SEO On-Page: Video Optimization

Guides video optimization for Google Search (main results, video mode, Google Images, Discover), video sitemap, VideoObject schema, and indexing. Note: Google now prioritizes YouTube video results in search; YouTube + Reddit comprise ~78% of social media citations in AI Overviews. For YouTube-specific optimization, see youtube-seo; for GEO distribution via YouTube, see generative-engine-optimization. References: Google Video SEO, Semrush YouTube SEO.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope

• Discovery & indexing: HTML embed elements, video sitemap
• Metadata: Title, description, thumbnail; stable URLs
• Structured data: VideoObject schema
• Features: Video preview, key moments (Clip, SeekToAction), LIVE badge
• YouTube prioritization: Google favors YouTube in search; embed or host on YouTube for GEO citation

YouTube in Google Search (2025+)

Google prioritizes YouTube video results across search. YouTube receives 48.6B monthly visits (second to Google.com) and is treated as core search infrastructure for AI-driven discovery. Search Engine Land

Context	Implication
AI Overviews	YouTube citations surged 25.21% since Jan 2025; instructional (+35.6%), visual demos (+32.5%); long-form dominates (94%)
GEO	YouTube + Reddit = ~78% of social media citations; Perplexity (38.7%) and Google AI Overviews (36.6%) drive most YouTube citations
Strategy	Embed YouTube on site pages for dual indexing; or host on YouTube for GEO citation. See youtube-seo, generative-engine-optimization

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for brand and page context.

Identify:

1. Hosting: Self-hosted vs YouTube/Vimeo embed
2. Page type: Dedicated watch page vs supplementary (e.g. blog with embedded video)
3. Features needed: Preview, key moments, LIVE badge

1. Discovery & Indexing

Use Standard HTML Embed Elements

Google finds videos in <video>, <embed>, <iframe>, or <object>. Do not use fragment identifiers to load video; avoid requiring user interaction (click, swipe) to load.

Do	Don't
<video><source src="...mp4"/></video>	Fragment-only load; JS-injected without fallback
<iframe src="https://youtube.com/embed/...">	Hide video behind paywall without paywall structured data

JavaScript injection: If video is injected via JS, ensure it appears in rendered HTML; use URL Inspection in Search Console. If using Media Source API, inject HTML video container even when API fails so Google can find metadata.

Video Sitemap

Submit a video sitemap to help Google discover videos. Use <video:video> extension; <loc> = watch page URL.

Structure (from Google):

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
        xmlns:video="http://www.google.com/schemas/sitemap-video/1.1">
  <url>
    <loc>https://example.com/videos/watch-page.html</loc>
    <video:video>
      <video:thumbnail_loc>https://example.com/thumbs/123.jpg</video:thumbnail_loc>
      <video:title>Grilling steaks for summer</video:title>
      <video:description>Bob shows you how to grill steaks perfectly.</video:description>
      <video:player_loc>https://example.com/player?video=123</video:player_loc>
    </video:video>
  </url>
</urlset>

See xml-sitemap for sitemap index. Video sitemap is an extension; can be standalone or combined.

Indexing Requirements

• Watch page must be indexed and perform well in search
• Video embedded on watch page; not hidden behind elements
• Thumbnail: Valid, stable URL; ≥60×30 px; ≥80% alpha >250 (no heavy transparency)
• Supported formats: 3GP, 3G2, ASF, AVI, DivX, M2V, M3U, M3U8, M4V, MKV, MOV, MP4, MPEG, OGV, WebM, WMV, etc. Data URLs not supported.

Dedicated Watch Page

For video features (main results, video mode, key moments, LIVE badge), create a dedicated watch page per video—page whose primary purpose is to display that video. Examples: video landing page, episode player page, news video page. Not watch pages: blog with embedded video, product page with 360° video, category page with multiple videos.

---

2. Stable URLs

• Thumbnail: Stable URL; CDNs with fast-expiring URLs can prevent indexing
• Content URL: Stable for video preview and key moments; use contentUrl in VideoObject
• Player URL: Stable for embedUrl / player_loc

---

3. Thumbnail & Metadata

Thumbnail Sources (in priority order)

Source	How
<video> poster	poster attribute
Video sitemap	<video:thumbnail_loc>
VideoObject	thumbnailUrl
OGP	og:video:image

Use same thumbnail URL across all metadata sources.

Thumbnail Specs

Spec	Requirement
Formats	BMP, GIF, JPEG, PNG, WebP, SVG, AVIF
Size	Min 60×30 px; larger preferred
Transparency	≥80% of pixels with alpha >250
Access	Must be crawlable (no robots.txt block, no login)

Unique Metadata per Video

Provide unique thumbnailUrl, name, and description for each video in structured data and sitemap. Consistency with visible content is required.

4. VideoObject Schema

{
  "@context": "https://schema.org",
  "@type": "VideoObject",
  "name": "Grilling steaks for summer",
  "description": "Bob shows you how to grill steaks perfectly every time.",
  "thumbnailUrl": "https://example.com/thumbs/123.jpg",
  "uploadDate": "2025-01-15T08:00:00Z",
  "contentUrl": "https://example.com/video/123.mp4",
  "embedUrl": "https://example.com/player?video=123"
}

Required for rich results: thumbnailUrl, name, description. Add contentUrl for video preview and key moments. See schema-markup for full VideoObject; serp-features for Video SERP feature.

---

5. Video Features

Video Preview

Google selects short clips as dynamic previews. Allow Google to fetch video file; use max-video-preview robots meta to limit duration.

Key Moments (Chapters)

Method	Use
Clip	Exact start/end + label per segment; all languages
SeekToAction	Tell Google where timestamps live in URL; auto-detect; supported languages: en, es, pt, it, zh, fr, ja, de, tr, ko, nl, ru
YouTube	Timestamps in description; see youtube-seo

Disable key moments: nosnippet meta.

LIVE Badge

Use BroadcastEvent schema for live streams to show "LIVE" in results.

---

6. Allow Google to Fetch Video File

For video preview and key moments, Google must fetch the actual video bytes. Do not block contentUrl with noindex or robots.txt. Use stable URLs; ensure both watch page host and video/CDN host have sufficient capacity for crawling.

---

7. Third-Party Embeds (YouTube, Vimeo)

Google may index both your page and the platform's page. For your watch page: still add VideoObject and optionally video sitemap. For more features (preview, key moments), confirm the platform allows Google to fetch video files.

---

8. Removal & Restrictions

• Remove: 404 on watch page, or noindex; or set expires in schema / <video:expiration_date> in sitemap
• Geo-restrict: regionsAllowed or ineligibleRegion in VideoObject; <video:restriction> in sitemap

---

9. SafeSearch & Monitoring

• Mark pages appropriately for SafeSearch if content is adult. See Google SafeSearch.
• Search Console: Video indexing report; Video rich results report; Performance filtered by "Video" search appearance.
