SEO & MARKETING-ONLINE: Don't write Flash-only sites (AVOID)
If you're going to use Flash on your site, you must have an HTML version that displays when Flash is enabled. It can be tempting to put in just a single line or two of HTML as your non-Flash alternative, after all, you've done so much work on the Flash site. But since the search engines( SEO ) only see the HTML, that's what they'll rank, and you won't rank high with just a tiny version of your site in HTML.
If you must use Flash as your site, and you want to rank well in search engines( SEO ), you need to be prepared to write your site twice - once in Flash and once in HTML. --- MARKETING-ONLINE
