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.

Seo Master present to you: My favorite part about Google I/O is the dozens of interesting conversations with developers -- getting a first-hand look at the different things that they are doing with our technologies. That's the spirit of the Google Technology User Groups -- regular meetups where local developers can get together to network and discuss, demo, and hack on Google's many developer offerings.

From lightning talks in Mountain View, to App Engine hackathons in Tokyo, to lectures in Berlin, the GTUGs are a great place to meet fellow developers and learn (or teach) something new.

At Google I/O, there were many folks eager to bring the spirit of the conference back to their hometowns by starting up GTUGs of their own. Since the conference ended, our list of current GTUGs has grown to include this 'baby boomer' generation of chapters. The following are all new groups looking for members and starting to set up their first events.

If there's one near you, check it out! Let the organizers know you're interested; suggest topics for discussion and even offer to do a talk about your own experiences.

We'd like to highlight three best practices that address some of the most common problems found when crawling and indexing video content. These best practices include ensuring your video URLs are crawlable, stating what countries your videos may be played in, and that if your videos are removed, you clearly indicate this state to search engines.

• Best Practice 1: Verify your video URLs are crawlable: check your robots.txt
  
  • Sometimes publishers unknowingly include video URLs in their Sitemap that are robots.txt disallowed. Please make sure your robots.txt file isn't blocking any of the URLs specified in your Sitemap. This includes URLs for the:
    
    • Playpage
      
    • Content and player
      
    • Thumbnail
    More information about robots.txt.
    
  
  
• Best Practice 2: Tell us what countries the video may be played in
  
  • Is your video only available in some locales? The optional attribute “restriction” has recently been added (documentation at http://www.google.com/support/webmasters/bin/answer.py?answer=80472), which you can use to tell us whether the video can only be played in certain territories. Using this tag, you have the option of either including a list of all countries where it can be played, or just telling us the countries where it can't be played. If your videos can be played everywhere, then you don't need to include this.
    
  
  
• Best Practice 3: Indicate clearly when videos are removed -- protect the user experience
  
  • Sometimes publishers take videos down but don't signal to search engines that they've done so. This can result in the search engine's index not accurately reflecting content of the web. Then when users click on a search result, they're taken to a page either indicating that the video doesn't exist, or to a different video. Users find this experience dissatisfying. Although we have mechanisms to detect when search results are no longer available, we strongly encourage following community standards.
    
    To signal that a video has been removed,
    
    1. Return a 404 (Not found) HTTP response code, you can still return a helpful page to be displayed to your users. Check out these guidelines for creating useful 404 pages.
       
    2. Indicate expiration dates for each video listed in a Video Sitemap (use the <video:expiration_date> element) or mRSS feed (<dcterms:valid> tag) submitted to Google.
