Preview how your video appears in Google search with thumbnail, duration badge, and VideoObject schema. Optimize for video carousels.
This tool shows the search result your video page is able to produce: the thumbnail, the duration badge, the title, and the source line, plus the VideoObject structured data that feeds them. Paste the URL of the page that hosts the video and the preview renders the card Google could build from it, flagging schema properties that are missing or malformed. The usual surprise: the card is not assembled from your video file or your YouTube channel. It is assembled from schema.org markup in your page's HTML, so a page can rank for its text while its video never earns a carousel slot.
A concrete input and expected output from the current implementation.
Input
https://example.com/watch/how-to-sharpen-a-knife, a page whose VideoObject markup declares name "How to Sharpen a Knife", description, thumbnailUrl, uploadDate "2026-05-14", duration "PT4M12S", and contentUrl.
Expected output
A Google-style video result card: the thumbnail with a 4:12 badge in the lower corner, the title "How to Sharpen a Knife", a source line with the site name and the May 14, 2026 upload date, and a schema report listing name, description, thumbnailUrl, uploadDate, contentUrl, and duration as present and valid.
PT4M12S is ISO 8601 for 4 minutes and 12 seconds, rendered as the 4:12 badge in the format Google displays. Each element of the card exists only where the matching property exists in the markup, which is why a missing property appears as an empty slot in the preview.
The tool reads the VideoObject structured data declared on the page and maps each property to the piece of the Google result card it feeds: name to the title, description to the snippet, thumbnailUrl to the thumbnail, duration to the badge, uploadDate to the date line. A property that is absent or malformed leaves its slot empty, so a gap in the card pinpoints the property to fix.
schema.org requires the duration property in ISO 8601, for example PT4M12S for 4 minutes 12 seconds. The preview converts that value to the M:SS or H:MM:SS style Google shows and flags clock-style values like 4:12 or plain words, which Google cannot use. If duration is missing entirely, the card renders without a badge; the video can still appear in results.
No. The badge comes from the duration property, and its absence only means that property is missing or not written in ISO 8601 (PT4M12S, not 4:12). Google can still index the video and may show it with a thumbnail and title, just without the duration. Fix the property, re-run the preview, and the badge should fill in.
No. A complete card means the markup satisfies the schema requirements Google publishes, which is a prerequisite, not a promise. Whether the video earns a carousel slot depends on Google's indexing, on relevance for the specific query, and on eligibility rules outside the schema. Treat a full preview as ready to test in real search results, not as a ranking guarantee.
