When it comes to mobile,how would you define usability?

Usability, especially in the context of mobile, refers to how easy and pleasant it is for a user to interact with your website or application. This encompasses the user's overall experience, including ease of navigation, readability, functionality, and how quickly they can achieve their goals. A good user experience (UX) leads to higher engagement and conversions. While the visitor's time navigating your site or general time on your site are components that can influence usability, they don't fully define it. A user might spend a long time on a poorly designed site due to frustration, not enjoyment. Therefore, the comprehensive "experience" is the most accurate definition.
