Flash in or in place of your website
21 Jun 2008 | Angie H
Search engines are getting better and indexing flash content and there are things you can do to make the content inside flash more readily available to the engines. The answer to your question is "no" but you still have to consider carefully how to best implement flash technology into your site so it serves both your visitors and the search engines. I'll tell you this, if you are trying to optimize for a few dozen very distinct keywords, it'll be very difficult to do that with an all-flash website. When you build a site in HTML then you're able to target keywords on specific pages, creating a better focus and better opportunities for rankings. Not to mention the ability to drive the visitor directly to the content that is most relevant to their search. But that doesn't mean there are no great ways to implement flash in a website. However, flash should be an enhancement of, not a replacement for, a website.
