Google's ad and tracking domains are mostly exempt from the Great Firewall: www.googleanalytics.com is not blocked ( https://en.greatfire.org/https/www.googleanalytics.com https://en.greatfire.org/https/www.googleanalytics.com ) while googleads.g.doubleclick.net was apparently blocked for a while but is currently accessible ( https://en.greatfire.org/https/googleads.g.doubleclick.net https://en.greatfire.org/https/googleads.g.doubleclick.net ) EDIT: I just noticed that Gwern's article includes the URL of the ad script he embedded: pagead2.googlesyndication.com/pagead/js/adsbygoogle.js. That one's not blocked either ( https://en.greatfire.org/https/pagead2.googlesyndication.com/pagead/js/adsbygoogle.js https://en.greatfire.org/https/pagead2.googlesyndication.com... ) What tends to break sites is when they depend on ajax.googleapis.com, which has been blocked for years now ( https://en.greatfire.org/https/ajax.googleapis.com https://en.greatfire.org/https/ajax.googleapis.com )
