What is happening, I have received 80 stumbles and 9 diggs in the past 24 hours due to a PR, now the site has dropped to page 3 from mid page 2, WHY?
Just because you're getting Social Bookmarks doesn't mean that it will help you rank a lot, Stumbles and Diggs generally don't have that much effects. Its probably just a coincidence you've noticed. What you need to do is build backlinks to those pages in order to keep them ranking high.
