Meta (Facebook) Pixel

Measure conversions and build retargeting audiences for Facebook & Instagram ads.

Premium Public page

How it works

Your Pixel ID (a 15–16 digit number) is injected as the Meta fbevents.js base code, firing an init plus a PageView on load.

Every visit becomes a signal Meta can use for attribution, Custom Audiences, and delivery optimization.

How it flows

Tips to get the most out of it

  • Create a Custom Audience of everyone who visited your page, then a Lookalike to expand reach cheaply.
  • Retarget visitors who didn’t buy with a time-boxed offer.
  • Let Meta’s algorithm optimize delivery toward people who actually engage with your page.
