None that I'm aware of.
Upon receiving my web analysis, it immediately told me how to fix and optimize my website, unlike most of the other SEO software out there failed to do. Finally, I had an easy to read and easy to follow set of directions on exactly how to fix my sight.
If all they provided was the web analysis I would have gotten my monies worth, but on top of it they sent me a detailed 20 page report on the exact search engines they submitted to. Thanks guys for your great service!
