where i get PR6 or above directories for free......... where i can post my link free of cost. . Thanks in advance
You can get PR-9 link at free of cost by submitting your comment here- wired.com. But the link is no-follow. You'll get good traffic from the link. ALL THE BEST!!!
A lot of people swear that getting a link on Wikipedia improves their SERPs. Nofollow and all, it still has some sort of impact. Yahoo SiteExplorer also lists a lot of nofollow pages as having backlinks to me. Point is: search engines are picking the links up, even though they may have no impact. (Google apparently says that while the links count, they do not affect the PR of the destination page. PR does not equal actual ranking as we all know, though, so there may still be some sort of positive change.) I think looking to get a nofollow on a PR6 is an unenviable undertaking. Wikipedia or Knol would be the best places to try to get a link, if only for the traffic.
