TL;DR: A Google SERP feature showing an expandable list of related questions with short extracted answers and links to the source pages.
In a nutshell
PAA appears on roughly half of all Google searches, even more on informational queries. Click a question and Google pulls a 40 to 60 word answer from a ranking page, exposing your content as a cited source. Use question-form H2s with direct answers and FAQPage schema, so Google can extract you cleanly.
Quick answer: People Also Ask (PAA) is a SERP feature showing related questions in an expandable accordion. When you click a question, Google reveals a short answer extracted from a webpage and a link to that source. PAA appears in roughly 50% of all Google searches and is a major source of zero-click brand visibility plus a strong predictor of which content Google considers authoritative.
How PAA Works
Google generates PAA questions algorithmically based on related search queries. When a user expands a question, Google extracts a snippet (usually 40-60 words) from a page that ranks well for that question and shows it inline with a link to the source.
PAA is dynamic: clicking one question often loads more questions below it, creating a near-infinite scroll of related queries. This makes PAA both a discovery surface for users and an SEO opportunity for content creators. The shift towards extractive answer surfaces is part of the wider answer engine optimisation movement, and the official launch context for Google’s generative experience sits in the Google AI search announcement.
How to Get Cited in PAA
- Identify question keywords. Use Google’s autocomplete, AlsoAsked, or AnswerThePublic to find question variations users actually search.
- Use question-form headings. H2 or H3 in the format users would actually ask: "What is X?", "How do I Y?", "Why does Z happen?" This is the foundation of strong header tag structure.
- Provide a 40-60 word direct answer immediately below the heading. This is what Google extracts.
- Add FAQPage schema markup. Helps Google parse the question-and-answer pairs. Validate your markup using the Rich Results Test.
- Cover a topic comprehensively. PAA prefers sources that answer many related questions in one place, which compounds your wider topical authority.
Frequently Asked Questions
How often does PAA appear in search results?
Roughly 50% of all Google searches show PAA, with higher rates on informational queries (often 70-80%). PAA is one of the most common SERP features after Featured Snippets.
Does PAA hurt organic clicks?
Sometimes. When users find their answer inside a PAA box, they may not click through to the source. But PAA can also drive clicks to your site when the snippet shows you have the deeper answer. The net effect varies by query.
How is PAA different from Featured Snippets?
Featured Snippets are usually one box at the top of the SERP for direct queries. PAA is a list of expandable related questions, often appearing midway down the page. Both extract answers from web content, but PAA covers a broader topic.
Can I influence which questions appear in PAA?
Indirectly. Publishing well-structured answers to common questions in your niche increases the chance Google generates PAA boxes around your content. You can't directly control which questions appear, but you can influence which sources Google extracts answers from.
