So i was slowly moving up on SERPS for my main keyword (was on page 3) and all of a sudden I totally disappeared from the face of the earth. Google still indexes all my pages, and send some traffic for other keywords but no listing for my main one. Also my PR dropped from 1 to 0 on January 1st Has anyone else experienced this? Will my main keyword listing come back and my pr go back? I had PR1 with no SEO and now after 2 weeks of onpage and offpage SEO i drop to pr 0?? makes no sense at all. I didn't do any black hat spamming or any sorts of that. Only a little of social bookmarking and digg, twitter etc.
