White Hat SEO
Michael D. Crawford has a good intro to White Hat SEO. Tips include:
Use a meaningful "title".
Repeat your page title in an h1 element.
Write a killer lead paragraph, and make the same paragraph into the content of your "description" meta tag.
(I would probably add "put your best title keywords in the URL, separated by hyphens not underscores," "reduce the amount of non-link boilerplate copy as much as you can," and "make sure it validates.")
