The thing to keep in mind is search engine’s are just computer programs. They can’t see your flash intro or giant images so you need to ensure that the content you want index in major search engines is displayed clearly on your site using HTML. This is not to say you need to make your website as simple as mine it’s just to say you need to find a proper balance of imagery and text. With the help of CSS you can find that you can still have a  very good looking site while keeping the basics HTML elements in tact.
