E-Commerce Insights: Use Online Testing to Increase Print Catalog Response Rates

2. Use online testing to determine product breadth. Should you sell the single best product in each product category? Should you present a three-level, good/better/best selection in each category? Or should you sell every SKU your merchants can source? This is a big question with big implications and different answers for every retailer. You can use online testing to run head-to-head tests of product selection. If tests across different categories yield similar results, you can take those insights back to your paper pagination.
