Hi there, I really need some help here. My website is 6 weeks old, the main keyword I'm promoting was at around position 45 a week ago, other 3 buyer keywords that were ranged from about position 8-20 without too much of linkbuilding, I also had a low search volume low competition keyword at No.1 without any linkbuilding work before. I started comment spam a week ago, I comment spam those pages that contain many spammer links, most of them had OBLs less than 100, yet some of them have more than a few hundred or even 1000+ OBLs. I put 5 links that each links to 5 pages of my website, with identical anchor text and comment words on each of these sites earlier, later then I decided to use spun article as comments. So far I've built about 20+ pr3-pr7 backlinks over the week, most of them are pr4. I found that my main keyword's position started to drop a few days ago, yesterday those buyer keywords' ranking had all dropped, now they are in position 30-60, yeasterday my main keyword was at 49, now is at 235! I also found the ranking of some other keywords that I hasn't promoted has dropped. The keyword that were at no.1 before is now at No.10. So does this mean google has detected my spammy activity and penalized my website? Or is this normal google dance for newsite? Should I continue to build such comment links? And most importantly, how to regain my previous positions...? Any info will be very appreciated. Thanks.
