here's some really good articles here I just was searching and tought I would share it with every one peace out http://searchengineoptimism.com/Page_Architecture_SEO.html
Nothing that couldn't be found with a quick search around this and various other fora, although I could say that about anything because there is only so much you can talk about with SEO! Nicely laid out (different text to highlight the positioning of keyphrases). You could have pasted it here though instead of trying to increase traffic to your site.
Funny that a SEO site doesn't correctly SEO their url's. They use _ instead of - in the url. Hypocritical. They also announce using keyword fluffing in the meta keywords tag, but if you look at their page itself, they do not even do their own "techniques"
How does it matter of whether you have a (-) or a (_) if you have targeting words in the URL link itself. It would be the game for getting backlinks for that keyword which will help in trick
When you search for a keyword, do you search for: "keyword example" OR "keyword_example"? Also, that page is super ugly, and meta tags and desc. won't get you ranked in google anymore unfortunately.
