Hello,
is there any special bot that Google uses when gathering data for Pagerank purposes?
I mean main googles bot is "Googlebot", but once per few months there is Google Pagerank update, so im asking if google uses any different bot / user agent for this.
When i let Google fetch my website thru Webmaster tools i got this user agent: Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
