What is Google tag gateway for advertisers?

Google tag gateway for advertisers allows you to deploy Google scripts using your own domain, enhancing data privacy and improving signal measurement recovery.

Before you begin

• You must have a Google Tag Manager container installed on your website.
• Sign in to your Cloudflare account and grant permissions to Google to set up Google tag gateway for advertisers.
• Enabling this feature affects Google tag firing behavior. If your current tag behavior is impacted by user consent actions, adopt Consent Mode, and review your consent settings to ensure your preferences are respected. Learn more About consent mode.
