Did you know that most eCommerce stores see conversion rates between 2-3%? This means that for every 100 visitors, only a couple actually buy something. That's a lot of potential revenue left on the table. Improving your conversion rate (CRO) is critical for eCommerce success, and it takes a smart, multi-faceted approach. This guide is packed with resources to help eCommerce managers and digital marketers optimize their websites and boost sales. I've focused on resources you can actually use.
