Pixel

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

• Advertisers place pixel code on websites or apps.
  
  
• 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.
