Good Web Based SEO Tool?

Hi guys,

looking for a decently priced, reliable SEO web-based tool to help get my sites up there.

Any info or reviews greatly appreciated.

Actually, I would be very interested in this information as well. I always wonder if any of the available "tools" do anything aside from submit sites to search engines? I mean, it takes 30 seconds to submit a site to google, and it works. What can a SEO do beyond that though?

*I should clarify, I mean that it takes a person 30 seconds to manually add a site to Googles list/database, and if we can do that manually and for free, why pay some company to do it for us?*

Obviously a sites meta data is very important.

Rankings depend on other parameters, like traffic, whether or not they are paid results... or at least, that was my impression.
