Hi, 2 months before i purchased a domain and was targetting 6 long tail keywords(weight loss niche). The competation was mild. I was on page 2 for all the keywords since last 2 months. Yesterday the rankings dropped to Page 20-30 for all the keywords and today they are nowhere in the top 1000 results. I didn't do much seo for all these pages. 1 month back i only created few backlinks to all these pages. 1. 25 Manual blog comments to each page. 2. Create 5 web 2.0 links from wordpress,insane journal,live journal, weebly and tripod. 3. Last week i made a few backlinks from forum posts. I don't know what went wrong but all pages have disappeared from the search results. I checked whether the website is deindexed and it is not. Please suggest what steps needs to be taken in order to get rankings again.
