Until now static content in SWF files (Flash Player file format) was indexed to some point by search engines like Google and Yahoo. Any dynamic content was not even close to be read by search engine, and developers worked with alternative content. Alternative content is content displayed in HTML page behind the Flash file, which containts infomation equal or similar to ones current flash page is displaying. Problem was that alternative content coudn’t be set dynamically and read by search engines as Flash file change it’s content without reloading.
Great news is, Adobe has came out with Flash Player which will be used by search engines, for now Google and Yahoo which enables them to get all content from Flash, going through it and retrieving the dynamically loaded content… You can read more at Adobe Developer Center
I think this doesn’t mean Google and Yahoo would be able to link to your dynamic pages directly, because there is no fake clicking capability in current Flash player, or time skip functionality. Something like that may be an option but for now I don’t think Google or Yahoo can lead directly to your dynamic page inside SWF but they can be aware of your content and show it in search results.
This is surely a great news, with deep linking already enabled on your site this will work like a charm surely.
Thanks Adobe… And please keep this good news coming every month!
