The Facebook Pixel is a code on your website that tracks user actions to help measure and optimize your ads. It lets you:
1. Retarget visitors based on actions they take.
2. Reach people likely to take key actions (like donating or buying).
3. Measure ad performance.
To use it, add the pixel code to your site’s pages. It tracks user actions and sends data to Facebook for better targeting and retargeting. The Pixel Helper Chrome tool helps troubleshoot if it’s working correctly.
