My site keeps getting the google dance once every 2 or so months. My traffic has been building steady over the last few weeks, up to 150 hits a day yesterday, I check today and it's off to a VERY slow start, and my rankings fell for my top keywords, and other top keywords dissapeared. The exact thing happened to me 2 months ago, and they came back stronger than ever (up to position #1 for some of my main words) So i guess I should just keep building up my backlinks, but this is so annoying! My site is not de-indexed, it still has google authority site-links. Anyone else see this?
