I read an article that th3j35t3r (hacker alias) had written awhile ago and could not find it again to reference so I will do my best to explain correctly. An anonymous individual tried to dox th3j35t3r. Th3j35t3r replied with a post to his website wherein he unmasked the Anon and explained that he did so by performing forensics on "Google search." He saw that a majority of the queries to Google for "th3j35t3r" came from a single IP address, did his due diligence and identified the person. My question is: how did he do that or what are ways to do that?
TLDR: If I had a term or phrase, what techniques could be used to get info on its queries on search engines like Google?
