Schema.org

Schema.org is a shared vocabulary that people use to add structured information to web pages so machines can understand the meaning behind the content. Instead of just showing text on a page, you can mark up things like events, products, recipes, reviews, and people in a consistent way that computers recognize. This markup can be embedded using common formats so search engines, assistants, and other tools can read it easily. Because it uses agreed-upon definitions, different websites can describe similar things in the same language, which helps automated systems combine and compare information reliably. This matters because when machines understand your content, they can do more with it: produce rich previews, answer questions, populate knowledge panels, or surface specific attributes like price or availability. Using these structured descriptions improves the chances that your content will be used in summaries or featured results, and it also reduces ambiguity about what your content actually describes. It doesn’t replace good writing, but it makes your pages more discoverable and useful to people who interact with search interfaces or automated assistants. The vocabulary is maintained and extended by many contributors, so it keeps evolving to cover new kinds of content and uses.
