KISS-Keep It Simple, Stupid... Your visitors will be interested in quality content above everything else, so as SEs. Flash and animation comes after that only. Hope that help, Edward
Time has it right. Ignore every other person here who says otherwise. PHP and ASP output data in an HTML format for web browsers and crawlers. It has nothing to do with optimizing a website. It optimizes equally as well as a flat HTML/CSS website because it will output the same format. The only addition I would add is that there is no reason to use PHP unless you have a need for CMS or something else. Several of my websites are HTML files and include no PHP except for maybe a form or something.
