See youtube seo , generative engine optimization Initial Assessment Project context: Read root contextus.md when present and load only the modules relevant to this task. Without Contextus, use available project material or user provided facts and ask for missing information; do not create a parallel context system. 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): 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 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](https://developers.google.com/search/docs/appearance/safesearch).
