I'm not making this post to moan, I know that being liked by Google is sometimes a hard task and it can get on one's nerves.
I'm rather seeking advice on what to do and what you think is going to happen next.
The site I'm talking about was #8 for its main keyword and ranked pretty well for other long tail keywords. It was getting about 150 UVs per day, until yesterday.
It is now nowhere to be seen in the first 150 results on Google for the main keyword. Also, its rankings dropped drastically for the other keywords it had been getting traffic from. Now I get about 10 UVs per day.
However, none of the pages of my site got de-indexed, when I put site:mysite.com, it still shows that all pages are indexed.
What I've been doing recently with the site is, I've been making a post per day, I also picked the older posts and submitted them to article directories (one per day) with no changes, linking to the related post, plus I was creating my own articles, span them and submitted them to article directories and web 2.0 sites. I've also been building backlinks via profile and signature links and blog commenting. All that I did manually, about 20 links per day, do you think this could affect the rankings?
Or could this be the so-called Google Dance, and how long it may take for my rankings to come back?
