What is Meta Pixel?
The Meta Pixel (formerly the Facebook Pixel) tracks visitor actions to measure and optimise Facebook and Instagram ad campaigns, build custom audiences, and power retargeting across Meta’s platforms.
Why Meta Pixel matters
The Meta Pixel is one of the most widespread — and most scrutinised — advertising tags on the web. It is a frequent subject of privacy enforcement because it commonly fires before consent and sometimes captures form data it should not. Getting it right is both a performance and a compliance issue.
Is your Meta Pixel set up correctly?
- The pixel does not fire before the visitor has given consent (a common source of GDPR complaints).
- No sensitive form fields (email, phone) are captured in automatic-advanced-matching without hashing.
- Standard events (Purchase, Lead) are implemented with values, not just PageView.
- The pixel is loaded once, not duplicated.

That is exactly what TagStack checks. Many sites load the Meta Pixel on page load regardless of the consent banner — a frequent trigger for privacy complaints. A scan shows whether yours waits for consent.
