TagAudit's free scan detects the Meta pixel, reads its ID from the page or from its requests to facebook.com/tr, and records whether those requests are attempted before any consent choice or after the banner's reject button was pressed, when the scan finds one. Two different pixel IDs are both listed.
What this can't tell you
- Conversions API (server-side) events. These are not visible from outside.
- Purchase or add-to-cart events. The scan's add-to-cart and place-order steps are switched off on every tier.
- Duplicate-pixel or per-event diagnostics. Not part of the report today.
