Schema Markup

Also called: Structured Data, JSON-LD

Schema markup is usually added as JSON-LD. It can identify the business name, address, phone, services, people, products, and other facts already visible on the page in a consistent format.

Supported structured data can make a page eligible for certain search features, but Google still chooses whether to show a rich result. AI systems also choose their own citations. The markup gives machines an explicit version of facts that should already be clear to a person.

Visitors do not see the code directly. Search systems can use it alongside the page copy and other public sources, so the markup should stay accurate and match what the page actually says.

A plain example

LocalBusiness schema can identify a company’s official name, phone, address, hours, and service area. It labels those facts; it does not guarantee a particular search treatment.
