So today i checked one of my site, and i found i got 30 IP from start January 10 till this morning, actually, my site got around 250+ unique IPs per day in the past, so what happened? I googled my site, it is still got indexed, maybe all of my longtail keywords droped from the SERP? One more thing, my site has very few links, less than 30 totally, some blog comments(real), some are high PR bookmark, that's all! So anybody else experiencing this ?!?!?!? I need your advice on this, Google recently update their algo?! I don't think this is dance or sth, more than half a month already !
