Alternate Markups for Videos

While Google recommends using video Sitemaps and schema.org to mark up your videos, we also support mRSS feeds, Facebook Share tags, and RDFa markup. If you are not already using one of these and are choosing which markup to use, we highly recommend video Sitemaps and schema.org.

mRSS

Google supports mRSS, an RSS module that supplements the element capabilities of RSS 2.0. mRSS feeds are very similar to video Sitemaps and can be tested, submitted, and updated just like Sitemaps.

Each mRSS feed must be under 50MB in size when uncompressed, and can contain no more than 50,000 video items. If your uncompressed file is larger than 50MB, or you have more than 50,000 videos, you can submit multiple mRSS feeds and a Sitemap index file. Sitemap indexes can contain mRSS feeds.

mRSS Example

Here's an example of an mRSS entry that provides all the key tags that Google uses. This includes <dcterms:type>live-video</dcterms:type>, which you can use to identify live, streaming videos.

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/" xmlns:dcterms="http://purl.org/dc/terms/">

mRSS Tags

Tag Required? Description
media:content Required

Encloses information about the video. This tag contains many key attributes.

The medium attribute specifies the type of content. This should be set to video.

The url attribute specifies the direct URL to the raw video content. If this is not specified, you must specify the <media:player> tag.

The duration attribute specifies the length of the video in seconds. This is an optional but recommended attribute.

For all of the other optional fields for the <media:content> tag, see the mRSS specification.

media:player Depends

You must specify at least one of <media:player> or the url attribute in <media:content>.

A URL pointing to a player for a specific video. Usually this is the information in the src element of an <embed> tag and should not be the same as the content of the <loc> tag.

media:title Required

The title of the video. Maximum 100 characters. All HTML entities should be escaped or wrapped in a CDATA block.

media:description Required

The description of the video. Maximum 2048 characters. All HTML entities should be escaped or wrapped in a CDATA block.

media:thumbnail Required A URL pointing to a preview thumbnail, which must be a GIF, PNG, or JPG image. The preview thumbnail must be hosted on the same domain as the video.
dcterms:valid Optional

The publication and expiration date of the video. Full specification of dcterms:valid.

Example:

<dcterms:valid>
  start=2002-10-13T09:00+01:00;
  end=2002-10-17T17:00+01:00;
  scheme=W3C-DTF
<dcterms:valid>
media:restriction Optional

A space-delimited list of countries where the video may or may not be played. Allowed values are country codes in ISO 3166 format. If there is no <media:restriction> tag, it is assumed that the video can be played in all territories.

The required attribute type should be set to country. Only country restrictions are supported.

The required attribute relationship specifies whether the video is restricted or permitted for the specified countries. Allowed values are allow or deny.

Learn more about using country restrictions.

media:price Optional

The price to download or view the video. Do not use this tag for free videos.

The required attribute currency specifies the currency in ISO 4217 format.

The required attribute type specifies the purchase option. Allowed values are rent, purchase, package, and subscription.

More than one <media:price> element can be listed (for example, in order to specify various currencies or purchasing options).

The full mRSS specification contains many more optional tags, best practices, and examples. Once you have an mRSS feed, you can test and submit it just like a video Sitemap.

Facebook Share

Facebook Share tags are added to the header of the page and can only describe one video. To make it easier for Google to index your video, the tags should describe the primary and most prominent video on the page.

Facebook Share Example

The following sample shows a video page header marked up in the Facebook Share format.

<head>
    <meta name="title" content="Baroo? - cute puppies" />
    <meta name="description" content="The cutest canine head tilts on the Internet!" />
    <link rel="image_src" href="http://example.com/thumbnail_preview.jpg" />
    <link rel="video_src" href="http://example.com/video_object.swf?id=12345"/>
    <meta name="video_height" content="296" />
    <meta name="video_width" content="512" />
    <meta name="video_type" content="application/x-shockwave-flash" />
</head>

RDFa Example

    <object width="512" height="296" rel="media:video" 
      resource="http://example.com/video_object.swf?id=12345"
      xmlns:media="http://search.yahoo.com/searchmonkey/media/"
