Using flash is a designer's dream, for the control you have designing a website, but much is lost for search engine optimization. Flash animation has it's place but not for a website. Using Flash as a website prevents search bots to index your site, which means all the text you have is not indexed.

It's important that you have the correct meta tags created for you site. There is much discussion on what work's and what doesn't, you should do your research or hire someone to do it for you correctly. I would also recommend Google Sitemaps and Analytics to build a bridge with Google for indexing. Content management systems have really increased the ability to optimize SEO.

It's highly recommended that you ditch the flash for a website. You should your business using the newest technologies that are available. Flash Animation can be expensive, but it can be more costly if you have to have your site redone. I have had clients experience this personally. It's about your return on your investment and that is what Global OUTage is all about.
