What Are People Also Ask Boxes? (PAA Explained)
You've seen them thousands of times. You search for something on Google, and below the top results — or sometimes above them — there's a box with four or five questions. Click one, and more appear. That's a People Also Ask box, and understanding what it is changes how you think about search.

What Are PAA Boxes?
People Also Ask (PAA) boxes are expandable question-and-answer panels that appear in Google search results. Each question is clickable: when you expand it, Google shows a brief answer pulled from a webpage, along with a link to the source.
They look like this:
- A grey box labeled "People also ask"
- Three to four questions listed vertically
- Each question has a small dropdown arrow on the right
- Clicking any question expands an accordion panel showing a short answer and a source link
Google introduced PAA boxes around 2015, and they've grown significantly since. According to data from Semrush's 2023 study of SERP features, PAA boxes appear in a large portion of Google searches, particularly for informational queries. They're now one of the most common non-ad features on the search results page.
The questions in a PAA box are algorithmically selected by Google. They're based on what other users commonly search for after (or alongside) your original query. Google uses its understanding of relationships between topics to surface questions it believes are related to what you're looking for.
Why Google Shows Them
PAA boxes serve Google's core mission: help users find what they need without forcing them to rephrase their search.
When you type a query, Google knows you might not have worded it perfectly. You might be looking for something adjacent to what you typed. PAA boxes surface those related angles proactively — they keep you engaged with Google's search experience rather than bouncing to another site or search engine.
From a business model perspective, PAA boxes are also effective at keeping users in the Google ecosystem. When you click a PAA question and then click the source link, you're still browsing within a Google-facilitated context.
The questions selected for PAA tend to reflect:
- Related concepts — questions that frequently appear together with your original query
- Definitional intent — "what is" questions that help clarify terms
- Procedural intent — "how to" questions that follow naturally from your topic
- Comparison intent — "vs" and "difference between" questions
The Cascade Effect
Here's the behavior that makes PAA boxes uniquely powerful for SEO: when you expand a question, Google loads more questions.
Click one PAA question, and two to four new questions appear at the bottom of the box. Click one of those, and more appear. A user can start with a search for "google analytics" and, through PAA clicks, find themselves exploring questions about bounce rate, session duration, GA4 migrations, and e-commerce tracking — all without typing a new search.
This cascade means that PAA questions are interconnected. Google maps relationships between topics and uses PAA to help users navigate that map.
For example, a search for "google search console" might show:
- What is Google Search Console?
- Is Google Search Console free?
- How do I use Google Search Console for SEO?
- What is the difference between Google Search Console and Google Analytics?
Expand question 4, and you might see:
- Does Google Search Console show traffic?
- What does Google Analytics track that Search Console doesn't?
- Can I use both GSC and GA4 together?
The cascade keeps branching. That's why PAA boxes generate a large share of Google's zero-click searches — users get enough information from the expanded answers that they don't always need to visit the source page.
PAA vs Featured Snippets
PAA boxes and featured snippets are often confused, but they're different features:
| Feature | Featured Snippet | PAA Box |
|---|---|---|
| Position | Position 0, above all results | Below top results (or sometimes above) |
| Format | One answer, usually a paragraph, list, or table | Multiple expandable questions |
| Trigger | Strong match to a specific query | Related questions to a broader topic |
| Content shown | Longer excerpt (40–60 words typically) | Shorter answers (2–4 sentences) |
| Source link | Shown prominently | Shown inside the expanded accordion |
| User interaction | No click required to see | Must click to expand each answer |
A page can appear in both a featured snippet and a PAA box for different queries. They're separate algorithms with separate ranking factors.
What PAA Means for Your SEO
PAA boxes have two direct effects on your organic search performance.
First, they appear in Google Search Console data. When your content appears in a PAA box and a user expands it, that generates an impression in GSC — even if they don't click through to your page. If they do click the source link, that's recorded as a click. This means GSC data for pages appearing in PAA boxes can show high impressions with lower-than-expected CTR, because many users get their answer directly from the expanded panel.
Second, PAA ranking is a separate opportunity from traditional ranking. A page that ranks in position 8 for a keyword might still appear in a PAA box above the fold, effectively getting top-of-page visibility for a related question. This makes PAA boxes a meaningful traffic channel for pages that don't rank #1.
To understand which of your pages are appearing in PAA boxes, look at queries in GSC where you have high impressions but a position between 3 and 10. Some of those impressions may come from PAA visibility rather than traditional organic positions.

Frequently Asked Questions
Do People Also Ask boxes appear for every search?
No. PAA boxes are more common for informational queries — "what is," "how to," "why does" — and less common for navigational queries (where someone is looking for a specific website) or transactional queries (where someone is ready to buy). They're especially prevalent for broad topic searches where Google knows users often have follow-up questions.
Can I see PAA impressions in Google Search Console?
Google Search Console doesn't break out PAA impressions separately from regular organic impressions. If your page appears in a PAA box and a user expands the answer, it counts as an impression in your GSC data. You can identify potential PAA visibility by looking at queries where you have high impressions but your average position is higher than expected (e.g., position 3–8 but many impressions).
Is ranking in a PAA box the same as a featured snippet?
No. Featured snippets and PAA boxes are separate SERP features with different ranking algorithms. A featured snippet appears at position 0 for a specific query match. PAA boxes appear for related questions and show shorter answers. Your content can appear in one, both, or neither — they're independent opportunities.
How does Google choose which pages appear in PAA boxes?
Google evaluates pages for PAA placement based on how well they answer the specific question in a concise, authoritative way. Pages that directly answer a question in their first paragraph or in a clearly formatted section tend to perform better. Structured content (short answer first, then elaboration) is more likely to be selected than pages that bury the answer deep in long paragraphs.
