Passage ranking
Definition: Passage ranking is a Google system that identifies individual sections of a web page to judge how relevant the page is to a search, so a strong answer buried in a long page can still be found.
Also called: passage indexing, passage-based ranking

What Google says
Google says passage ranking is an AI system it uses to identify individual sections of a web page to better understand how relevant the page is to a search (guide to Google’s ranking systems). Google announced it in October 2020 and described it at first as “passage indexing”, which caused confusion. Passages are not indexed as separate documents. The page is still the unit that ranks; the system simply looks at sections, not only the page as a whole, when judging relevance.
What it means in practice
Before passage ranking, a long page about home networking might struggle to rank for a narrow question like “why does my mesh Wi-Fi drop at night”, even if one paragraph answered it perfectly. Passage ranking lets that paragraph count. It mainly helps long, broad pages that cover many specific questions.
It does not reward length for its own sake. A page still needs to be relevant and useful as a whole.
How to apply it
- Give each section a heading that says what it answers, not a clever label.
- Lead each section with its main point, then add detail.
- Make sections self-contained: name the subject instead of relying on “this” or “it” from earlier.
- Split pages that try to answer unrelated questions.
Our view: the same habits help AI retrieval systems, which also select individual passages before generating an answer. That makes clear sectioning one of the few changes that helps classic rankings and AI citations at once. The answer engine optimization guide covers answer formatting in more detail.
