Conversion rate optimization

A bar chart showing three stages in a "sales funnel": "saw the advertisement" -> "clicked the advertisement" -> "bought the product". The three stages have two conversion rates to be optimized.

Conversion rate optimization (CRO) is the systematic process of increasing the percentage of users or website visitors who complete a desired action, such as purchasing a product, subscribing to a service, or submitting contact information.

CRO is widely used across digital platforms including websites, mobile applications, and online marketing campaigns.
