advertisers. We recommend Google tag gateway for advertisers for the most
durable tag configuration.
Overview
Google tag gateway for advertisers lets you deploy a Google tag using your own
first-party infrastructure, hosted on your website's domain. This infrastructure
sits between your website and Google's services. The setup in this documentation
will help you better measure your website. You can set it up using your existing
content delivery network (CDN), load balancer, or web server.
In standard Google tag setups, your web page requests a Google tag from a Google
domain. When the tag fires, it sends measurement requests directly to the Google
product. With Google tag gateway for advertisers, your website loads the Google
tag from your first-party domain. When the tag fires, some measurement requests
will be sent to Google using your first-party domain.
