I have 2-3 main sites going for couple years now. I haven't touch IM for almost a year. But before that, my sites gets plenty of backlinks from AMR, Senuke, Scrapebox, and some High PR blogs on BHW. Lets say I target keyword: "weight loss" for the main site and 1-2 pages. It was on page 1 position 2-7. After 1 year now I check, all the pages and main sites that I spent my money on are all gone. Accept 1-2 pages that has absolutely no backlinks on it are still on page 3-4. Can someone explain this? I've been gone so long I need to update. Is this normal?
