The fact some site enjoy great rankings is an illusion. Ever consider there were many Panda site blasted into smithereens? I'm sure we all realize this fact. The fact is I have a site that has been sunk into oblivion for over a year. Perhaps year and a half and it did pop up to page 1 ranking. Nothing was done to the site in a year, no special link building etc. Essentially dormant for months and months. I have to assume Panda is related to this. It was deader than a door nail. It's not like it got better to get rankings.
