When you publish a webpage, people are not the only ones reading it. Browsers, search engines, and sharing apps also look for clues about its meaning. This lesson explains how video structured data and video page semantics fits into that picture.
The Idea in Plain English
This example describes a real VideoObject using the Schema.org vocabulary. Structured data supplements visible HTML; it must not invent prices, authors, dates or reviews that the page does not actually provide.
You can test this using a small local HTML file. Change one part at a time and check the result in the browser before adding more code.
A Working Example
Read the sample once before copying it. Notice the element names and attribute values, then compare them with the explanation below.
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "VideoObject",
"name": "Make a Paper Plane",
"description": "A simple paper-plane lesson",
"thumbnailUrl": "https://example.com/thumb.jpg",
"uploadDate": "2026-10-12",
"contentUrl": "https://example.com/video.mp4"
}
</script>What Each Part Does
- The script element can load code or hold data; the type attribute tells the browser how to treat its contents.
- type chooses the relevant kind of script, input, media or embedded object.
The JSON-LD identifies one VideoObject object. Search services decide independently whether they can use that data or display a special result.
Try It Yourself
Replace the sample fields with accurate information from a real page; then validate the final JSON-LD.
Common Beginner Mistakes
- Publishing structured data that is invisible, misleading or inconsistent with the page.
- Copying the code without checking whether its linked files or endpoints exist; sample addresses and file paths need real resources.
- Choosing a tag only because its default appearance looks right, without checking whether it describes the content correctly.
Key Takeaways
- This example describes a real VideoObject using the Schema.org vocabulary. Structured data supplements visible HTML; it must not invent prices, authors, dates or reviews that the page does not actually provide.
- The JSON-LD identifies one VideoObject object. Search services decide independently whether they can use that data or display a special result.
- Test the markup in a browser, and check accessibility and real-world behavior where relevant.
