Does the _fbc cookie require consent?
_fbc is used for advertising, so under the GDPR and the ePrivacy rules it may only be set after the visitor has agreed. Showing a banner is not enough on its own: the cookie must not be set before the visitor clicks accept.
Does your site set _fbc before consent?
A free scan loads your site the way a new visitor sees it and lists every cookie that is set before anyone has said yes, _fbc included.
How to put _fbc behind consent
Remove the Meta Pixel snippet from your site and add your Meta Pixel ID under Integrations in Consentify instead. Consentify then loads Meta Pixel only after the visitor has accepted advertising, so _fbc is never set before consent.
