When doing some stuff with automated Google Admanager Ads (that required frequent updates), we realized that google is checking every link. At least once per update. Usually more often. With no proper user agent identifying it as a bot. Our solution was to redirect all links through our server and completely block every known google IP-range during the redirect.
