SEO On-Page: Video Optimization

SEO On-Page: 视频优化

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.

本指南涵盖针对Google Search（主搜索结果、视频模式、谷歌图片、Discover）的视频优化、video sitemap、VideoObject schema以及索引相关内容。注意：谷歌目前在搜索结果中优先展示YouTube视频结果；在AI Overview的社交媒体引用来源中，YouTube+Reddit占比约78%。如果需要针对YouTube的专属优化，请参考 youtube-seo；如果需要通过YouTube实现GEO分发，请参考 generative-engine-optimization。参考资料：Google Video SEO、Semrush YouTube SEO。

Initial Assessment

初始评估

Check for project context first: If

.claude/project-context.md

.cursor/project-context.md

exists, read it for brand and page context.

Identify:

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

优先确认项目上下文：如果存在

.claude/project-context.md

或

.cursor/project-context.md

，先读取文件获取品牌和页面上下文。

明确以下信息：

托管方式：自主托管 vs 嵌入YouTube/Vimeo视频
页面类型：专属播放页 vs 辅助展示页（比如嵌入视频的博客）
所需功能：预览、关键节点、直播标识

1. Discovery & Indexing

1. 发现与索引

Use Standard HTML Embed Elements

使用标准HTML嵌入元素

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.

谷歌可以通过

<video>

、

<embed>

、

<iframe>

或

<object>

标签识别视频。不要使用片段标识符加载视频；避免需要用户交互（点击、滑动）才能加载视频的设计。

推荐做法	不推荐做法
`<video><source src="...mp4"/></video>`	仅用片段加载；JS注入视频无降级方案
`<iframe src="https://youtube.com/embed/...">`	视频置于付费墙后但未添加付费墙结构化数据

JS注入场景：如果视频通过JS注入，要确保它在渲染后的HTML中存在；可使用Search Console的URL检查工具验证。如果使用Media Source API，即使API调用失败也要注入HTML视频容器，确保谷歌能识别元数据。

Video Sitemap

Submit a video sitemap 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://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.

提交video sitemap可以帮助谷歌发现视频。使用

<video:video>

扩展标签；

<loc>

对应视频播放页URL。

结构示例（来自谷歌官方文档）：

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://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>

站点地图索引相关内容参考 xml-sitemap。Video sitemap是扩展功能，可以单独提交也可以和普通站点地图合并。

Indexing Requirements

索引要求

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.

播放页必须被索引且搜索表现良好
视频嵌入在播放页中；没有被其他元素遮挡
缩略图：有效、稳定的URL；尺寸≥60×30 px；≥80%像素的alpha值>250（无大量透明区域）
支持格式：3GP、3G2、ASF、AVI、DivX、M2V、M3U、M3U8、M4V、MKV、MOV、MP4、MPEG、OGV、WebM、WMV等。不支持Data URL。

Dedicated Watch Page

专属播放页

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.

要获取视频相关特性（主搜索结果展示、视频模式入口、关键节点、直播标识），需要为每个视频创建专属播放页——页面的核心目的就是展示该视频。示例：视频落地页、剧集播放页、新闻视频页。不属于专属播放页的场景：嵌入视频的博客、带360°视频的产品页、展示多个视频的分类页。

2. Stable URLs

2. 稳定URL

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
```

缩略图：URL稳定；URL短时效的CDN会导致索引失败
内容URL：对视频预览和关键节点功能需要保持稳定；在VideoObject中使用
```
contentUrl
```
字段
播放器URL：对
```
embedUrl
```
/
```
player_loc
```
需要保持稳定

3. Thumbnail & Metadata

3. 缩略图与元数据

Thumbnail Sources (in priority order)

针对直播流使用

BroadcastEvent

schema即可在搜索结果中展示“LIVE”标识。

6. Allow Google to Fetch Video File

6. 允许谷歌抓取视频文件

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.

要实现视频预览和关键节点功能，谷歌必须能够抓取视频文件本身。不要用noindex或robots.txt拦截

contentUrl

。使用稳定URL；确保播放页主机和视频/CDN主机有足够的爬虫访问容量。

7. Third-Party Embeds (YouTube, Vimeo)

7. 第三方嵌入视频（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.

谷歌可能同时索引你的页面和平台的对应页面。针对你的播放页：仍需添加VideoObject，可选择提交video sitemap。要获取更多功能（预览、关键节点），需要确认平台允许谷歌抓取视频文件。
