The Great Firewall is one of the world’s most sophisticated censorship systems, enforced by the People's Republic of China. It prevents users in China from accessing a list of prohibited foreign websites, which includes Google Search, Facebook and Twitter.

Well, in a way. The Great Firewall won’t prevent data from being collected from your website and being sent to GA, but you won’t be able to view the GA reporting user interface (UI).

According to greatfire.org, a website that monitors internet censorship in China, the resources for loading GA are not blocked, and if you’re loading it via Google Tag Manager, that should be fine as well. However, analytics.google.com is prohibited, meaning it’s not possible to use the GA reporting interface in China.

As well as the sites above, some other services sitting on the google.com domain are also blocked, such as Data Studio and Optimize.

Advertising features

GA Display Features enables data collection for Display and Search Remarketing by sending a request to stats.g.doubleclick.net, which is currently blocked in China. If your website is in China, we recommend disabling these Advertising Features.
