Pages with valid VideoObject schema are eligible for video-specific rich results and carousels in Google Search — a visibility advantage that pages without schema cannot access.
VideoObject JSON-LD schema to every page with embedded video contentname, description, thumbnailUrl, uploadDatecontentUrl (direct video file) or embedUrl (iframe embed URL)Find pages with embedded <video> elements, YouTube iframes, or Vimeo players. Check for a <script type='application/ld+json'> block containing "@type": "VideoObject". Verify required properties are present: name, description, thumbnailUrl, uploadDate. Run through Google's Rich Results Test.
Add a VideoObject JSON-LD block to each page with video. Populate name (video title), description (video description), thumbnailUrl (absolute URL to thumbnail image), uploadDate (ISO 8601 format), and either contentUrl or embedUrl. Validate with the Rich Results Test.
Explain how VideoObject schema enables video-specific rich results, which properties are required vs. recommended by Google, and the difference between contentUrl (direct file) and embedUrl (embed iframe URL).
Review metadata generation, rendered HTML, structured data, and response headers related to Add VideoObject schema to video pages. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +4 percentage points is the difference between those two pass rates over the 23 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
