I found this site that is amazing for article marketing or backlinks. It is articlelaunchandrelease.com you submit an article to the site and it gets built out over thousands of domains that they own in a network. All the domains have page rank and all the domains as a whole get about 260,000 unique visitors daily. With that amount of visitor you get lot's of traffic. There are two ways I use it one is two submit articles linking to my site for backlinks and traffic. Then the other is to submit articles that link to an article from ezine or articlebase so the backlinks drive the article up Google.
I have dozens of articles on page one of Google by doing this. They do charge two dollars per article but for just the backlinks you would pay hundreds of dollars a month that's not to mention the traffic (they do offer three articles for free). Before you start thinking that I'm trying to sell you an affiliate product just paste the URL in your browser and you will notice that they don't have an affiliate program. I hope you will find this as useful as I have.
