Your store has traffic. You have products people want. But conversion is lower than it should be, the back-end is increasingly difficult to manage, and no one can give you a clear answer on what is actually holding the business back.
The problem in most cases is structural. Stores that grow organically accumulate decisions: category structures that made sense at 200 SKUs but break at 2,000; product data that varies in quality across the catalogue; navigation logic that works for the team who built it but not for the buyer trying to find something. More spend on top of a broken foundation produces more wasted spend.
