Today I found several site talking about SEO of flash movie. The main idea is that Adobe, Google and Yahoo! are trying to enhance the searchability of swf file. However, it seems it is still early for us to find a suitable swf from search engine now. Most people are now using the SWFObject or UFO instead of traditional <embed> or <object> tag to replace the text content by the swf into the html. So that the search engine can still recognize the original text content. The following are the reference talking the flash SEO.
