Passage ranking is an AI system Google uses to identify individual sections of a page to better understand how relevant the page is to a search. Google confirms it in its ranking systems guide. It launched for US English queries in February 2021. Despite its early name, passage indexing, Google does not index passages separately; it still indexes and ranks pages. For sites, it means a specific answer deep in a long page can help that page rank, if the passage is clear.
What is passage ranking?
Passage ranking is a Google system that looks at individual sections of a page to judge how relevant the page is to a query. It lets a page rank for a narrow question answered in one paragraph, even when the page as a whole covers a broader topic.
Passage ranking is an AI system we use to identify individual sections or "passages" of a web page to better understand how relevant a page is to a search.

How does passage ranking work?
Google announced it at Search On in October 2020, describing it as a breakthrough in understanding the relevance of specific passages in addition to the page overall. Google said it would improve 7% of search queries across all languages once rolled out globally.
It is a ranking change, not an indexing change. After confusion over the original name, Google's Search Liaison account clarified in October 2020 that pages are still what is indexed.
This change doesn't mean we're indexing individual passages independently of pages. We're still indexing pages and considering info about entire pages for ranking. But now we can also consider passages from pages as an additional ranking factor

What evidence is there that Google uses passage ranking?
The evidence label is Confirmed. Google lists passage ranking in its ranking systems guide. Danny Sullivan confirmed in February 2021 that it had launched for US English queries, with other countries and languages to follow.
Google has not published which languages now have it, so the 7% figure from the October 2020 announcement should be read as Google's projection at the time, not a measured current figure.

What are the common myths about passage ranking?
Most misreadings come from the original "passage indexing" label.
- Myth: Google indexes passages separately. Google said it does not; it still indexes pages.
- Myth: passage ranking is a featured snippet feature. Google's Search On post says the improvement applies to how web pages are ranked overall.
- Myth: long pages now beat short ones. Passage ranking helps a relevant passage be recognised; it does not reward length. See padded content.
- Myth: there is a passage specific optimisation. Google's Search Liaison said there is nothing special creators need to do.
What should sites do about passage ranking?
Google says there is nothing special to do. The testable implication is still useful: on long pages that cover several subtopics, each specific answer should be recognisable as a passage. That means a heading that names the question and a first sentence that answers it.
Look for long pages that earn impressions for specific long tail questions but sit on page two or three for them, then check whether the answer is buried inside an unheaded block. Adding a clear heading and a direct first sentence is a small, reversible test.
Which Laurelin audit checks test for passage ranking?
These checks test whether passages are clear enough to be recognised. They are proxies; Google's passage scores are not visible.
Specific answers buried in unheaded blocks of long pages: the new check for this page.
Passages not self-contained: a passage that relies on earlier context is weaker on its own.
Answer buried, lead doesn't answer: the same problem at page level.
Question heading with no direct answer: a heading promises a passage the text must deliver.
Incoherent heading outline: headings are the clearest passage boundaries a page offers.

Frequently asked questions about passage ranking
Is passage ranking the same as passage indexing?
It is the same system under a corrected name. Google said it does not index passages separately; it indexes pages and can use passages as an additional ranking factor.
When did passage ranking launch?
Google confirmed it launched for US English queries on 10 February 2021, with more countries and languages to follow.
Do I need to change my content for passage ranking?
Google says no special work is needed. Clear headings and direct first sentences make individual answers easier to recognise, which is good practice anyway.
