How to validate a product idea with search data
·4 min read
Validate a product idea by checking the demand that already exists, then asking people to commit. Search data shows whether people look for a fix, whether companies pay to reach them, and who already sells to them. It cannot tell you whether anyone will pay you. For that, talk to 10 people and put up a waitlist or presale page.
Do the search checks first. They take an afternoon and cost far less than building the wrong thing.
Write the problem as searches
Start with the problem. Nobody searches for a product that does not exist yet.
Write 10 to 20 phrases a person with the problem would type. Mix three kinds:
- The problem itself, like "clients pay invoices late".
- The current fix, like "invoice reminder template".
- The category, like "invoice reminder software".
Add the names of the tools people use today. You will run all of these through the checks below.
Check search volume and trend
Volume shows how many people search each month. Trend shows whether that number is growing or shrinking.
Put your main phrase into Keyword Research. It returns related Google searches with monthly searches, difficulty, cost per click and trend, sorted into easy wins, blog topics and keywords worth bidding on. Pick your market if you sell in one country. Then paste your full list into Keyword Metrics to get the same numbers for every phrase.
What to look for:
- Several related phrases with steady searches. These are a better sign than one big generic term.
- A rising yearly trend. A falling trend can mean the problem is fading or moving somewhere else.
- A high cost per click. It means advertisers expect these searchers to buy.
All of these numbers are estimates. Use them for rough size and for comparing ideas with each other. Our keyword difficulty guide explains how to read the difficulty score.
See whether competitors pay to advertise
If businesses spend money on ads for a problem, buyers usually exist. Ads that keep running hint that the channel pays.
Enter the main players' sites in Competitor Google Ads to see how many Google ads each runs and how long each ad has been showing. Search your keyword in Meta Ad Finder to see the most recent active Facebook and Instagram ads that mention it, with start dates and landing pages.
Neither tool shows spend or results. An ad that has run for many months suggests it pays for itself, but that is a hint, and you should read it as one. No ads at all can mean a small market, or a channel nobody has tried yet.
Find what people ask AI about the problem
People describe their problems to ChatGPT in full sentences. Those questions show the words buyers use and the parts that confuse them.
AI Question Finder shows the questions people ask Google AI Overviews or ChatGPT about a topic, with the searches behind each, the start of the answer and the sources it lists. It covers one platform per run. If the answers point to a clumsy workaround, or to a tool people complain about, you may have found your opening.
Size up the existing players
Competitors are good news. They prove people pay to solve this problem.
Put each competitor into Domain Overview. It shows how many Google keywords the site ranks for, estimated visits, what those visits would cost in ads and how many sites link to it.
A few big players with huge numbers means you need a narrow niche to start. Many small players with modest traffic often means there is room for a better product.
Low search volume does not always mean no demand
Brand-new categories get few searches because people do not know the solution exists yet. They search for the problem or for workarounds instead.
If your category phrase shows almost no searches, check the problem phrases and the tools people use today. If those have volume, the demand is there under other words. If nothing shows up anywhere, search will not be your first channel. Read SEO for startups for what to do in that case.
Talk to 10 people and ask for a commitment
Search data tells you a market exists. It cannot tell you whether people want your version.
- Find 10 people who have the problem. Look in the communities, forums and review sites your searches led you to.
- Ask about the last time the problem happened, what they did and what it cost them. Do not pitch.
- Put up a one-page site that states the problem, your fix and a price.
- Ask for an email on a waitlist, or better, a paid presale or deposit.
- Count commitments. A friendly call means little. An email is a small signal. Money is the real one.
That page can become your launch page. Our guide to getting your first customers picks up from there. When you are ready to plan content, how to do keyword research covers the full process.
