What does the conversion rate measure in UX design?

The conversion rate is an essential metric in UX design because it quantifies the effectiveness of a particular design or interaction in guiding users toward completing a desired action. This desired action could be anything that aligns with business goals, such as making a purchase, signing up for a newsletter, or downloading an app.

By measuring the percentage of users who achieve this action out of the total number of visitors, designers and stakeholders can assess how well the user experience facilitates engagement and encourages user behavior that leads to these conversions. A higher conversion rate typically indicates that the design elements, messaging, and overall experience are resonating with users, whereas a lower conversion rate may point to issues that need to be addressed to improve the user journey.

Other options, while providing insights into user behavior, do not directly measure the effectiveness of achieving specific goals related to user actions, which is the primary focus of measuring conversion rates in UX design.
