Signs that customers value the product
Signs include strong retention (customers keep returning), recommendations without prompting, willingness to pay, and customers saying they would miss the product if it disappeared. Together, these suggest demand beyond constant promotion.
Fit can change
Fit depends on the product, the customers it serves, their needs, and the market. A product may fit one group but not another. Rapid growth from discounts or advertising does not prove people will keep using it.
Teams weigh usage, revenue, and customer feedback rather than relying on one survey. They keep checking because competitors, customer expectations, and the product itself can change.
