Tracking Pixel
A tracking pixel is a tiny, often invisible image or snippet of code embedded in a web page or email that records when it loads, signaling an action like a page view or open. Pixels are widely used for analytics and ad measurement and are subject to consent rules.
When the pixel loads, it sends data back to the server that hosts it, allowing the owner to count events and attribute behavior.
Because pixels frequently send data to third parties, they are a focus of privacy regulation and consent management, and many teams are moving toward server-side collection for better control.
