Why is it important to use Facebook Consent Mode?

While blocking Facebook Pixel scripts until a user consents is GDPR-compliant, it comes with a major downside: Facebook can’t register any interaction from users who don’t accept tracking. This means you lose valuable data on a portion of your audience—affecting ad performance, conversions, and audience insights. Facebook Consent Mode helps solve this by allowing limited, privacy-safe signals to be sent even without full consent, keeping your analytics more accurate while staying compliant.
