Knowing what people are searching for is the raw material of any keyword research. This page is one layer down from our guide to question keywords. That guide covers the whole process. This one is about the raw material: the free places where Google shows you what people search, what each one is good for, and where each one stops. If you need a refresher on the box itself, see what People Also Ask is in Google.
First, which kind of “searching for” do you mean?
Google is not sure either. When we unpacked “how to find what people are searching for” with PAA Box on 28 October 2026 (google.com, depth 2), the box returned 27 questions. Only 4 were about finding what people search in general, such as “How do I find out what people are searching for on Google?”. Another 10 were about what is popular right now, like “What is the #1 trend right now?”. The largest group, 13 questions, was about privacy: “Can I tell who has googled my name?”, “Can others see my Google History?” and similar.
So there are really three questions hiding in one search:
- What are people searching for on my topic? That is demand research, and it is what this page is about.
- What is everyone searching for right now? That is trending searches, which Google Trends covers well.
- Who is searching for me? None of the tools on this page can show you who searched for a name. They show patterns across many searches, never individual searchers.
The split is a good example of why question research is worth doing. A keyword list would show “find what people are searching for” as one phrase. The questions show three audiences.
Google Autocomplete: how people start a search
Start typing in the Google search box and Google predicts the rest. Its help page on how autocomplete predictions work says that “autocomplete predictions reflect real searches that have been done on Google.” It lists the things that shape them: the language of the query, where it is coming from, trending interest in it, and your past searches.
Two more lines on that page matter for research. Autocomplete “doesn’t simply display the most common queries on a given topic,” and Google removes predictions that violate its policies, such as ones that are violent, sexually explicit, hateful, disparaging or dangerous. In a 2018 post on Google’s blog, Danny Sullivan explained that Google calls these “predictions” rather than “suggestions” on purpose: they are meant to help you finish the search you intended, not to suggest new ones. Our page on Google Autocomplete goes deeper into the feature itself.
How to use it
Type your topic slowly, add question words such as “how” or “why”, and research signed out so your own past searches don’t shape the list. The full method, including walking the alphabet, is on our Google Autocomplete page.
Where it stops
No numbers, and mostly short phrases rather than full questions. Autocomplete tells you how people begin. It does not tell you what they want to know once they have their first answer. For that, you need the next source.
People Also Ask: what people ask next
Search, scroll to the box labeled “People also ask”, and open a question. Google’s Visual Elements gallery describes it as “a cluster of questions that are related to what the user initially searched for.” Open one and Google usually adds more questions under it, so the box shows what people ask after their first question, not just how they start.
That is the part none of the other sources here can show you. The catch: no numbers, and the deeper you open it, the further it drifts from your topic. How to collect the questions, by hand or with a tool, and how to keep each one with its parent, is on where to find People Also Ask questions.
Related searches: what else people searched
Near the bottom of many results pages, Google lists related searches. Its documentation describes this as “a cluster of related searches that other people have done.” Clicking one runs a new search.
These are short phrases rather than questions, but they often fill gaps the PAA box leaves. When PAA drifts into trivia, related searches tend to stay closer to the original topic, and they are a quick way to find more seeds for your next PAA run.
Google Trends: when and where interest rises
Google Trends shows how interest in a search changes over time and across places. Google’s FAQ about Trends data explains how the numbers are made. Trends uses “only a sample of Google searches.” Each data point is divided by the total searches for its place and time range, and the results are “scaled on a range of 0 to 100 based on a topic’s proportion to all searches on all topics.”
So a score of 100 is the peak of interest within your chart, not a count of searches. That makes Trends good for comparing and timing, not for sizing.
How to use it
- Compare phrasings. Put two ways of saying the same thing side by side and see which one people use more.
- Check seasonality. Look at a few years to see whether interest peaks at the same time each year. Publish before the peak.
- Read the related searches panel. Trends’ help page on related searches describes top searches as terms “most frequently searched with the term you entered in the same search session,” and rising searches as those with “the most significant growth in volume in the requested time period.” When a rising term shows “Breakout”, the same page says it means “the search term grew by more than 5000%.”
- See what is popular right now. For the “what is everyone searching for today” question, Trends is the right tool, not PAA.
Where it stops
Relative scores from a sample. Google’s FAQ notes that low-volume terms can show as 0, so small, specific questions often have no usable Trends data at all.
Google Search Console: what you already show up for
If you have a website, Search Console’s Performance report shows how your site performs in Google Search: clicks, impressions, click-through rate and average position, broken down by the search queries people used. It is the only source on this page that is about your own site.
How to use it
- Filter queries for question words. Look for queries containing “how”, “what”, “why” or “can”. These are questions real people asked where Google already thought your site was worth showing.
- Look for impressions without clicks. A question you appear for but rarely get clicked on often means the page does not answer it clearly. That is a quick win.
- Use the top queries as seeds. Run them through PAA to see the questions around them.
Where it stops
It only covers searches your site already appears in. It can’t show you topics you haven’t covered yet, and you need a verified site to use it.
Sources outside Google
Google shows aggregate behavior. Your own business shows individual people. Both are worth reading.
- Your site search. If your site has a search box, what people type into it is a direct list of what they expected to find and maybe didn’t.
- Support emails and sales calls. The questions customers ask before they buy are often the same ones they type into Google first.
- Forums and communities. Places where people in your field ask each other questions show the wording and the worries behind a topic. Google often credits these sites in PAA answers, which tells you they are part of the conversation.
Use these to find seeds and to sanity-check what Google shows you. If customers keep asking something Google never shows, it may still deserve a page.
Putting the sources together
Each source covers a different stage of a search, so the order you use them in matters. This is the routine we use for one topic:
- Autocomplete for seeds. Ten minutes of typing gives you the common ways people start searching your topic. Pick the five to ten that read like real tasks or problems.
- People Also Ask for questions. Unpack each seed to D1 or D2. Export with parents.
- Related searches for gaps. Note any related search that suggests a branch the PAA box missed, and run it as a new seed.
- Clean and cluster. Remove duplicates and drift, then group what is left by meaning. Our page on keyword clustering covers how.
- Trends for timing and wording. Compare phrasings for your main clusters and check for seasons.
- Search Console for proof. See which of your clusters you already appear for. Start there.
The full single-topic version, with what to do at each step, is on how to use People Also Ask for keyword research.
What none of these tells you
Exact search volume. Autocomplete and PAA show no numbers at all. Trends shows relative interest. Search Console shows impressions, but only for searches your site already shows up in. If you want estimates of monthly searches, you need a dedicated tool, and even then treat the figure as an estimate. Our page on free keyword research tools compares the free options, including Google’s own Keyword Planner.
That is less of a problem than it sounds. For question research, the order of the work is: find the real questions first, in searchers’ own words, then decide which ones to answer. Demand data helps you rank the list. It can’t write it for you.
Common questions about the sources
Is autocomplete or People Also Ask better?
Neither. They do different jobs. Autocomplete is better for seeds and short phrasing; PAA is better for full questions and how they connect. We compare them in detail in Autocomplete vs People Also Ask.
Can I find the most searched questions on my topic for free?
You can get close. Questions that keep showing up across several seeds, in both autocomplete and PAA, are a strong sign of common interest. The method is on our page about the most asked questions on Google.
Do results differ by country?
Yes. Google says location shapes autocomplete predictions, and PAA reflects the Google you search on. PAA Box works on google.com out of the box, and you can allow other Google country domains when you need them, so you can research the market you actually serve.
