Adobe announced it teamed up with Google and Yahoo to make Flash websites indexable by search engines:
This announcement has been a long time coming, as Flash developers have been wishing for ways to make their content searchable for close to a decade. Adobe acknowledges this in its announcement, saying that although search engines are able to index static text and links within Flash SWF files, "[Rich Internet Applications] and dynamic Web content have been generally difficult to fully expose to search engines because of their changing states—a problem also inherent in other RIA technologies."
This announcement may also result in some major usability changes (for the better) for Flash on the web. In a post to its Webmaster Central Blog, Google wrote that it can now index all kinds of textual content in SWF files, like that included in Flash gadgets, buttons, menus, entirely self-contained Flash websites, "and everything in between." Google can now also follow URLs embedded within Flash files to add to the crawling pipeline. This new indexing technology does not, however, include FLV files (video files that are found on sites like YouTube) because those are generated as videos and don't contain any text elements like an SWF file does.
