People Also Ask: How PAA Works and How to Use It

People Also Ask (PAA) is the box of related questions Google shows alongside many search results. Each question expands into a short answer with a source, and opening one tends to load more questions beneath it. For SEO, PAA is two things at once: a SERP feature you can occasionally win, and the cheapest research tool you have for seeing which follow-up questions Google connects to a query.

This guide is for marketers and business owners who write their own content or brief writers. It covers how the box behaves in 2026, a repeatable way to turn PAA into a content plan, how to format answers so they can be lifted, and why PAA has become a working preview of the sub-questions AI answers are built from.

What is People Also Ask?

People Also Ask is Google’s related questions feature: a cluster of questions connected to what the person searched for. Google’s own visual elements gallery describes it as a “related questions group” and is blunt about control: you cannot decide what shows up there. There is no schema type, meta tag or setting that opts a page in.

How often it appears depends on the query mix you measure. Semrush reported PAA on 51.85% of searches in its Sensor data for August 2024. It is densest on informational and question-shaped queries, which is exactly where most content marketing lives.

The mechanics are simple from the searcher’s side:

1. Google shows a handful of questions, usually four.
2. Clicking one expands an answer with a source.
3. Google appends new questions under the list, often more specific than the one opened.

That third step is what makes PAA valuable for research. Each click reveals which questions Google considers the natural next step from the one you opened.

How the PAA box behaves in 2026

The biggest change is where the answers come from. Google’s documentation still says that when a user expands a question, they are shown a featured snippet, meaning a passage lifted from one page with a link. That was the norm for years.

In our live SERP check on 22 September 2026 (DataForSEO, Google US, desktop), we pulled the PAA boxes for ten informational queries in this post’s batch, from “semantic search” to “youtube seo”. All 60 expanded questions came back as AI-generated summary elements, not as single-page snippets. On those queries at least, PAA now behaves like a stack of small AI Overviews rather than a list of quoted pages.

Three practical consequences follow:

• Winning a PAA slot is less predictable. A generated answer can draw on several pages, so there is no single “position” to take.
• The questions matter more than the answers. The question list is still the clearest public signal of adjacent intent Google has.
• Your passage still needs to be liftable. Whether an extract or a summary cites you, the page that states the answer plainly and early is the easiest to use.

The diagram below shows the anatomy of a PAA box and the loop that makes it a research tool.

How to mine People Also Ask for a content plan

The fastest way to turn PAA into a plan is to collect questions two or three layers deep, group them by intent, and assign each group to exactly one page. Here is the method we use.

1. Start from your money topics, not from random keywords. List the five to ten subjects your service pages depend on. For a roofer that might be roof replacement, repair, insurance claims and materials.

2. Pull the questions. Search each topic in a clean browser and open questions to reveal the next layer. Tools do this faster: AlsoAsked says its standard deep search returns about 150 questions per query on average, and it lets you set a country or city, which matters because questions shift by location. A SERP API such as DataForSEO returns the same box as data.

3. Strip the noise. PAA wanders. Our “people also ask” check surfaced “What is the top 5 most googled questions?” and “Can I tell who has googled my name?”, neither of which belongs in a guide to SEO. Delete anything a customer would not ask you.

4. Group by intent. Put questions that one well-organized page could answer together. Questions that need a different page type (a comparison, a price page, a how-to) go in their own group. This is the same test described in our guide to search intent.

5. Map each group to one URL. Existing page if you have one, new page if you do not. Never split one group across two pages.

6. Decide the format of each answer. Definition, steps, list or table. See the next section.

The result is a table like this:

This planning step is where PAA earns its keep. Once questions are grouped, they plug straight into keyword research and a topic cluster built for AI citation.

The process below is the whole loop on one line.

How do you write answers PAA can use?

Write the answer as the first sentence under a heading that states the question, then support it. That structure serves PAA, featured snippets and AI summaries at the same time, because all three are looking for a passage that makes sense on its own.

Google says it uses a passage ranking system to identify individual sections of a page and judge how relevant the page is to a search. A heading plus a direct answer is the cleanest passage you can give it.

Practical rules:

• Put the question, or a close paraphrase, in an H2 or H3. Not every heading needs to be a question, but the ones that answer PAA questions should read like them.
• Answer in 40 to 60 words first. Then add the nuance, the exceptions and the example. The short version is what gets lifted; the long version is what earns the reader’s trust.
• Match the format to the question. “How to” wants numbered steps. “Types of” wants a list. “X vs Y” wants a table. Semrush notes PAA answers can appear as a paragraph, list, table, image or video.
• Make the passage self-contained. No “as mentioned above”, no pronouns pointing at a previous section. We explain why in content chunking for AI.
• Use FAQ sections for short, related questions that do not justify their own heading. Our guide to FAQ schema for AI answers covers when that markup is still worth adding.

If you do not want a passage lifted at all, Google documents the controls: nosnippet, max-snippet and the data-nosnippet attribute. Those are opt-outs only. There is no opt-in.

For the featured snippet side of this, including how to test which passage Google picks, see our featured snippets guide.

PAA as a proxy for AI fan-out questions

PAA is the closest thing Google publishes to the list of sub-questions its AI answers are assembled from. That makes it more useful now than when it was only a SERP feature.

When Google launched the current version of AI Mode in May 2025, it described the technique as query fan-out: “breaking down your question into subtopics and issuing a multitude of queries simultaneously on your behalf.” Deep Search, the same announcement says, “can issue hundreds of searches.” Those fan-out queries are not shown to you, and most have no measurable search volume, which is why keyword tools miss them.

PAA is different. It is Google showing, in public, the adjacent questions it associates with a query. The two lists will never match exactly, but they come from the same underlying idea: a question implies other questions. If PAA for “semantic search” includes “Does ChatGPT use semantic search?”, an AI answer to the head query will very likely need a sentence on that too.

We cover the mechanics of fan-out and how it decides who gets quoted in retrieval vs citation and Google AI Mode explained. The comparison below shows where the two overlap and where they do not.

What PAA cannot tell you

PAA shows you questions, not demand, and it is easy to over-read. Keep these limits in mind before you build a quarter’s content around it.

• No volumes. A PAA question may be searched ten times a month or ten thousand. Check the ones you plan to target as keywords.
• It drifts. The list changes with location, device and time. AlsoAsked makes a point of offering city-level data because intent varies by place.
• It wanders off-topic. Two or three layers down, questions often belong to a neighboring subject. Our check for “topical authority” slid into “Is domain.com a legit site?”
• It says nothing about quality. A question appearing in PAA does not mean the current answers are good, or that a better one would displace them.
• It is not a ranking factor. Answering PAA questions does not earn points by itself. It makes the page more complete for the searcher, which is the thing that matters.

Treat PAA as a question generator and intent map. Use search volume, your sales conversations and your own site search for prioritization.

Putting People Also Ask to work on your site

Start with one money topic. Pull its PAA questions three layers deep, cut the noise, group what remains by intent, and check each group against the pages you already have. Most sites find the same two problems: several questions with no page at all, and one page quietly trying to answer four intents at once.

Then rewrite the sections that should answer PAA questions so the answer comes first, in a heading that reads like the question. That single change helps with PAA, featured snippets, and the passages AI engines quote. If you want the writing side of this in more depth, our guide to SEO content writing walks through the brief-to-publish process.

If you would rather have the question research, page mapping and rewrites done as part of a wider plan for search and AI answers, that is the core of our AI SEO service.
