Will People Actually Buy This? How to Check Before You Build

Before you build it — the signals that predict whether people will pay, pulled from what they already do.

This is about a product or service you haven't built yet, and whether the people you'd sell it to would actually buy. Not whether they'd say yes if you asked them directly — people are notoriously unreliable at predicting their own future purchases, and polite about it besides. The signals below come from behavior, not stated intent.

Ask about behavior, not hypotheticals

“Would you buy this?” is close to the least reliable question you can ask a prospective customer — it costs them nothing to say yes, and people generally want to be encouraging. “How do you currently handle this?” gets a real answer, because it's asking about something that already happened, not a hypothetical future.

Four real signals, in order of reliability

• What they currently pay for imperfect alternatives. If people already spend money on a worse version of what you're building, that's the strongest signal available — money has already changed hands for something adjacent to your idea.
• What advertisers spend to reach this audience. Sustained ad spend on a related search term is a real proxy, because businesses don't keep paying for clicks that don't convert into paying customers.
• Elaborate workarounds people already maintain. A spreadsheet held together with duct tape, a manual process repeated weekly — the more effort someone puts into a workaround, the more they'd likely pay to replace it with something that just works.
• Direct pre-commitment, where you can get it. A waitlist with a real email address, a deposit, a signed letter of intent — anything that costs the person something, even a small amount, is worth far more than a verbal yes.

Why search volume alone isn't a buying signal

People search for all kinds of reasons — curiosity, research, comparison shopping, and yes, sometimes an intent to buy. Search volume tells you people are engaged with the topic; it doesn't by itself tell you they're ready to pay. Pair it with a willingness-to-pay signal from the list above. For the search-volume side specifically, see our guide to checking whether anyone's actually looking.

What this doesn't replace

These are pre-launch signals — the strongest ones available before real transactions exist. The only fully reliable test is an actual offer, at an actual price, that people actually pay. Everything above is aimed at making that first real offer a much better-informed bet, not at replacing it.
