Describe the page or content type
What Is Schema Markup?
Schema markup is structured data that describes the content of a webpage using a defined vocabulary such as Schema.org. It can help supported systems interpret entities and page details, including information about organizations, articles, products, services and events.
Structured data should accurately reflect information visible on the page. Do not add properties, reviews, prices, business details or other facts that cannot be substantiated by the actual content.
What Is JSON-LD?
JSON-LD is a way to express linked data using JSON. It is commonly added to a webpage in a script element with the type application/ld+json. Keeping the data separate from visible HTML can make it easier to maintain, but the markup still needs to be accurate and valid.
Choose a Schema Type That Fits the Page
Organization and WebSite
Organization markup can describe a real organization and its verified details. WebSite markup describes a website. Use only information that belongs to the site or organization being represented.
Article
Article markup can describe editorial content, including a headline, author and publication dates when those details are accurate and available on the page.
Product and Service
Product or Service markup should represent the actual offering. Include only applicable and verifiable attributes, and follow the relevant search engine requirements if you are aiming for a supported search feature.
LocalBusiness
LocalBusiness markup may describe a real local business and its accurate contact or location details. Never invent addresses, opening hours or other business information.
