What is Pixel? Tracking pixel explained

A pixel is a snippet of code on your website that reports visitor actions — page views, add-to-carts, purchases — back to an ad platform.

Example

The Meta Pixel on a thank-you page fires a Purchase event with the order value.

Why does Pixel matter for e-commerce?

Pixels power optimization and retargeting, but browser restrictions mean they miss some events; pairing them with a Conversions API closes the gap.
