Tracking Pixel
A snippet of code placed on your website to track visitor behavior for ad targeting.
Why It Matters
Without a tracking pixel, you cannot measure conversions or build retargeting audiences.
How It Works
The pixel fires when a page loads, sending data back to the ad platform about user actions like page views, add-to-cart, or purchases. This data powers optimization and audience building.
Real-World Example
The Meta Pixel tracks a purchase event and reports back to Facebook that a conversion occurred.
Common Mistakes
Installing the pixel but not verifying events fire correctly
Placing the pixel only on the homepage

Tracking Pixel FAQs
Do I need a different pixel for each platform?
