The piece of code you install on your website to track what people do after clicking your ads. It fires events back to Meta so the algorithm can optimize delivery and you can measure conversions. Your pixel needs to be set up correctly or nothing else works.
Key Pixel setup requirements:
- Install base Pixel code on every page
- Configure standard events (PageView, ViewContent, AddToCart, Purchase)
- Verify installation with Meta Pixel Helper Chrome extension
- Test event firing with Events Manager
