Mobile optimization is a key aspect of CRO, especially as a growing number of users engage with websites on mobile devices. A mobile-optimized site enhances user experience, which in turn can significantly increase conversion rates. For example, optimizing forms for mobile use, such as changing the default keyboard to a numeric keypad for phone number fields, makes it easier for users to interact with your site. This attention to detail in mobile design not only improves usability but also supports the overall effectiveness of your CRO strategy.
