Tracking pixels (or web beacons) are a fact of life on the modern web. They’re on the websites you visit, they’re in the apps you use and, most likely, you’ve placed a couple yourself. But knowing about tracking pixels is different than knowing how they work and, like lots of other tools, it’s easy to get along without actually understanding how they work.
That being said, there are as many tracking pixels out there as there are grains of sand on all the planets in the universe (or there about), and I can in no way provide a detailed explanation of how they all work. What I can do, however, is give you the basics of how tracking pixels work.
