SERPs updates are happening almost everyday , can somebody tell me what's the first data center that is updating?! If I will add today 200 back links for a website, with a specific keyword in the anchor, what will be the first data center where I could see myself ranking?
Unfortunately the system does not work that way. At any one time many googlebots/spiders are active, controlled from many different servers and server farms. When a server collects new information it shares it with other servers and server farms. So one server could get updates A B C D E in that order while another server gets D A E B C. That's the dumbed down version. For a more complete and accurate description watch this video. http://www.uwtv.org/programs/displayevent.aspx?rID=3898
