Validating a niche is an hour of work with numbers that protects months of effort and hundreds of thousands of rubles. Below is a 7-step checklist with stop criteria: if a niche stumbles at an early step, there is no point calculating further.
Step 1. Demand and its trend
Wordstat across the core keywords of the niche: total search volume, the 12-month trend, seasonality. Look broadly: not just the product name, but the queries about the problems it solves.
Stop criterion: a falling trend, or demand that rests on a single hype query.
Step 2. Revenue distribution at the top
Open the search results for the main keyword and look (with external analytics or by hand) at the top 30: how many cards share the bulk of the revenue, how many reviews the leaders have, how good their content is.
Stop criterion: 70–80% of revenue sits with 3–5 cards that have thousands of reviews and strong content — entry will cost as much as a small franchise.
Green flag: the top holds cards with weak photos and empty specifications — you can get past them on content: card SEO.
Step 3. The cost of entry through advertising
Assess the bids in the niche: the CPM in the ad dashboard for the niche keywords (on Ozon — Trafarety, the automated ad format; on Wildberries — the auction).
Stop criterion: the projected ad spend share (DRR) at entry is higher than your margin — this is a niche for sellers who already have organic traffic.
Step 4. Unit economics
The full per-unit calculation: purchase cost, commission, logistics (outbound plus the return leg for uncollected orders), storage, taxes, advertising, returns — the method.
Stop criterion: the margin only adds up without advertising and returns — which means it does not add up.
Step 5. Returns and the physics of the product
The category return rate (table), dimensions and weight (how they affect the tariff), fragility, shelf life.
Stop criterion for a newcomer: returns of 30%+ (try-on categories), breakage, perishables — these are categories for experienced sellers.
Step 6. Operational barriers
Certification, Chestny Znak (Honest Sign) labeling, brand rights, platform restrictions (prohibited goods).
Stop criterion: a barrier you are not ready to clear with money and time. A barrier you can clear and your competitors cannot is the opposite — it protects the niche.
Step 7. Test with a small batch
A niche that passes the six paper steps is then validated with money — a minimal purchase: how to test demand with a small batch. Only real sales confirm the calculation.

FAQ
"How do you validate a marketplace niche without analytics services?" The minimum: Wordstat for demand, a manual review of the top 30 results (reviews, prices, content), the ad dashboard for bids, and your own unit economics calculation. Services speed up step 2, but they do not replace the rest.
"What is the main sign of a bad niche?" Concentration: almost all the revenue sits with a handful of monopolist cards. Second in importance are unit economics that only add up under perfect conditions.
"How long does validating a niche take?" The first six steps take hours, not days. The small batch test takes a few weeks. That is an order of magnitude faster and cheaper than "validating" with a full purchase.
"Which matters more — demand or competition?" The ratio between them. High demand with an unbreakable top is worse than average demand with revenue spread thin and weak content among the leaders.
"Do you need to validate a niche if you already have the product?" Yes — the same steps, except the question is no longer "should I enter" but "how do I position it and how much do I spend to promote it". Running the numbers before launch saves you from promoting a product whose economics do not add up.
