Google and Yahoo! to index Flash for search
Monday, July 7th, 2008In the not so distant past, web developers who used Flash had a major pet peeve: search indexing. Search engines like Google and Yahoo could not index content coded in Flash. Developers using the Adobe plug-in were forced to use any number of inventive techniques to ensure their content could be found by search users, including creating HTML sites to mirror their Flash work. A recent announcement has changed this, though, and developers are thrilled that their Flash content no longer needs to be presented in more than one way.
Last week Google announced that they had developed a new method to index Flash. As an official blog post explains, “Now that we’ve launched our Flash indexing algorithm, web designers can expect improved visibility of their published Flash content, and you can expect to see better search results and snippets.” The Searchable SWF integration, as it’s called, allows the search engine to explore Flash files in the same way a user would. Information and content keywords can be stored and indexed through the new algorithm, freeing developers to worry only about the effectiveness of their applications.
The indexing of Flash files was made possible partially because of Adobe’s new Searchable SWF library. Google was able to draw on this resource in building their own technology for Flash search. With Flash and rich content becoming more and more pervasive on the net, search engines have struggled to keep up with the need to make these applications searchable for users. The collaboration between Google and Adobe has made it possible for both users and developers to have a better search experience. An Adobe press release points out, “As a result [of the team effort], millions of pre-existing RIAs and dynamic Web experiences that utilize Adobe Flash technology, including content that loads at runtime, are immediately searchable without the need for companies and developers to alter them.”
Yahoo! is also working to utilize the Searchable SWF library for indexing Flash content. Though they have not yet announced details, the team at the 2nd largest search engine has plans to incorporate rich content into search results in the near future.
While the move is good news for both designers and end users, the algorithm is not yet perfected. Only certain types of Flash content can be indexed with the new technology. Google will index text that appears within Flash content, and Flash text can be used for the summary that appears beneath the link in Google’s search results. Flash text can also act as keywords, and content on buttons and menus will be included in this. Links within rich content will also be indexed. However, Flash content that is not text, such as photos, images, or non-text links, will not be indexable.
So what action should designers and developers take to ensure their rich internet applications can be seen by search engines? Google’s Webmaster Central blog answers: “Basically, you don’t need to do anything. The improvements that we have made do not require any special action on the part of web designers or webmasters.” The search indexing will automatically begin on Flash content, with a few limitations (bidirectional text, such as Hebrew or Arabic, is still giving them trouble). Comments on the blog entry also ask about Flash content in Google Analytics, mirror sites created in HTML being penalized, and Silverlight indexing. On the whole, however, developers are excited for the change and ready to see their hard work popping up in search results.
