It looks way too spammy, is it an SEO tool or a weight loss website?? surely they would get alot more credance making the tool look more like what it is???
Going to the search engines and typing in your keywords is the best way to see who outranks you. Have their site structure studied and you can see why they rank well.
You can also get he backlinks and analyze them using yahoo site explorer.
If it really works, it much helps us much. It's really tired and waste to check how our competitors work manually. However, usually I see them do link exchange to get back links. I want to do another way.
