Tricks that I know:
ALWAYS Use H1 tags - even if you use CSS To manipulate it (like the Image-Replacement teqniques) - Google LOVES H1 Tags!
Structure over style: Search Engines love small html pages - make sure to have your CSS Create the style and don't skimp out on the H1, H2, H3, P, and Use Lists (UL, OL) as your Navigation.
The more dynamic your sites content is - the more often search engine spiders will hit your site.
Meta Tags: USE THEM and Use Them Wisely
That's just what I've learned so far.... I will give more info on Landing pages (fake SE Collection pages) when im sober enough to type
