delivery against that signal.
Affiliate marketer trick: instead of linking directly to the vendor's checkout, route traffic through your own promolinks.net short link with your Meta Pixel installed. You build a retargeting audience from everyone who clicked the affiliate link — even the 95% who did not convert on the vendor's page.
