Start with a buyer problem, not a viral product list. Gather repeated questions and complaints, compare how existing sellers solve them, then screen candidates for differentiation, supplier reliability, delivery, returns and margin. A product is a test candidate only after those checks—not a guaranteed winner.

Listen for a job people already pay to solve
Write down the exact words customers use in reviews, forums, search suggestions and support questions. Look for recurring annoyances rather than isolated praise. A compact desk lamp, for example, may be interesting not because lamps trend, but because renters repeatedly struggle with glare and limited space. Shopify's product-opportunity guide recommends combining demand signals, competitor gaps and financial viability.
Build a shortlist you can compare
For each idea, record the buyer, problem, current alternatives, price range, landed supplier cost, shipping time, likely returns and your credible difference. Reject candidates you cannot describe honestly or source consistently. Competition alone is not disqualifying; it can prove demand. The useful question is why a buyer would choose your offer over a familiar one.
Treat trend charts carefully
A social spike can be a clue, but it may end before your supplier and store are ready. Check whether searches and marketplace reviews persist across weeks or seasons. Read negative reviews for unmet needs, but do not copy a rival's listing or assume its visible sales equal profit. Order a sample before writing claims about size, quality or delivery.
Fill a three-product research grid
Give each candidate one row with seven columns: buyer, problem in the buyer's words, current alternative, your provable difference, landed supplier cost, delivery and return risk, and next validation test. A product is not ready because every cell has a positive answer; it is ready for a small test when the unanswered cells are explicit and affordable to investigate. For example, a compact lamp with clear demand but no verified electrical safety information should not move to an ad test. A less exciting desk organizer with a sampled supplier and positive contribution might be a stronger first experiment.
The next step is product validation with evidence from real buyers. If no one can explain a distinct reason to purchase your version, do not pay to advertise it yet.
Shortlist three candidates and give each a one-sentence buyer problem, a differentiating promise you can prove, a supplier quote and a rough contribution margin.
