Hey, I'm still ranking for plenty of keywords on my main site, but it's disappeared from 2 keywords i was working on according to market samurai, i was 18th and 23rd (pretty competitive) now it's just gone, i've lost quite a few keywords actually. I did have some downtime on that site recently, but only 6 hours max, and it appears now those 2 keywords aren't ranking. It's been like this for 12 hours at least. What do we think? I mean it hasn't been de-indexed and everything i'm doing is white-hat, so no reason for it anyway. So Google dance? Downtime caused it? Any ideas?
