Writing and submitting articles is a great way to gain high quality backlinks to your site. However, many directories are not worth the time it takes to submit to them; they might be penalized in the search engines, have author links set to nofollow or maybe they have stopped updating their site and never approves new submissions. Here is a list of some of the top article directories that are worth submitting to. The list is ordered by Alexa traffic rank.
