Introduction
Conversion Rate Optimization (CRO) tools help businesses increase the percentage of visitors who complete a desired action—such as making a purchase, signing up, or submitting a form. Instead of focusing only on bringing more traffic, CRO tools help you maximize the value of the traffic you already have.
