Pixel Definition

In advertising, a pixel is a piece of tracking code embedded in a website or landing page that collects data on user interactions, such as page views, form submissions, or purchases. Pixels enable retargeting, conversion tracking, and campaign optimization.

How Pixel Works

  • The pixel fires when users visit a page or complete specific actions.

  • Data is sent to platforms like Meta Ads, Google Ads, or analytics tools.

  • Advertisers use this data for retargeting, audience building, and conversion measurement.

Example of Pixel

An online retailer uses a Meta Pixel to track product page views and retarget users with dynamic ads on Facebook.
