Before I waste my time writing articles and submitting them to the various directories, I'd like to know if having anchor text link of my targeted keyword in the source box will help my page rank for those keywords?
Well as i said in another post article directories cant be a huge source of traffic. From SEo point of view also it is not a big advantage. Most high quality sites implement no follow. To not : you will be probably submitting the same article to 50 or 100 or even 500 article directories. Google pays no heed as they are just duplicate contents.
Well about your question. Yes and NO. if its a dofollow site. yes to a very small extend(<0.01%. Otherwise NO
Okay, so I have 60 unique articles. How should I go about submitting these for maximum link juice? Should I submit the same articles to several directories, or should I make a list of 30 directories and submit two articles to each one?
