Unfortunately, most spider-based search engines do not read Flash®, so using Flash animation on a website will not help improve the site's search engine ranking. If you are submitting pages that are partly Flash-animated, optimize the page's Meta and Title tags, and add well-composed and keyword-rich page copy.
Because search engine spiders cannot read Flash, crawler-based search engines will detect no links created with Flash. For search engine positioning purposes, regular HTML hyperlinks therefore are considerably more effective than Flash-based links. However, by incorporating both solutions — an HTML and a Flash version of each page link — on the same page, Flash animation can be retained without crippling visiting spiders.
