Even with a great product and solid traffic, many eCommerce stores fail to generate sales. The problem is often not the product it’s the design.

If your store is built on Shopify, avoiding common design mistakes is critical. Small issues in layout, speed, or user experience can quietly destroy your conversion rate.
