Google crawls 1.000.000.000.000 URLs
Oh dear. According to the google blog they have crawled over 1.000.000.000.000 webpages. Yup more then a trillion webpages. Ain’t that something? Mind you Google doesn’t count links that lead to the same webpage so these are unique pages. Furthermore they don’t follow up on calendar links so these also don’t count in the trillion pages they crawled. Not all pages are indexed though. Some pages are too similar or contain autogenerated content and these are considered unuseful for searchers.
