Passage Retrieval
Passage retrieval is the step where a search or AI system pulls specific paragraphs out of pages rather than judging pages as a whole. It is why a single self-contained paragraph can be quoted from an otherwise unrelated page, and why a paragraph that depends on the heading above it to make sense often is not used. The retrievable unit is the passage, not the document.
The practical consequence is a writing rule. A paragraph that opens with "This means you should..." cannot be quoted, because the reader of the quote never saw what "this" referred to. A paragraph that opens with "A subject removal deadline is the date by which..." can be quoted anywhere.
The same rule explains why question-shaped subheadings work well. A heading that asks the question a reader typed, followed by a paragraph answering it completely, produces a passage that matches a query and survives extraction.
This is the mechanism underneath most Answer Engine Optimization advice. Writing self-contained paragraphs is not a stylistic preference; it is what makes a passage eligible to be lifted.
Why it matters
Writing each paragraph so it survives being quoted on its own is the single highest-value habit for earning AI citations.
