Ad Pixel

Reading

A Facebook pixel is a small piece of JavaScript code that an advertiser places on every page of their website. This piece of code provides a set of lightweight functionalities for sending user-specific events and event-specific custom data to Facebook. Advertisers can use the Facebook pixel to capture intent information about how people are using their website. A single Facebook pixel is added to all pages of a website, and is then used to create website custom audiences
