Why is it important to use Google Consent Mode v2?

Using Google Consent Mode v2 is important because it helps you stay GDPR-compliant without losing valuable data. If users decline consent and you fully block Google tags, you won’t see any activity from those users — leading to incomplete analytics and reduced ad performance. Consent Mode v2 allows privacy-friendly signals to be sent even without full consent, so you can keep your data more accurate while still respecting user choices.
