# 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](https://developers.google.com/search/docs/appearance/video), [Semrush YouTube SEO](https://www.semrush.com/blog/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](https://searchengineland.com/youtube-seo-ai-overviews-467253)

| 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](https://developers.google.com/search/docs/crawling-indexing/sitemaps/video-sitemaps) to help Google discover videos. Use `<video:video>` extension; `<loc>` = watch page URL.

**Structure** (from Google):

```xml
<?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://e
