Passage Indexing

Passage indexing is a Google search technology that independently indexes and ranks specific passages within a page, rather than evaluating only the page as a whole. This allows long-form content to surface in search results for queries that match a particular section. Google identifies semantically distinct passages using natural language processing, then scores each passage independently against search queries. A page can rank for queries matching any of its passages, even if the overall page topic differs. For URL shortening services, passage indexing means that comprehensive resource pages about link management can rank for diverse long-tail queries. Deep-linking with URL fragments combined with short URLs can direct users to specific passages, improving content discoverability and user experience.
