Sending Video Sitemaps Q&A holiday cheer

Webmaster Level: Intermediate to Advanced

To the fabulous, savvy audience that attended our Video Sitemap webinar several months ago, please accept our re-gift: a summary of your questions from the Video Sitemaps Q&A!

To those who were unable to attend the webinar, please enjoy our gift of the summarized Q&A -- it’s like new!

Either way, happy holidays from all of us on the Webmaster Central Team. :)

Our entire webinar covers the basics of Video Sitemaps and best practices -- nearly everything you’d need to know when submitting a video feed.

1. Can the source/content of the video (perhaps a third-party vendor) be hosted on another site? For example, can I host my videos on YouTube and still be eligible for Video Search traffic?
   
   Yes, you can use a third party to host videos. Only the play page--the URL within the <loc> tag--needs to be on your site. <video:content_loc> and <video:player_loc> can list URLs on a different site or subdomain.
   
   For example, here’s a snippet from a valid Video Sitemap that shows content hosted on a different subdomain from the play page:
   
   

   <url>
     <loc>http://www.example.com/videos/some_video_landing_page.html</loc>
       <video:video>
         <video:thumbnail_loc>http://www.example.com/thumbs/123.jpg</video:thumbnail_loc>
         <video:title>Grilling steaks for summer</video:title>
         <video:description>Alkis shows you how to get perfectly done steaks every time</video:description>
         <video:content_loc>http://video-hoster.example.com/video123.flv</video:content_loc>
         <video:player_loc allow_embed="yes" autoplay="ap=1">http://www.example.com/videoplayer.swf?video=123</video:player_loc>
       </video:video>
   </url>



2. If I’m using YouTube to host my videos, can Google verify that I’m the legitimate owner?
   
   Currently, there doesn’t exist functionality that allows you, as the uploader, to verify that you’re the owner of a video. The issue of authorship is a hard problem on the web, not just for videos, but nearly all types of content.


3. Because Google owns YouTube, should users who embed YouTube videos still submit Video Sitemaps or is it unnecessary?
   
   Google treats YouTube as just another source for video content -- though you don’t need to submit a Video Sitemap if you only want your YouTube-hosted videos indexed. If, however, you’re using YouTube as a online video platform (i.e., with play pages on your own site), then we do recommend Sitemap submission.


4. How long does it take for Google to accept and verify a Video Sitemap?
   
   Video Sitemap submission is a two-part process:
   
   
   
   1. We fetch the Sitemap and parse it for syntax errors. This happens within minutes.
   
   
   2. We fetch the assets referenced in the Sitemap, perform checks, validate metadata, do more cool stuff, and last, index the video. This step can require varied amounts of time depending on your site and our system load.
   
   
5. What tags and categories are most important in Video Sitemaps or mRSS? Should I create my own categories or is there a list that I should conform to?
   
   Currently, the most important metadata to include is title and description -- both are required. The category tag is optional, and there isn’t a list from which to select.


6. Do I have to use HTML5 to use Video Sitemaps?
   Does HTML5 help with discovery?
   Or, if my site is HTML5 compliant, do I still need to submit a Video Sitemap?
   
   None of the Video Search principles change with HTML5. We still recommend using a Video Sitemap regardless of the markup on your site. HTML5 can be helpful, though, because tags like <video> make it easier for our systems to verify that video exists on the page.


7. If I use an iframe rather than embedding my videos, can Google still find it?
   
   We do not recommend using iframes to embed video content on your pages.


8. Can I have multiple videos on one URL?
   
   You can. We’ve found, however, that users may not consider it the best experience. When users click on a video search result, they most often don’t like being forced to locate the correct video among multiple videos on the resulting page.


9. Do I need to specifically create a robots.txt file that allows Googlebot, or do I just need to make sure Googlebot isn’t blocked?
   
   Just make sure that Googlebot isn’t blocked.


10. I provided a thumbnail, but it’s not being used. Does Google create their own thumbnails from my videos?
    
    We try to use the thumbnail you provide if it’s valid. If not, we’ll try to generate a thumbnail ourselves. We recommend that you provide thumbnails that are at least 120x90 pixels. We also accept many thumbnail formats, such as PNG and JPEG.


11. Any video filesize limitations?
    
    At this time, there aren’t video filesize limitations on content submitted through VIdeo Sitemaps.


12. Is there any way to indicate a transcript or closed captioning for a video?
    
    Currently there isn’t, but perhaps down the road.


13. What if I’m using Lightbox or a popup to display a video; can it still be indexed?
    
    Depends on the use case and how it’s rendered, but if indexing by search engines is important to you, it’s not the safest method. In the Webmaster Help Center, we explain that “When designing your site, it's important to configure your video pages without any overly complex JavaScript or Flash setup.” Most often, for bots, simpler is safer.

Have a safe and happy holiday!
