Anybody tried this? I found them on PRWeb this morning: http://www.prweb.com/releases/2006/1/prweb336351.htm Interesting read. They give you an seo analysis of your site that is written to teach you how to do SEO yourself. Not sure if there's much use for something like this though.
This could be OK for those who don't know much but I am sure you will get much better advice from posting your url in a forum like this. At least you can post back and ask about this things you don't understand. For every service like this that you have to pay for there is another which is just as good and free.
