Validation is the process of collecting evidence that a defined buyer will purchase a specific offer at a workable price. Likes and trend charts are weak signals; a qualified inquiry, pre-order where lawful, or real purchase is stronger. Test the product itself, the supplier and the economics before committing to a broad catalog.

Build an evidence ladder
At the bottom are your own enthusiasm and a viral video. Higher up are repeated buyer complaints, search demand and competitor purchases. Stronger still are people who describe the problem in their own words, ask about delivery at your price, or place a legitimate order. Shopify's product-market-fit guide points to low-risk tests and real customer behavior rather than a single attractive trend.
Ask questions that can disconfirm the idea
Interview prospective buyers about their last attempt to solve the problem, what it cost, and what disappointed them. Avoid “Would you buy this?”—people often answer politely. Show a plain offer with an honest price and delivery estimate. Note objections verbatim. If everyone wants a different feature, the target buyer may be too broad.
Test supply at the same time
Order a sample to your target market. Check photos against the actual item, packaging, tracking, delivery and return route. A waitlist or landing page can test interest, but it cannot prove supplier reliability or profit. Work out contribution after estimated acquisition cost before scaling a test.
Do not manufacture scarcity or collect payment for an item you cannot deliver. If a small test is weak, revise the buyer, offer or price deliberately. A no-go decision can save more than a premature launch. Continue with the niche scorecard to decide whether the broader category is worth building around.
State the strongest evidence for demand, the strongest evidence against it, and the next cheapest test that could change your decision.
