Google Dataset Search is a specialized search engine that indexes dataset metadata published across the web using schema.org markup, covering government portals, academic repositories, and other data-hosting sites. It does not host data itself — it helps you find where a dataset lives.
It is a useful first stop when researching whether a public dataset already exists for a given topic before considering paid or custom collection options.
