Here's a real world example of why article submissions can help your ranking:
A while ago, we performed a test on one of our sites. We created two pages on our site with very similar content. One page had keywords targeted like this: keyword-keyword-cityname1 and the other targeted keyword-keyword-cityname2. The keyword-keyword were identical, the only difference was the city name. On both pages we had a direct link from the main site navigation and we then linked to them from other pages on our site that related to each of them. So far, everything was absolutely identical about both pages except for the name of the city involved.
Next, we wrote an article about only one of the cities. We made sure the article was about the city in general and sprinkled in a few choice keyword references. The author box in the article had a direct link to that city page.
We monitored the search engine results closely for while. About 6 months in to the experiment, we checked our rankings and found that the page that had the article written for it was showing up as #1 when searching for its title, but the page that had no article written for it, but all else being equal, was showing up on the 4th page. This is a huge difference and verified our thoughts on article submissions.
