Meta Pixel detected in 430,817 GTM containers in our index — and a large share have at least one setup issue.
What the Meta Pixel check looks for
- 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.
