Use when applies to any page embedding or hosting video content (YouTube, Vimeo, self-hosted). Use when adding video content to a site or auditing structured data coverage.
Use when reviewing templates, rendered HTML, or shared components related to Implement accessible breadcrumb navigation. Validate the final browser-facing markup, not just the source framework abstraction.
Use when auditing metadata, crawlability, structured data, or indexability related to Implement valid BreadcrumbList schema. Verify the rendered HTML and HTTP response rather than relying only on source files.
Use when reviewing templates, rendered HTML, or shared components related to Declare UTF-8 character encoding. Validate the final browser-facing markup, not just the source framework abstraction.
Use when reviewing templates, rendered HTML, or shared components related to Set text direction for RTL languages. Validate the final browser-facing markup, not just the source framework abstraction.
Use when auditing a site's meta tag uniqueness, generating page-specific meta descriptions, or reviewing CMS templates that inject the same description globally.
Use when you need to find the 2-3 most popular and well-maintained npm packages relevant to a frontend checklist rule, validate they meet quality thresholds, and add them to the rule's frontmatter.

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.
