What are question keywords and how do you find them?

Question keywords, sometimes called keyword questions, are the searches people type as questions. Most keyword research starts with phrases and a column of numbers. Question research starts with the exact things people ask Google when they want to know something, in their own words. That makes it one of the best starting points for planning content, because a question already tells you what the page has to answer.

This page is the wide view: what counts as a question keyword, why they are worth the effort, where to find them, what they can’t tell you, and how to turn them into pages. Each part has a page of its own underneath, linked as we go. If you want the single-topic method with People Also Ask, step by step, that lives on our page about people also ask keyword research.

What counts as a question keyword?

Any search that asks something. Most start with a question word:

• What, who, when, where: “what is a long tail keyword”, “when to plant tomatoes”.
• Why and how: “why is my cold brew bitter”, “how to descale a kettle”.
• Can, is, does, should: “can you reuse coffee grounds”, “is decaf bad for you”.
• Comparisons: “cold brew vs iced coffee” is a question without the question mark.

Some questions have no question word at all. Google’s Search Quality Rater Guidelines point out that [barack obama height] “has the same user intent as [how tall is barack obama], but is not in a question format.” So a question keyword is really about the need behind the search, not the punctuation. In practice, though, the searches with question words are the easiest to find and the easiest to read.

The examples above are ours, to show the shapes. They are not a list of measured searches.

Why question keywords are worth the effort

A question carries its intent

“Coffee scoop” could be a shopping search. “Is a coffee scoop 1 or 2 tablespoons?” is someone standing in a kitchen. The question tells you the job the page has to do, and roughly how much answer it needs. Reading that goal is a skill of its own, covered in what search intent is.

A question is already a heading

Pages built from questions are easy to outline. The main question goes in the title, the follow-ups become H2s, and the direct answer goes right under each one. Whether to use Google’s exact wording is a separate decision, covered in using People Also Ask questions as headings.

Questions live in the long tail

Most questions are specific, and specific searches each get few searches. That is the long tail, and it is huge: Ahrefs says keywords with fewer than 10 searches a month make up almost 93% of its US keyword database. Google said in 2019 that 15 percent of the searches it sees every day are ones it hasn’t seen before. More on that in what long tail keywords are.

People search in plain language

In the same 2019 post, Google’s Pandu Nayak wrote that people often use “keyword-ese,” typing strings of words they think Google will understand, and that Google’s language work helps most with “longer, more conversational queries.” The better search gets at plain language, the more searches arrive as real questions.

AI answers ask follow-up questions too

Google’s guide to its generative AI features describes query fan-out: “a set of concurrent, related queries generated by the model to request more information.” Its example is a search for “how to fix a lawn that’s full of weeds”, which might fan out to “best herbicides for lawns”, “remove weeds without chemicals” and “how to prevent weeds in lawn”. Those are the follow-up questions a good page would already answer.

Where do question keywords come from?

Google gives you several free windows onto what people ask. Each one shows a different slice and has a blind spot. Here is the map. The full tour, with how to use each one, is on how to find what people are searching for.

Autocomplete and People Also Ask are the two big ones, and they are easy to mix up. Autocomplete shows how people start a search. People Also Ask shows what they ask next. We put them side by side in Autocomplete vs People Also Ask, and the feature itself has its own page, google autocomplete.

Why People Also Ask is the best free source

Every other source on that list gives you a flat set of strings. People Also Ask gives you a tree. Google’s documentation calls it “a cluster of questions that are related to what the user initially searched for.” Open a question and Google usually adds more under it, so every question arrives with a parent: the question that made Google show it.

Read in order, those parent and child links show how Google expects a searcher to move through a topic. Here is a branch from a run we did on “how to make coffee” (14 October 2026, google.com, depth 2):

• How many scoops of coffee to make 2 cups of coffee?
  • Is a coffee scoop 1 or 2 tablespoons?
    • How many tablespoons of coffee do I need for 2 cups of coffee?
    • What is the proper size coffee scoop for making a cup of coffee?
    • How many scoops do you put in a 5 cup coffee maker?

A keyword list would show those as five separate rows. The tree shows they are one problem, measuring coffee, seen from five angles, and that they probably belong on one page.

Each question also opens to an answer with a credited source, which tells you who Google already leans on. Those answers are increasingly written by Google itself: Search Engine Roundtable reported AlsoAsked data showing that 97% of PAA answers in the first week of September 2026 were AI Overviews, up from 86% in August. Collecting the questions by hand or with a tool is covered in where to find People Also Ask questions.

What question keywords can’t tell you

How many people ask

Being in the box, or in Autocomplete, means Google connects a question to your search. It does not tell you how many people ask it. Autocomplete’s own help page says it “doesn’t simply display the most common queries on a given topic.” Treat every question as a candidate until you have checked demand somewhere else.

Whether it is on topic

The box drifts, and vague seeds drift fastest. When we checked Google’s US results for “question keywords” on 4 November 2026, People Also Ask showed four questions. Two were about keywords: “Which is an example of a keyword?” and “How to know which keywords are the best?”. The other two followed the word “question” somewhere else: “What are 10 good questions?” and “What is a question phrase?”. A specific seed, like a task or a problem, keeps the box on course. We explain the mechanics in why People Also Ask drifts off topic.

What it looked like yesterday

Results are a snapshot. Search Console’s help says search results “are specific to the time, place, device, and recent history of the person searching.” For anything important, run your research again on another day, and from the country you actually serve.

How to do question keyword research

The method below is the short version. Each step links to the page that covers it properly, and the full People Also Ask workflow is on people also ask keyword research.

1. Write specific seeds. Searches a real person would type, from several angles: the main task, problems, comparisons, costs. Autocomplete is a good place to find their wording, and Search Console queries you already get impressions for are strong seeds because you know they are real for your site.
2. Collect the questions. Unpack People Also Ask for each seed at the same depth, keep each question with its parent, and add anything useful from Autocomplete and related searches.
3. Cut the drift. Read every question once. Off topic goes. Use the parent to see where a branch left your topic and drop everything under that point.
4. Group by meaning. Merge rewordings of one need and split anything that mixes two needs. That step is keyword clustering, and intent is the test for it.
5. Check demand last. Take the shortlist, not the raw dump, to Google Keyword Planner, which Google says helps you “discover new keywords related to your business and view estimates of the searches they receive.” Use Trends to compare phrasings and Search Console to see which questions you already appear for.
6. Give each group one home. A big group with sub-questions is a page. A small one is a section. The method is in turning People Also Ask into a content plan.

Low or no measured demand is not a reason to drop a question on its own. Google Trends says that “search terms with low volume appear as ‘0’,” and most of the long tail looks like zero in most tools. If the question came up again and again in your research, it is probably worth answering.

Doing it across many searches

One search gives you a few dozen questions. A real site needs a few hundred, from many seeds. Three things keep a batch manageable:

• One depth for the whole batch, so results are comparable. Go deeper only on the seeds that deserve it.
• One sheet with the parent kept, plus a column for the search each question came from. A question that turns up under several seeds is one Google ties to more than one part of your topic. Getting the files into one sheet is on People Also Ask questions in Google Sheets.
• A gentle pace. Opening lots of questions quickly can look automated, and Google may show a captcha. Spread big batches out. Our page on bulk extracting People Also Ask questions covers the options, and why to avoid scraping scripts.

PAA Box, our Chrome extension, was built for this part: it unpacks the box on your own results page and exports each question with its depth, parent and search. PAA Box Pro can also be run by an AI assistant across a seed list, as described on the PAA Box MCP page. The judgment calls, what is on topic and what deserves a page, are still yours.

The most asked questions, and the right ones

A common shortcut is to look up lists of the most asked questions and build from those. Those lists are real, but they are about everything: “what time is it” and “what is my IP” sit at the top. What you need are the most asked questions on your topic, and those only show up when you research the topic itself. We cover both in what the most asked questions on Google are, including a way to find the leaders on your own topic by watching which questions repeat across searches.

Watch for searches that mean two things

Question research is good at catching searches with more than one meaning. Google’s rater guidelines use [mercury], which could mean the planet or the chemical element, and describe a dominant interpretation as “what most users mean when they type the query.”

The questions Google shows tell you which meaning it thinks is dominant, and who is asking. A keyword tool would lump the meanings together. The questions make the split obvious, and they tell you which audience a page is for before you write a word. If your page is for the less common meaning, say so in the first line. There is a worked example on how to find what people are searching for, where one search splits three ways.

Turning question keywords into pages

• One main question per page. It goes in the title, the H1 and the first sentence.
• Follow-ups become sections. The children of your main question are usually your H2s.
• Answer first. The first sentence under each heading answers it. Detail comes after.
• One home per question. If two of your pages answer the same question, they compete. Pick one and link to it from the other.
• No page per wording. Google’s spam policies define scaled content abuse as “when many pages are generated for the primary purpose of manipulating search rankings and not helping users.” Ten wordings of one question are one page.

Google’s helpful content guidance has a good final test: “Does your content leave readers feeling like they need to search again to get better information from other sources?” A page built around a cluster of real questions has a much better chance of passing it.

Common mistakes

• One seed, one run. A single search is a sample of a sample. Run several seeds, and repeat the important ones.
• Vague seeds. Two-word seeds drift fastest. Write seeds as tasks or problems.
• Dropping the parent. Without it you can’t see where a branch went off topic, and you can’t group by it.
• Treating presence as popularity. In the box means connected, not big. Check demand separately.
• Researching signed in. Google says your past searches shape Autocomplete. Research signed out or in a fresh profile when you want a cleaner view.
• Writing a page per question. Group first. Most questions are sections, not pages.
