Adobe says it’s going to “dramatically improve” the search results of dynamic web content and rich Internet applications (RIAs) for Google and Yahoo by giving them optimized Flash Player technology.

This new widgetry, which will read and index SWF files, is supposed to uncover information that is currently undiscoverable by search engines and provide more relevant automatic search rankings for the millions of RIAs and the other dynamic content that runs in Flash Player.

It also means that RIA developers and rich web content producers won’t have to fiddle with existing or future content to make it searchable.

Adobe says Google has begun to roll out Flash Player technology in its search engine. Yahoo will get around to it.

Google has always told webmasters to use Flash sparingly if they care about their page ranks because search engines are text-based. It’s still saying the same thing about Flash-based images and video.
