What schema markup does
Schema markup is a shared vocabulary from schema.org that describes things on a page: a business with its address and hours, a question and its answer, an article with its author and date. JSON-LD is the format Google recommends, a small script block that sits in the page without changing what visitors see.
Structured data helps search engines understand a page with confidence, and it can make the page eligible for rich results such as business details, article information and other enhanced listings. AI assistants and answer engines also read it when they summarize businesses and pages, which makes it part of AI search visibility.
