I'd generally agree with TR Brown on this — taking measures to improve your traffic via Google (and other search engines) will help. This includes raising your pages' SEO — but the frenzy now to do this has become a disease, and I'd avoid getting too carried away on this.
Pick out a keyword phrase that captures well the basic theme of your webpage, and which can also be smoothly and appropriately blended into perhaps 2-3 sentences in the content. But avoid phrases like "SEO capture" which make you contort much of your content trying to implement SEO capture by using a phrase designed for SEO capture but doesn't succeed so well in the basic SEO capture strategy of SEO capture (see what I mean?).
Also, I tend to believe that "more" is definitely better when it comes to webpages — the more good, interesting, well-produced Hub articles on the Web, the greater the chance that someone will find your pages in searches and eventually will click on an ad — IF your ads are relevant to your content.
