Maybe it does what they say, but it probably does a crummy job of it. And paying anyone to do the things they advertise is an absolute waste of money. They don't even offer any pricing information on their site. You probably have to do their "free" diagnosis, plus give them your name and your email just to get any pricing. That just screams scam to me.
To be frank (and no offense), it looks like its a service for people who don't know any better. We can help you do the same things they "say" they do... and we don't charge you or sell your identity to surveys, advertisers, or others.
