If your product grid has a high bounce rate, switching to a category-first layout can help. High bounce often means shoppers feel overwhelmed or can't quickly find relevance. Looking at click paths, scroll depth, and search refinements shows where friction starts. If users are leaving because too many mixed products appear at once, grouping by category first can simplify decision-making and improve orientation. But if bounce is driven by poor product relevance or slow load times, a layout change won't fix it. Testing both structures and comparing engagement helps reveal what actually improves flow.
