A Video Sitemap is a specialized XML file or a set of <video:video> tags embedded within a standard XML Sitemap, designed to expose video-specific metadata to crawlers. It explicitly declares the location of a video's thumbnail, its raw file URL or player location, duration, and family-friendliness status, ensuring search engines can discover and understand video content that might otherwise be opaque to traditional HTML parsing.
Glossary
Video Sitemap
An extension of the XML sitemap protocol that provides metadata about video content on a page, including duration, thumbnail location, and family-friendliness status.
CRAWLER DIRECTIVE
What is a Video Sitemap?
A Video Sitemap is an extension of the XML Sitemap protocol that provides search engines with structured metadata about video content embedded on a webpage, enabling richer indexing and enhanced presentation in search results.
By implementing a Video Sitemap, developers provide precise signals for video indexing, including expiration dates, live-stream status, and geographic restrictions. This structured data feed is critical for programmatic content infrastructure, allowing massive video libraries to be efficiently crawled without relying on bots to execute complex JavaScript players or guess the og:video tags, directly improving rich snippet eligibility in search results.
PROTOCOL EXTENSIONS
Key Features of Video Sitemaps
Video sitemaps extend the standard XML sitemap protocol with a dedicated namespace to provide search engines with rich metadata about video content embedded on a page, enabling enhanced rich results and indexing.
01
Core Video Metadata Tags
The video sitemap protocol introduces a suite of required and optional tags within the <video:video> element. Required tags include <video:thumbnail_loc> (a URL pointing to a representative image), <video:title>, and <video:description>. Optional but critical tags include <video:content_loc> (the actual video file URL) or <video:player_loc> (an embeddable player URL). Providing the raw file location via content_loc is preferred for direct indexing.
02
Thumbnail Specification
The <video:thumbnail_loc> tag is mandatory and must point to a static image file representing the video. Search engines use this thumbnail in rich results. The URL must be crawlable and not blocked by robots.txt. Supported formats typically include .jpg, .png, and .gif. The image should be at least 160x90 pixels to meet minimum resolution requirements for display in search results.
03
Duration and Family-Friendliness
Two critical optional tags provide context for indexing. <video:duration> specifies the runtime in seconds (e.g., 305 for a 5-minute video). <video:family_friendly> accepts a boolean yes or no value. Marking content as no prevents it from appearing in filtered search results. Accurate duration data helps search engines cluster content by format (short-form vs. long-form).
04
Platform and Restriction Attributes
The <video:platform> tag allows specification of the hosting platform (e.g., web, mobile, tv). The <video:restriction> tag enables geo-fencing by defining countries where the video can or cannot be played, using ISO 3166 country codes and a relationship attribute set to allow or deny. This prevents serving restricted content to users in blocked regions.
05
Live Streaming Broadcast Metadata
For live content, the <video:live> tag signals that the video is a broadcast rather than on-demand. This tag accepts a boolean value. When set to yes, search engines may display a 'LIVE' badge in rich results. This tag should be removed or updated to no once the broadcast concludes to prevent stale live indicators.
06
Namespace Declaration and Validation
To be valid, the sitemap must declare the video namespace in the root <urlset> element: xmlns:video="http://www.google.com/schemas/sitemap-video/1.1". Each <url> entry can contain one <video:video> block, which itself can describe multiple videos on that page. Validation against the official XSD schema ensures parsers can process the file without errors.

Frequently Asked Questions
Clear answers to the most common technical questions about implementing, validating, and optimizing video sitemaps for search engine discovery.
A video sitemap is an extension of the XML sitemap protocol that provides search engines with structured metadata about video content embedded on a webpage. It works by wrapping video-specific tags—such as <video:title>, <video:description>, <video:thumbnail_loc>, and <video:content_loc>—within a standard <url> entry. This explicit declaration helps crawlers discover and index video content that might otherwise be invisible to them, especially when videos are loaded via JavaScript or hosted on a third-party platform. The sitemap communicates critical attributes including duration, upload date, family-friendliness status, and whether a subscription is required, enabling rich video snippets in search results.
