AdsBot-Google is a bot in the advertising and marketing bots category, operated by Google. Google AdsBot is special-case crawler that monitors websites where Google Ads are served.
We have not confirmed whether AdsBot-Google follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.
Add "User-agent: AdsBot-Google" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "AdsBot-Google" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so AdsBot-Google may not follow it, and anyone can send AdsBot-Google's user agent, so a fake AdsBot-Google ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
Run a reverse DNS lookup on the IP. Genuine AdsBot-Google IPs resolve to a hostname ending in google.com, and a forward lookup of that hostname returns the same IP. Anything else using its user agent is an impersonator.
