People Also Ask Tools: Mine Google's Free Keyword Ideas (2026)

Here’s something odd about the phrase “people also ask tool.” Every single result on Google’s first page for it is a tool’s own landing page.

Not one honest review. Not one comparison. Just seven products each telling you they’re the best.

So we did the boring thing and actually tested them. And we found the same wall in every one: the feature you actually want, exploding a single question into a whole tree of related questions, is either paywalled, rate-limited, or capped at three searches a day.

Every ranking PAA tool caps its free tier or paywalls the export and recursive expansion that make the data worth having. The FlyByAPIs Google Search API returns the same questions as a clean JSON array on every request, with 100 free requests a month and no per-search cap. For anything past a single lookup, pulling the questions yourself is both cheaper and unlimited.

We run SERP scraping infrastructure for a living, so PAA data is something we pull thousands of times a day. This guide gives you both halves of the picture: which ready-made tools are worth your time, and how to skip the limits entirely and mine PAA questions yourself, for free, with about ten lines of Python or a single spreadsheet formula.

By the end you’ll know exactly which tool fits your workflow, and you’ll have a way to get unlimited question data that none of these seven products can match.

What “People Also Ask” really is (and why it’s a goldmine)

You’ve seen the box a thousand times. People Also Ask is the stack of related questions Google shows under the first result or two, each one expandable into a short answer pulled from a ranking page. It’s one of the most useful SERP features Google ever shipped, at least if you make content for a living.

Here’s the part most people miss. The box is recursive. Google shows four questions at first, but expand one and it loads a few more.

Expand those, and you get more again. One seed keyword can unfold into thirty or forty real questions people are typing right now.

Every question is a potential H2, an FAQ entry, or a whole article. String them together and you’ve got a content plan built entirely from demand you can verify.

The only real question is how you get them out of Google and onto your screen without doing it by hand. That’s where the tools come in, and it’s also where they start to disappoint.

The PAA tools worth your time, compared

We tested the seven tools ranking for this topic. Here’s how they stack up on the things that actually matter: how much you get free, whether you can export, and whether they do the recursive expansion that makes PAA data worth having.

Now the individual rundowns. I’ll be honest about where each one shines and where it stops.

1. AlsoAsked, the best pure PAA tool

If you only try one, make it AlsoAsked . It’s the one tool built specifically around the recursive nature of PAA, and it shows: you type a keyword and get a branching tree diagram of questions, sub-questions, and their sub-questions. It’s genuinely lovely to look at.

Best for: planning a single article where you want to see the question hierarchy at a glance. Just don’t expect to research a whole content calendar on the free tier.

2. AnswerThePublic, the famous one

AnswerThePublic is the tool everyone’s seen, mostly because of that spider-web visualization and Neil Patel’s marketing. It pulls questions, prepositions, and comparisons around a keyword, so it’s broader than pure PAA. With over a million users, it’s the default many marketers reach for.

Best for: a quick topic sweep when you want more than just PAA. If you specifically need Google’s People Also Ask questions, AlsoAsked is more precise.

3. Keywords People Use

Keywords People Use blends PAA questions with questions pulled from forums like Reddit and Quora. That mix is its edge, because it surfaces phrasing real humans use, not just what Google formats into a box.

4-7. The free single-lookup tools

Rankability , kwrds.ai , NeuralText , and PeopleAlsoAsk.ai all offer the same basic deal: a free box on their site where you type one keyword and get that keyword’s PAA questions back. No signup, no cost, no catch.

Best for: quick, single-keyword lookups. They’re the fastest way to grab PAA for one query, and they cost nothing. They just don’t scale.

The ceiling every one of these tools hits

Look back at that table and you’ll notice the pattern. It’s the same three walls, over and over.

Here’s the thing. PAA questions aren’t secret. They’re sitting right there on the results page for anyone to read.

The tools are really just charging you for the convenience of fetching and formatting them. Which means if you can fetch the SERP yourself, you can have all of it, with no cap and no export fee.

That’s not as hard as it sounds. Let me show you both ways.

Get unlimited People Also Ask data for free

The trick is to skip the middleman tools and pull PAA questions straight from the source: a live Google search, fetched through a SERP API. Our Google Search API returns the people_also_ask questions on every single request as a clean JSON array, and the free tier gives you 100 requests a month. That’s enough to pull PAA for around 100 keywords one at a time, or a handful of deep recursive trees.

One honest note before we start. The FlyByAPIs endpoint returns the PAA questions, exactly what you want for keyword and topic research, not the expanded answer paragraphs. For building content plans, briefs, and FAQ lists, the questions are the whole point.

There are two ways to use this, depending on how technical you feel today.

The no-code way: a Google Sheet formula

You don’t have to build a whole program. You paste a short snippet into your sheet once, and from then on it works like any other formula: =PAA("your keyword") and the questions drop into the cell.

Quick honesty note, because a lot of guides get this wrong. The plain IMPORTDATA function can’t do this, since it won’t send the API key header or read JSON. What you want is a tiny Apps Script custom function, which you set up once from Extensions, Apps Script:

function PAA(keyword) {
  const key = "YOUR_RAPIDAPI_KEY";
  const url = "https://google-serp-search-api.p.rapidapi.com/search?q=" +
    encodeURIComponent(keyword) + "&hl=en&gl=us";
  const res = UrlFetchApp.fetch(url, {
    headers: {
      "X-RapidAPI-Key": key,
      "X-RapidAPI-Host": "google-serp-search-api.p.rapidapi.com"
    }
  });
  const questions = JSON.parse(res.getContentText()).data.people_also_ask || [];
  return questions.join("\n");
}

Save it, go back to your sheet, put seed keywords down column A, and in column B write =PAA(A2). Drag it down. Now you have a living keyword sheet that pulls PAA questions for every row through the Google Search API for PAA data , with no daily cap and no copy-paste.

If a spreadsheet is as far as you want to go, stop here. You’ve already got something more flexible than any free tier above. But if you want the real prize, the recursive question tree, that needs a few lines of Python. See the SERP API endpoint docs for the full response shape.

The Python way: explode one keyword into a tree

This is the part AlsoAsked charges for, and you can build it yourself in an afternoon. The idea mirrors how the PAA box actually behaves: take a seed keyword, get its questions, then search each of those questions to get even more. Recursion.

import requests

API_KEY = "YOUR_RAPIDAPI_KEY"
HOST = "google-serp-search-api.p.rapidapi.com"
URL = f"https://{HOST}/search"
HEADERS = {"X-RapidAPI-Key": API_KEY, "X-RapidAPI-Host": HOST}

def get_paa(query):
    """Return the People Also Ask questions for one query."""
    params = {"q": query, "hl": "en", "gl": "us"}
    resp = requests.get(URL, headers=HEADERS, params=params)
    return resp.json()["data"].get("people_also_ask", [])

def explode(seed, depth=2, seen=None):
    """Recursively expand a seed keyword into a question tree."""
    if seen is None:
        seen = set()
    tree = {}
    for question in get_paa(seed):
        if question in seen:
            continue
        seen.add(question)
        # go one level deeper on each question
        tree[question] = explode(question, depth - 1, seen) if depth > 1 else {}
    return tree

questions = explode("keyword research", depth=2)
for q, children in questions.items():
    print(q)
    for child in children:
        print("   └─", child)

That’s the whole thing. A seed keyword goes in, and a nested tree of real Google questions comes out.

Set depth=2 and one keyword typically fans into twenty or thirty questions. Set it to 3 and you’ll have a content plan bigger than you can write in a month, all from demand Google confirmed is real.

Turning questions into an actual content plan

Raw questions are nice, but the point is what you do with them. Here’s how the marketers we talk to actually use PAA data once they’ve got it flowing.

That last one is worth dwelling on. Because the API takes a country code, you can mine what people ask in Germany, Brazil, or Japan, not just the US. Pair the PAA questions with our AI translation API and you’re planning localized content from local demand, which almost nobody bothers to do.

The same infrastructure reaches beyond search, too. If your research runs into products, our Amazon product data API pulls listings and reviews the same JSON-in-one-call way. For local business intent, the Google Maps data extraction API covers the “near me” questions PAA loves to surface.

And for company research, the Crunchbase company data API fills in the firmographics, while the jobs data API handles hiring-related queries. One key, the whole SERP and web data stack .

So which one should you use?

Depends entirely on how much you need and how often. If you go the self-serve route, here’s what each build gives you at a glance, before the use-case breakdown below.

Here’s the honest breakdown by use case.

The ready-made tools are great for what they are: fast, visual, zero setup. But the moment your PAA research goes past a handful of keywords, their pricing and caps stop making sense. At that point, pulling the questions yourself with the SERP API for PAA data is both cheaper and unlimited.

The honest bottom line

If you take one thing from this: PAA questions are free data that tools resell to you with a markup. For a single lookup, let them. For anything serious, extract People Also Ask questions via API yourself and skip the caps entirely.

Every tool on that first page is good at showing you one keyword’s questions. None of them lets you explode a topic into a hundred, export it, and drop it into your workflow without paying. Ten lines of Python and a free API key do exactly that.

So build the little recursive script and point it at your niche. Watch one keyword unfold into a month of content ideas, all sourced from what people are genuinely searching. That’s the whole game, and now it costs you nothing.

P.S. If you build the keyword-explosion script, run it once at depth 3 on your main topic and save the output. I keep one of those trees pinned for every site I work on. It’s the cheapest content strategy document you’ll ever make.

Oriol.
