What is Pixel?
A pixel is a small piece of code (often a 1×1 transparent image) placed on a website to track user activity, such as page views, conversions, or behaviors. It sends information back to the ad network or analytics platform. Pixels help advertisers measure campaign performance, retarget users, and optimize ads.
Common types include tracking pixels, conversion pixels, and retargeting pixels. They’re essential for data-driven marketing and ensuring ads reach the right audience effectively.
