iowarth has said it more simply than literally of hundreds of posts on this and other forums, in many threads. Most are concerned with whether the SEO is white, gray, or whatever; those rich in content are white, and rule, or will when the algos are finally right, and the black hatters are banished (they'll go to the same place as the pushers of soft campaign funds and pork barrellers, ha, but I wouldn't advise investing in real estate there just yet). So the story goes. None consider no hat though - the sorts of sites iowarth is referring to, the true "content is king" sites. Yes, they will rank high using scientific terms - compare a google search on "fly eye morphology" "fly eye design" and "fly eye shape" - but as the example shows, fail pretty badly when more common terms are used. "Spring travel", by itself, could equally refer to vehicle engineering or vacations. On SEs, it clearly refers to commercial travel sites, with one exception on G - a commercial stock car parts site. I'll bet there are some wonderful websites out there talking about the mechanics of spring travel, and other spring information. But, no SEO, no SERP position.

If content is King, it's like the king in chess - something to be proteccted, and rally round, but without much power; you have to have it, but the game is won by other pieces on the board. However, when it is taken away, the game is lost. Sad, but true, and hopefully this analogy won't predict the future of the web.
