Google has introduced Google Tag Gateway for advertisers in beta, allowing integration with Fastly through Google Tag Manager. This setup enhances data privacy by enabling the deployment of Google tags using custom domains and improves measurement accuracy.
To configure, advertisers must log into their Fastly account, set up the Google tag gateway in Tag Manager, and follow specific steps to activate their website domains. The setup’s success can be validated using Tag Assistant, ensuring correct functionality.
