Schema Markup Meaning in Plain English
Websites commonly provide schema vocabulary using JSON-LD. It can identify things such as an organization, article, service, breadcrumb trail, or software application.
Structured data can make content easier for search systems to interpret, but it does not guarantee a special search feature or ranking improvement.
Example
An Article object can identify the headline, publication date, author, image, and page it describes—provided those facts are accurate and supported by the page.
Why It Matters
Correct structured data reduces ambiguity and can make pages eligible for relevant search presentation features.
