Conversion Rate Optimization Guide

Conversion rate optimization (CRO) is the process of improving a website to increase the percentage of visitors who complete a desired action. This action could include filling out a form, making a purchase, booking a consultation, or signing up.

Instead of increasing traffic, CRO focuses on improving performance of existing visitors.

Why Conversion Rate Optimization Matters

Increasing conversion rate has direct business impact.

Conversion Rate Formula

Conversion rate is calculated as:
