You can’t know for certain. But you can find evidence in about ten minutes, using Etsy’s own free search.
Look at listings already selling something like what you’re considering, and check three things: a Bestseller badge, a high review count, and—the part almost everyone skips—reviews from the last few weeks.
Recent reviews are the difference between demand that exists and demand that existed. If a product type has all three signals, people are buying it right now. If it only has the first two, you may be about to spend your evenings building for a market that has already moved on.
Why “it looks like it’s selling” usually isn’t enough
The common advice is to search your idea on Etsy and see whether anything similar is doing well. That’s the right instinct, and it stops one step too early.
A listing can look extremely successful and be finished. Etsy review counts accumulate forever — a shop that sold hard for two years and stopped last spring still shows every review it ever earned. Nothing on the page says “this was popular in 2024.” You have to go and look.
This matters more for people selling around a job than for anyone else. If you have five free hours a week, one abandoned product costs you a month. The check that prevents it takes two minutes.
What counts as proof that a product sells?
Three signals, in order of how much they tell you.
The Bestseller badge. Etsy applies it to listings with strong recent sales and good reviews in their category. It’s the most direct signal Etsy gives you, and unlike a review count, it reflects recent performance. Also look for “Popular now.”
Review count. More reviews means more completed purchases and a shop buyers trust enough to buy from. One caution most guides get wrong: the number you see under a listing in search results is usually the shop’s rating, not that item’s. Open the listing and scroll to the reviews section to see how many belong to the product itself.
Review dates. The one that actually decides it. See below.
What is not proof: the number of listings competing for a keyword, how good a product looks, favorites, or your own certainty that something is a great idea. Favorites in particular mislead — people save things they never buy.
How do I know the demand is still active?
Open the listing, scroll to the reviews, and read the dates rather than the text.
- Reviews in the last few days or weeks — the demand is live. Continue.
- Newest review is several months old — treat it as a warning. Something that once sold well may have stopped, and the review count won’t tell you that.
- Reviews clustered around one season last year — that’s a seasonal product. It may be a fine thing to make, but make it on the right timeline.
This is the step that separates research from guessing, and it’s the one most sellers skip because the review count already looked convincing.
Do this on two or three listings, not one. A single shop can go quiet for reasons that have nothing to do with the market — a seller went on holiday, changed direction, or got sick. A whole page of stale listings is a market telling you something.
Where do I check this without paying for a tool?
Everything above runs on Etsy’s own search, free. Two more free sources are worth knowing:
Etsy’s search bar autocomplete. Start typing your product type and read the suggestions. Those come from what buyers are actually typing, ranked roughly by how often. It’s the cheapest keyword research that exists, and it’s built into the site.
Marketplace Insights, in Shop Manager → Stats → Marketplace Insights. Etsy shows you search volume and related terms from its own data. It’s free with a shop, and most sellers have never opened it.
Paid tools — eRank, EverBee, Alura — add depth if you already pay for one. None of them is required to answer the question in this article, and none of them will tell you whether a product’s demand is current any better than the review dates will.
How many reviews is enough?
There’s no universal number, and anyone giving you one without asking about your category is guessing.
What works is relative. Search your product type, look at the first page, and ask whether the successful listings are in the hundreds or the tens of thousands. That’s your category’s scale. Then judge any single listing against it.
As a working floor in most digital categories, 500 or more reviews is enough to say people are buying this type of thing. Five thousand and up means established, competitive demand — good proof, harder to break into.
But the threshold matters less than the recency. A listing with 600 reviews and one from yesterday is better evidence than one with 9,000 whose newest is from March.
What if my idea is different from everything already selling?
Then you have two possibilities and no way to tell them apart from the outside: you’ve found a gap, or you’ve found a space people already tried and left.
The honest answer is that a genuinely new idea can’t be validated this way. Nothing exists to check. You’re making a bet, and the way to make that bet cheaply is to make it small — the simplest possible version, listed quickly, rather than the complete version after a month of work.
For most sellers most of the time, though, “nothing like this exists” turns out to mean “nothing like this exists in the first ten results I looked at.” Search two or three different phrasings before you conclude you’re alone.
How do I test an idea without spending a hundred hours on it?
Make the smallest complete version.
The trap isn’t picking the wrong idea — it’s picking an idea and then building the full version of it before finding out. A planner becomes a weekly planner. A bundle becomes one template. A large guide becomes one focused tool. If it sells, expand it. If it doesn’t, you spent an evening.
This is also why finishing beats optimizing. An unfinished product tells you nothing at all. A rough one that’s live tells you whether anyone wants it.
What this method can’t tell you
It tells you whether a type of product has buyers. It does not tell you whether your version will sell.
Execution still decides that: your photos, your title, your price, whether your shop looks like somewhere a stranger will hand over money. Proof of demand only means you’re building for a market that exists — which puts you ahead of most sellers, and is not the same as a guarantee.
It also can’t tell you how competitive a niche is to enter. Strong demand and thousands of established listings can be a worse bet than modest demand with room to be seen.
Frequently asked questions
How do I know what will sell on Etsy?
Look for proof rather than opinion: a Bestseller badge, a healthy review count, and recent review dates. All three together mean people are buying that type of product now. Etsy’s own free search shows you all three.
Can you make $10,000 a month on Etsy?
Some shops do. Most don’t, and the ones that do usually have hundreds of listings, years of history, or a product with unusually high margins. A more useful target for someone selling around a job is steady, repeatable sales — the first $1,000 month is a much better milestone to design for than a number you read in a headline.
How much does Etsy take from a $1000 sale?
On $1,000 in sales, Etsy charges a 6.5% transaction fee ($65) plus 3% payment processing + $0.25 per order (roughly $30, plus a quarter for every order). Listings cost $0.20 each to publish. So expect around $95–110 in fees before advertising, and note that payment processing rates vary by country.
Why are so many sellers leaving Etsy?
Common reasons given are rising fees, increased competition from mass-produced and drop-shipped listings, and unpredictable search visibility. Whether leaving is the right response depends on where your sales actually come from — a shop that only ever got traffic from Etsy search has a different problem from one with its own audience.
Does the number of competing listings tell me anything?
Only in combination with everything else. A high listing count means competition, not demand, and a low one can mean either an untapped gap or no buyers. Sales signals tell you about demand; listing counts tell you how hard it will be to be seen.
Where to go from here
Checking whether something sells is ten minutes’ work. The harder part is what comes next: choosing one idea, cutting it down to something you can finish, and getting it published before the week disappears.
That’s what the Seller Guide to Building a Bestseller in One Day does — seven steps from a proven idea to a live listing in a single day, with the research above as steps two and three. It’s $2, and it comes with a guarantee that you’ll finish.
If you’d rather start by finding out what’s actually holding your shop back, the free bottleneck diagnostic takes five minutes and tells you whether traffic, offer, platform, or market is your real problem.
