Even though flash (SWF) files have been used for creating great looking websites, the content in it was not been indexed by search engines. This trade of between user interface and searchability has been road block for developing rich internet web applications using Adobe Flash.
Now Adobe is releasing a technology to Google and Yahoo that enables them to crawl and index SWF (flash) files. That means, flash files are now made searchable. This will open up millions of Flash files to search. Any text or links in a Flash application can now be indexed. Google has already started indexing SWf files.
Adobe has created a special Flash player for the search engines that acts like a virtual user going through each application. It actually goes through the runtime of each Flash application and translates it into something the search engines can understand. [via tc]
