Obviously any system calling itself superior design must work well on not just one search engine, but should be equally well received by any and all search engines.  Any site relying exclusively on traffic from one search engine is always vulnerable to sudden algo rankings changes, competitors overtaking them etc, and is not maximizing traffic across the whole SE user-base.

A truly superior seo system will perform equally well on all the engines, anything else is, well inferior

Our own favourite superior search engine ixquick..

Yahoo..

Bing..

Dogpile..

Ask..

And finally Cuil, although this site isnt there yet, we can’t help thinking that’s a promising SE for the future, they certainly seem to be able to work out what’s what on their superior SEO listings

And finally, it should of course also be doing the same on Image search..

This is Superior SEO Domination in action…
