I added one of my autoblogs to Google Webmaster tools by mistake (was adding a lot of sites, slipped off my mind that this one was an autoblog). Within a day of adding it to Webmaster Tools, my ranking dropped significantly (from #15 to #751). Its been a week since, so its not a case of Google Dance. I removed the site from Webmaster tools almost a week ago, but the ranking is still hovering around 750. What can I do to mitigate this and get my site back up the SERPs? This was a great niche and the site was picking up momentum - would've broken through to the top 5 if I had continued my backlinking strategy (there are over half a million searches for my keyword). Any SEO experts care to shed some light on this?
