Which fields in the VideoObject Schema can improve the click-through rate of video searches?

When optimizing the VideoObject Schema to improve video search click-through rates, core fields include title (name), description (description), thumbnail URL (thumbnailUrl), upload date (uploadDate), and duration (duration). These fields enhance the attractiveness of search results by conveying key information to search engines. - name (Title): Should include core keywords, be concise and easy to understand, directly convey the video topic, and help users quickly judge content relevance. - description (Description): Supplement title information, naturally incorporate long-tail keywords, and outline the core value of the video (e.g., "Learn basic PS operations in 3 minutes") to improve search matchability. - thumbnailUrl (Thumbnail URL): High-quality, high-definition thumbnails can significantly attract user clicks; it is recommended to use images with clear themes and strong color contrast. - uploadDate (Upload Date): Displays content timeliness, which is particularly important for news and tutorial videos, allowing users to perceive content freshness. - duration (Duration): Clearly indicate the video length (e.g., "PT5M30S") to help users evaluate viewing time costs and reduce invalid clicks caused by unmet expectations. It is recommended to ensure these fields are accurate and complete, regularly update thumbnails and descriptions to maintain content attractiveness, and optimize keyword layout in conjunction with video content to further improve search visibility and click-through rates.
