Re: SeoBoo.com - The way they try to promote their product puts me off from buying it completely ... Contradiction: "ONLY current SEO book on the planet", "#1 ranked SEO Book", "top spot for SEO Book on google, and yahoo" (very easy to achieve if there is no competition - if it were top spot for SEO, ok maybe then I would be impressed)
Text can have disastrous effects if you don't do it properly
"The only current SEO Book on the planet.
Buy the industry standard #1 ranked SEO Book. What do the search engines think?
Google Search: SEO Book (#1)
Yahoo! Search: SEO Book (#1)
This is the #1 ranking SEO book on all major search engines.
