Well, there is another concept I have been playing around with which has proven to be extremely powerful as well: inner linking.
Basically, when you link within your own site/blog (from one page to another), use anchor text with the keyword you have optimized the page you are linking to with.
It's the same principle as anchor text backlinks, but within your site. And I bet most of you are not doing it.
Don't question me, just give it a shot and check your SE rankings a month later.
