Passage Indexing
Passage indexing (or passage ranking) is an advanced Google algorithm update that allows the search engine to evaluate, index, and rank individual passages or sections of text within a webpage, rather than just evaluating the page as a whole. This means a highly specific, 200-word paragraph buried deep within a massive 5,000-word guide can rank independently for a long-tail query, even if the primary topic of the page is slightly different. Optimizing for passage indexing requires utilizing clear H2 and H3 header tags to structure content logically, ensuring each section provides a standalone, comprehensive answer to a specific question.
Passage Indexing Simplified
Passage indexing is a Google update that lets it find and rank a single, specific paragraph hidden deep inside a massive article. Even if the whole article isn’t about your exact search, Google can pull out the one paragraph that perfectly answers your question and show it at the top of the results.
