If you are looking for ways to increase organic traffic to your site, you have probably heard about the importance of link building.  Each link counts as a popularity vote, with links from authority sites carrying more weight.  I have read all kinds guides and tried dozens of link building strategies, but I spend my time on just the ones that work.  I am sure that the different strategies can work, but I didn’t have luck with all of them.  I stick with posting comments in forums and on blogs and I submit tons of articles with anchor  text links to the article directories.
