To track the results of affiliate display ads, you usually need a few basic tracking pixels. A view pixel tracks when your ad is seen. A click pixel tracks when someone clicks your ad. Most important is the conversion pixel, which tells you if someone took an action like signing up or buying after seeing your ad. Some platforms also use retargeting pixels, which help you show your ads again to people who visited your page but didn’t convert. These pixels help you measure what’s working and where to improve.
