VideoObject

A Clip is a Schema.org type used to designate a specific, named segment of a video or audio file. When used with VideoObject, it enables the Key Moments feature in Google Search, allowing users to jump directly to marked timestamps.

• Key Moments: Requires a defined start time and a text label for each Clip.
• Implementation: Nested within the hasPart property of a VideoObject.
• SEO Impact: Increases user engagement by surfacing deep links to specific sections directly in search results.

SeekToAction is an Action subtype that defines a deep link to a specific temporal point within a video. It is the mechanism that powers the interactive key moments interface in search results.

• Mechanism: Uses a target URL with a time-specifying fragment (e.g., #t=120) to instruct the player to seek to a precise second.
• Relationship: Typically embedded within a Clip definition to provide the actionable link for the marked segment.
• User Experience: Transforms a passive video result into an interactive, navigable content experience.

BroadcastEvent is a Schema.org type for describing a live or scheduled broadcast of a video stream. It connects a VideoObject to a specific temporal window, which is critical for live sports, concerts, and webinars.

• Live Badge: Triggers the red 'LIVE' badge in search results when the current time falls within the defined broadcast window.
• Key Properties: startDate, endDate, isLiveBroadcast, and workPerformed.
• Entity Linking: Connects the video to an Event entity, strengthening the knowledge graph around temporal content.

The transcript property of a VideoObject provides the full textual representation of the video's spoken content. This is a high-signal input for search engines to understand the semantic meaning of the video.

• Accessibility: Fulfills WCAG requirements for audio-visual media.
• Indexation: Allows search bots to crawl and rank the video based on its complete spoken content, not just the title and description.
• Format: Can be provided as plain text or linked as a separate WebPage resource.

Understanding the type hierarchy is essential for correct implementation. VideoObject inherits properties from its parent types, which must be considered for full validation.

• Thing: Inherits foundational properties like name, description, url, and sameAs.
• CreativeWork: Inherits author, datePublished, publisher, and thumbnailUrl.
• MediaObject: Inherits duration, contentUrl, embedUrl, and uploadDate.
• VideoObject: Adds specific properties like actor, director, transcript, and videoFrameSize.

InteractionStatistic is a type used to provide granular engagement metrics for a VideoObject, such as the number of views, likes, or comments. This provides explicit user-engagement signals to search engines.

• Watch Actions: Use WatchAction as the interactionType to specify view counts.
• Like/Dislike Actions: Use LikeAction or DislikeAction to provide sentiment signals.
• Accuracy: Values must be accurate and updated regularly to avoid structured data mismatch penalties.
