Re: "I'm a SEO expert"
I see nothing they do of value
I use the graphics package Xara Designer Pro and recently received an email with an "upgrade" offer (the thing has gone partly annual-subscription now) which includes a product claimed to perform SEO on your websites, and claimed to be worth £285, completely free (the XPD upgrade is £89). I think that tells you all you need to know i.e:
One of XDP's functions is web page design. The company also produces an SEO product, claimed to be worth £285, but not actually listed in their main products page and appears not to have a separate product page at all so there's no information on what, exactly, it does. In order to get it used by real people they have resorted to giving it away.
