A comparison of three article submission services

Just a note on where the various submission services are at -

From Organic SEO:

Article distribution is one method of gaining links to your website. Although it is not near as effective as it was in the past it can still be worth the time. One of the most difficult aspects of using articles for SEO is getting the articles distributed on the right websites. We tested 3 different services, you can see the results after the first 22 days in this post.

Background
We used three different articles for the same website and distributed them using three different article distribution services. Although the articles were different all-in-all this should be a good indicator as to which service performed better. To analyze the results we took 5 different unique sentences in the article and searched for that specific phrase in Google and Yahoo. Different sentences bring back different results; that is why there is a range of pages indexed.

#1 Article Marketer
Service Level - Free
Date Article Distributed for SEO: April 25th, 2007
Google - pages with the article indexed: 0
Yahoo - pages with the article indexed: 0
Overall - What can I say more? This one is out of the question. I doubt even their paid service is much better.

#2 iSnare
Service Level - Paid $10 (for 5 articles)
Date Article Distributed for SEO: April 25th, 2007
Google - pages with the article indexed: 120-217
Yahoo - pages with the article indexed: 38-70
Overall - iSnare seems to be pretty good, and it is extremely inexpensive. The articles did get distributed to many pages in just 30 days, although some of the pages were extremely low quality they are just as good as the competition.

#3 The Phantom Writers
Service Level - Paid $35
Date Article Distributed for SEO: April 30th, 2007
Google - pages with the article indexed: 1-3
Yahoo - pages with the article indexed: 3
Overall - This service distributes the article on Yahoo message forums. There were only a few pages that picked it up so far and they were not of the best quality. It seems to be ok, but I think there are better options out there. We will have to wait another month and re-analyze the results to see if it is worth it or not.
