Schema.org

Schema.org is a shared vocabulary for structured data that describes content in a machine-readable way.

Schema.org provides a standardized vocabulary for describing entities such as articles, products, organizations, events, and other content in a machine-readable format. These definitions help search engines and other systems interpret the meaning and relationships of information more accurately. Schema.org markup is commonly implemented through JSON-LD and should reflect the actual content shown on the page. The concept is closely related to Structured Data and JSON-LD.

FAQ

Schema.org

Which Schema.org types make sense for company websites?
Organization, WebSite, BreadcrumbList, and Article for editorial content are usually enough, supplemented by Product or Service depending on the offering. Only types that describe content actually present make sense. Extensive markup unrelated to the page adds no value and only increases maintenance effort.
What mistakes commonly occur in Schema.org markup?
Common mistakes are values that are not visible on the page, outdated prices or ratings, and wrongly chosen types. Required properties are also often missing. The markup must mirror the visible content; deviations can lead search engines to ignore it. Validation tools help with checking.
Does Schema.org directly improve rankings?
No, a direct ranking effect is not established. Markup helps search engines understand content and can enable enhanced result displays when the provider's requirements are met. There are no guarantees. The value lies in clarity for machines, not in a ranking bonus.
What is the difference between Schema.org and JSON-LD?
Schema.org is the vocabulary, meaning the definition of types and properties such as Article or Organization. JSON-LD is a format for embedding that vocabulary in a page. Other formats such as Microdata are possible. The vocabulary determines what is marked up; the format determines how.
