Video SEO

Long definition

Google's video results are a separate index with separate ranking signals from web Search. A blog post with an embedded video can rank in regular Search for the article and in video Search for the same query — two impressions, two clicks, often from the same user. Most sites publish video and stop there. The optimization layer matters.

Hosting decision. Three patterns:

1. Self-host (HTML5 <video> or HLS). Maximum control over schema, sitemap, ads, and tracking. Forces you to handle storage, bandwidth, encoding, captions, and playback compatibility. Common for product demos and brand content.
2. YouTube embed. Cheap, fast, comes with discoverability inside YouTube's own search and recommendations (see youtube-seo). The embed doesn't pass video signals back to your domain — the YouTube URL ranks in Google Video Search, not your page.
3. Both. Host the canonical version on YouTube (for YouTube discoverability) and embed it on the page with VideoObject schema referencing both embedUrl and the YouTube contentUrl. The page can rank in web Search for the article context, the YouTube URL ranks in YouTube and Google Video Search.

Schema. VideoObject with name, description, thumbnailUrl, uploadDate, duration (ISO 8601 like PT2M30S), and one of contentUrl or embedUrl. See video-schema for the full field list and rich-result eligibility.

Video sitemap. A separate sitemap or extensions inside the regular sitemap that lists each page containing video, with the video's thumbnail, title, description, duration, and content URL. Often the easiest video-discovery win — see video-sitemap.

Transcripts. Visible text transcripts on the page give Google something to index beyond the schema fields. They turn 5-minute videos into 800-word indexable content. They also satisfy accessibility requirements and double as a CMS-friendly source for chapter generation.

Key moments. Google's key-moments feature pulls timestamped sections into the SERP, letting users jump to a specific point. Implement via schema's Clip or SeekToAction, or via YouTube chapters which Google parses automatically. Key moments dramatically expand SERP real estate for how-to and review videos.

Common misconceptions

• "Embedding YouTube counts as video on your page." For Google's video Search, the page can be eligible if it has VideoObject schema referencing the embed. But the YouTube watch URL competes for the same query — and often wins.
• "Video sitemap is optional." Without it, Google relies on schema and crawl discovery, which miss a lot of JavaScript-rendered video. The sitemap is the cheapest signal you can add.
• "Auto-generated YouTube captions are good enough." They're 80-90% accurate on clean speech. For specialist vocabulary (medical, legal, technical), they hallucinate enough to make the transcript misleading. Edit them.
• "Putting your videos on YouTube hurts your site's SEO." It doesn't hurt your site — YouTube and your site rank in different surfaces. The trade-off is reach (YouTube) vs control and traffic ownership (self-host).
