What a feeling! Even better indexing of SWF content
Thursday, November 11, 2010
Webmaster Level: All
We often get questions from webmasters about how we index content designed for Flash Player, so we wanted to take a moment to update you on some of our latest progress.
About two years ago we announced that through a collaboration with Adobe we had
significantly improved
Google’s capability to index Flash technology based content. Last year we followed up with an announcement that we had added
external resource loading
to our SWF indexing capabilities. This work has allowed us to index all kinds of textual content in SWF files, from Flash buttons and menus to self-contained Flash technology based websites. Currently almost any text a user can see as they interact with a SWF file on your site can be indexed by Googlebot and used to generate a snippet or match query terms in Google searches. Additionally, Googlebot can also discover URLs in SWF files and follow those links, so if your SWF content contains links to pages inside your website, Google may be able to crawl and index those pages as well.
Last month we expanded our SWF indexing capabilities thanks to our continued collaboration with Adobe and a new library that is more robust and compatible with features supported by Flash Player 10.1. Additionally, thanks to improvements in the way we handle JavaScript, we are also now significantly better at recognizing and indexing sites that use JavaScript to embed SWF content. Finally, we have made improvements in our video indexing technology, resulting in better detection of when a page has a video and better extraction of metadata such as alternate thumbnails from Flash technology based videos. All in all, our SWF indexing technology now allows us to see content from SWF files on hundreds of millions of pages across the web.
While we’ve made great progress indexing SWF content over the past few years, we’re not done yet. We are continuing to work on our ability to index deep linking (content within a Flash technology based application that is linked to from the same application) as well as further improving indexing of SWF files executed through JavaScript. You can help us improve these capabilities by creating unique links for each page that is linked from within a single Flash object and by submitting a
Sitemap
through
Google Webmaster Tools
.
We’re excited about the progress we’ve made so far and we look forward to keeping you updated about further progress.
