People Also Ask (PAA) boxes are the expandable question-and-answer sections you see in Google search results - the ones that say "What is..." or "How do I..." and expand when you click them. In 2026, PAA boxes appear in approximately 85% of all Google search result pages (Semrush, Q1 2026), making them one of the most pervasive SERP features you can optimize for. Unlike featured snippets (one per query), a single query's PAA set can expand to 8 to 12 questions - each question is a separate traffic and citation opportunity.
To win PAA positions, your page needs two things: (1) it must rank in the top 20 organic results for the target query or a closely related query, and (2) it must contain a clearly structured question-and-answer block covering the PAA question, ideally marked up with FAQPage schema. The answer must be self-contained - 40 to 60 words - because Google extracts it as a standalone passage for PAA display. Context from surrounding text is not included.
The AEO connection is direct: Authoritas research shows pages winning 6 or more PAA questions within a topic cluster have a 62% chance of being cited in Google AI Overviews for related queries. PAA optimization is the most accessible entry point into AEO citation strategy because PAA positions are achievable from page 1 or 2 rankings, not just position-1 results. You don't need to be the best result - you need to have the best-structured answer for that specific question.
How PAA Boxes Work: An Interactive Walkthrough
People Also Ask boxes display dynamically generated questions related to the primary search query. Google generates PAA questions from its Search query graph - not just from your page's content. The box below simulates how PAA expansions work. Click any question to expand it, just as users do in actual SERPs.
People Also Ask
Answer Engine Optimization (AEO) is the practice of structuring web content so AI-powered answer engines - including Google AI Overviews, ChatGPT Search, and Perplexity - select it as the primary cited source for direct user queries.
PAA boxes expand to 8 to 12 questions when users interact - each expansion is another citation opportunity. Every subsequent question that appears in a PAA set generates a new AI-citeable content demand.
PAA Wins Predict AI Overview Inclusion: The Data
There is a measured correlation between PAA question ownership and AI Overview citation probability for the same topic. Pages that answer more PAA questions in the same topical cluster show substantially higher AI Overview inclusion rates. This is because both PAA answers and AI Overview sources draw from the same topical authority signal pool. Hover any bar to see the data point.

FAQPage Schema for PAA Optimization
FAQPage schema is the primary technical signal for PAA inclusion. It signals to Google that your page contains structured question-and-answer content that can be extracted for PAA and AI Overview citations.
Question phrasing
Write questions exactly as users type them into Google - use Google's own PAA box, 'People also search for' data, and AlsoAsked.com to source real user query language. Paraphrasing or 'improving' questions reduces exact-match PAA eligibility.
Answer length
The ideal FAQPage answer for PAA eligibility is 40 to 60 words - complete enough to standalone as a full answer, concise enough for Google to display in the PAA box without truncation. Answers over 120 words are rarely extracted into PAA boxes.
Answer self-containedness
Every FAQ answer must be a complete standalone response - do not use phrases like 'As mentioned above' or 'See the previous section.' Google extracts FAQ answers as isolated passages; context from surrounding content is not included in the PAA display.
Questions per page
Include 4 to 8 FAQ questions per page. Fewer than 4 reduces PAA footprint. More than 8 can trigger quality filters if the additional questions are lower-quality. Every question must be genuinely answerable by your specific content.
Question uniqueness
Each FAQ question on a page must be meaningfully different from the others. Pages with near-duplicate questions (e.g., 'What is AEO?' and 'AEO definition' targeting the same query intent) often have schema discounted for PAA eligibility by Google's quality filters.
