Use Review Velocity as a Trending Product Signal

Review velocity — the rate at which new reviews come in — is an underused signal for identifying trending products. A product that normally gets 5 reviews per week suddenly getting 20 means demand is spiking. Act on this signal before your marketing data catches up.

Monitor review velocity across your catalog weekly. Products with accelerating review rates should get promotional priority: feature them on your homepage, increase ad spend, stock up on inventory. The reviews themselves tell you why demand is spiking — read them for insights about what is driving interest.

Review velocity also predicts problems. A sudden spike in negative reviews signals a quality issue, a supplier change, or a seasonal mismatch before customer service tickets pile up. Catching these signals early lets you pull products, update descriptions, or add warnings before the damage spreads.

Combine review velocity with review sentiment for a complete picture. High velocity plus positive sentiment equals a product you should be pushing hard. High velocity plus negative sentiment equals a product that needs immediate attention. Low velocity on a mature product may mean it is time to refresh the listing or run a review collection campaign.
