What should I know about Google proxies and flagged clicks?

A proxy acts as an intermediary for requests from web browsers, and Google has lots of proxies they use in conjunction with various Google services …

… including but not limited to Data Compression for mobile Chrome users, Google website previews, Google Translate, and Google Mobilizer just to name a few.

Here’s what you need to know about Google proxies and ClickMagick’s click auditing system:

Any time an end-user’s request is routed through Google’s proxies for any reason, Google adds an “X-Forwarded-For” header to the HTTP request which contains the user’s actual IP address.

This allows ClickMagick to grab the user’s actual IP address and process the click correctly, even though the request came from one of Google’s proxy servers.

On the other hand, if a Google proxy request does not contain a valid “X-Forwarded-For” header that means the request did not come from a real user, but rather it came from one of Google’s automated systems i.e. a “bot.”

You can identify these requests in your ClickMagick logs because the hostname for such a request will always start with “google-proxy.”

If you want us to take a look at a particular IP, just reach out with the details and we’ll be happy to take a closer look.
