I have below 20 of the PR5 article directories that have a Page Rank of 5. Posting articles in an Article directory is a great way of getting quality anchor text backlinks and a boost of traffic to your site. These article directories are very good and are not spams. Spammy Article directories will not help you very much interm of SERP. Make sure you submit your article uniquely to the directory, don’t submit the same article to all of them.
