The biggest thing is to make your text sound natural. Emphasize with h tags here and there, use of italics if it's appropriate will also be noted and weighed. Be sure the very last line at the bottom of your page repeats your domain name, with some sort of descriptive keyword sentence on it. You can also use bold, and different fonts for effect, just don't pick something that isn't common to most computers.

NEVER obscure text by trying to make it like a hair lighter or darker than your background for color ... the SE spiders can actually determine if you're "hiding" keyword lists that way. (think that's what Ian was referring to)

If normal H1 and H2 are too big - tell your page what size you want those to be font size wise. Links that are not pertinent to your site should always be in the smallest font you use. So if your main text is say 12 pixels ... make the links out to the parental controls to like 10 or 8 pixel.

When you name your page (title) - use 4-5 descriptive words and then a | mark and then your url


Example: Hardcore Twink Movies | Mydomain.com

Your meta tag description and keywords should change for every page - utilize those words that actually APPEAR on the page itself. If you only use 4 good keywords - then use 4-5 in the meta tag - you're penalized for keywords that aren't relevant to the page/site.
