I had a 6 month old EMD. no seo done to it at all. never checked its rankings. 2 weeks ago, I ordered 40 high PR links from hpbacklinks. these are all PR3+ with high DA. all links are live and have been indexed. In addition, I built some contextual links to it user SER. but I didn't do it slowly, I did like 200 at one time. I keep checking rankings every day, and my EMD is nowhere. I went all the way to page 40, and the search results end there. Site is still indexed though. Any idea what happened here? should I wait more or cancel the homepage backlinks? should I build more SER links? blog comemnts? is my domain penalized? should I forget it and start with a new one?
