People Also Ask (PAA) answers the questions around your search. An AI Overview answers the search itself. That split still holds now that Google writes most PAA answers with AI, and it is the part worth understanding. This page sits under our guide to what People Also Ask is in Google, and compares PAA, AI Overviews and AI Mode side by side.
PAA, AI Overviews and AI Mode at a glance
| Feature | People Also Ask | AI Overview | AI Mode |
|---|---|---|---|
| What it is | A cluster of questions related to your search | An AI-generated snapshot that answers your search | A conversational AI search you can keep questioning |
| Where it shows | Inside the results, as a stack of questions | At the top of the results, on some searches | Its own mode, or one follow-up away from an AI Overview |
| What you see first | Questions. Answers stay closed until you click. | The answer | The answer, plus a box to ask more |
| Answer text | Once a quoted snippet from one page. Now mostly AI-generated. | Generated | Generated |
| How it goes deeper | Opening a question adds new questions | A follow-up moves you into AI Mode | More follow-up questions |
| On our three harvested result pages (27 Sep 2026) | On all three | On none | Not tested |
What People Also Ask is, officially
Google’s developer documentation calls PAA a “related questions group”: “a cluster of questions that are related to what the user initially searched for.” The same page, last updated on 4 February 2026, says that when a user expands a question, “they’re shown a featured snippet” (Google Search Central). Google’s help page on featured snippets says they “come from websites that Google finds,” picked “based on how well they answer your question and how helpful they are” (Google Search Help).
So the classic PAA answer was a quote. Google lifted a passage from one page and put that page’s link under it. Nobody at Google wrote it, and you could always see exactly where it came from.
The twist: most PAA answers are now AI Overviews
That description no longer matches what the box shows. AlsoAsked, a PAA research tool, has tracked how many PAA answers are AI-generated, and Search Engine Roundtable has reported the figures as they climbed:
- July 2025: 12.6% AI-generated. The rest were website-cited snippets (report).
- October 2025: 38%, up from 18% three months earlier (report).
- August 2026: 86%.
- First week of September 2026: 97% (report).
A second tracker, Allintitle’s Also Ask Miner, reported 100% AI-generated answers from August 2026. Treat both as second-hand: AlsoAsked’s Mark Williams-Cook and Allintitle’s Saeed Khosravi shared them on LinkedIn, and Search Engine Roundtable reported them. Both samples are English only (AlsoAsked’s covered 19.2 million queries made in 2026), and neither figure came from Google. According to Search Engine Roundtable, Google labels these answers as AI Overviews, the same label the summary at the top of the page carries. As the agency Relevant Audience put it, the answer text “is generated rather than quoted, and the generated text can draw on more than one page” (Relevant Audience).
Our own data agrees. On 27 September 2026 we opened the PAA box for three searches and saved all 149 answers. They read like small AI summaries, with headings and bullet points, and 145 of them cited more than one page. Two were labelled “AI Mode replied:” and carried no link at all. And none of the three result pages showed a separate AI Overview at the top, so the AI was all inside the box. Our favorite: Google’s PAA answer to “Are people also ask AI?” opened with “Yes, Google’s ‘People Also Ask’ (PAA) answers are now nearly 100% AI-generated,” citing Search Engine Watch. The box answered a question about itself, with AI. We dig into that one in is the People Also Ask section AI?
What AI Overviews are
AI Overviews are the generated summaries Google puts at the top of some results pages. Google’s help page describes “an AI-generated snapshot with key information and links to dig deeper” (Google Search Help). They rolled out to everyone in the U.S. on 14 May 2024, running on what Google called “a new Gemini model customized for Google Search” (Google). On 28 October 2024 Google announced expansion to more than 100 countries and territories and said AI Overviews would have more than 1 billion global users every month (Google). Since 27 January 2026, Gemini 3 has been their default model globally (Google).
For this comparison, what matters:
- They answer your query, not its neighbors. The summary is about what you typed. PAA is about what people ask around it.
- They don’t show on every search. Google’s documentation says AI Overviews appear only when its systems judge them “additive to classic Search, and as such, often don’t trigger” (Google Search Central). A Pew Research Center study of 68,879 Google searches from March 2025 found about 18% produced an AI summary. None of our three harvested result pages showed one on 27 September 2026, while all three had a full PAA box.
- You can’t switch them off. Google calls AI Overviews “a core Google Search feature” and says “features cannot be turned off.” The Web filter shows text links only.
Google is also frank that they get things wrong. Its help page says: “AI Overviews can and will make mistakes.” How often, and in which well-known cases, is covered in how accurate Google’s AI Overviews are.
Where AI Mode fits
AI Mode is the third piece, and the easiest to mix up with AI Overviews. Google introduced it on 5 March 2025 as a Search Labs experiment (Google) and rolled it out in the U.S., with no sign-up, on 20 May 2025 (Google). Google’s help page calls it “Google’s most powerful AI search experience” and says it “expands what AI Overviews can do with more advanced reasoning and ways of interacting” (Google Search Help). At I/O on 19 May 2026, Google said AI Mode had passed one billion monthly users and made Gemini 3.5 Flash its default model for everyone globally (Google).
The two share a method. Google’s Search Central documentation says both may use a “query fan-out” technique, issuing “multiple related searches across subtopics and data sources” to build a response. They are not the same system, though: “AI Mode and AI Overviews may use different models and techniques, so the set of responses and links they show will vary.” Whether that makes AI Mode more reliable is a question Google itself showed us, as a child of “people also ask vs ai overview.” We answer it in is AI Mode more accurate than AI Overview?
How they appear together on one page
On a search that triggers all three, the page stacks up like this:
- The AI Overview sits at the top, answering your query with links.
- PAA appears lower down (its position varies), showing a few related questions. Open one and you get its answer, now usually an AI Overview of its own, and Google adds new questions to the list.
- AI Mode is one step away. Since January 2026 you can ask a follow-up right from an AI Overview and carry on in AI Mode. Google calls it “one fluid experience,” and in May 2026 said the combined experience was live on desktop and mobile worldwide (Google).
So a single results page can now hold several AI answers: the one at the top, plus one inside every PAA question you open. The real difference is who chooses the question. You choose the Overview’s question by typing it. Google chooses PAA’s questions for you, based on what you searched, and every one you open brings more.
That last part is where PAA is still unique. In our harvest it took opening about 25 questions to reach 50 unique ones, starting from 4 visible on the page. An AI Overview never hands you 50 new questions. It hands you one answer.
What it means for publishers
PAA used to be a click you could win with one clear paragraph: your passage showed, and your link sat right under it. When the answer is generated from several pages, you become one of the sources instead of the source. Two data points frame what that costs, and they pull in different directions:
- Pew Research Center tracked 900 U.S. adults in March 2025. When an AI summary appeared, they clicked a traditional result in 8% of visits, against 15% when none appeared. They clicked a link inside the summary in 1% of visits (Pew).
- Google said in May 2024 that “the links included in AI Overviews get more clicks than if the page had appeared as a traditional web listing for that query” (Google).
Both can be true at once: fewer clicks overall, better odds for the pages that get cited. The part you control is being eligible and being worth citing. Google’s bar for AI features is short. A page must be indexed and eligible to show in Search with a snippet, and “there are no additional technical requirements” (Google Search Central).
You can finally measure it, too. On 3 June 2026 Google announced generative AI performance reports in Search Console, showing impressions in features such as AI Overviews and AI Mode by page, country, device and date. As of 31 August 2026 they are rolled out to all websites worldwide. The launch post lists impressions, not clicks (Google Search Central Blog).

What it means for researchers
If you use PAA to research a topic, change one habit: read PAA answers like AI output, not like quotes. A quoted snippet was only as good as the page it came from, and that page was one click away. A generated answer blends several pages and can state things none of them say. In an April 2026 study of top-of-page AI Overviews, the AI company Oumi found that only 67% of claims were supported by the sources cited (Oumi). Nobody has run that test on PAA answers yet, but they now carry the same AI Overview label.
Google’s own advice fits both: “Always check important info in more than one place.” Open the source, find the sentence, check the date. For more on judging what the box tells you, see how accurate People Also Ask information is.
The questions are a different story. They are not claims, so they can’t be wrong in the same way. They are a record of what Google connects to your topic, which is exactly what a researcher wants to map.
Why the PAA questions still matter for AI-era content
The answers inside PAA have changed hands. The questions are as useful as ever, maybe more.
Questions are where AI answers appear. Pew found that 60% of searches beginning with a question word produced an AI summary, against about 18% of searches overall. PAA is a ready-made list of question-shaped searches around your topic, so it shows you where AI answers are most likely to sit between you and the reader.
They sketch the sub-questions. Google says AI Overviews and AI Mode fan out into “multiple related searches across subtopics.” Google doesn’t publish those sub-searches, and PAA is not a window into them. But PAA does show which related questions Google links to a topic, and a page that answers them well covers more of the ground an AI answer might draw on.
They come as a tree. Open a question and Google adds children beneath it. That parent and child shape is a content plan: one page per question, linked to the page it grew from. Two of this page’s children came from real edges we recorded on 27 September 2026. Google showed “Is AI Mode more accurate than AI Overview?” under “people also ask vs ai overview,” then “How accurate are Google’s AI Overviews?” under that.
They need an edit. PAA drifts. For the search “people also ask,” only 6 of the 50 questions were about PAA itself, and the first off-topic one (“Can I tell who has googled my name?”) showed up at position 5. The reasons are in why People Also Ask drifts off topic. A raw question list needs a human pass before it becomes a plan.
That is the job PAA Box, our Chrome extension, was built for. It opens the box on the results page up to four levels deep (D0 Lid off to D3 All the way) and exports every question to CSV with its depth and parent question, so the tree survives into your spreadsheet. In answers mode it also saves Google’s answer and source for each question, which matters more now that you’ll want to check them.
