Iam trying to rank better for a competitive keyword with 33.000 exact searches currently I am on 5th page. So far I did article submission blogs and xrumer profile blasts. Thinking about getting a linkwheel but not sure if they are safe or not. I read about close and open linkweels not sure which is better, also how big should they be? Please advise what?s the best strategy for linkwheel and if they are still effective. Or maybe I would be better getting 5 2.0 sites putting article on them linking them to my site and spamming them with scrapebox and profile blasts?
