There are a couple of websites that let you automate the process of doing your article marketing.

Writing good content articles and submitting them to free article sites is a very powerful way to get back links back to your website and to get your name and website out there. The better the article, the more people who will use it in their blog, their e-zine or other site. 

Of course as with much of this stuff, it's time consuming to submit your articles around to all these sites, so when you want to get serious about boosting your backlinks and getting soe leverage out of what you're doing, you'll want to turn to some professional tools.

One is a desktop application that lets you submitt your article to a long list of websites, I've covered it before but it's something I use regularly so it's worth mentioning again.

The second one is a twist on the old "submit my articles" play and it combines some really nice features including a content spinner, a scheduled posting engine and a sort of "net effect" breadth of network.  Very "one touch" sorta thing, it's pretty neat.
