Since most web traffic now comes from mobile, optimizing for it is a must. Focus on these mobile CRO must-do’s Optimize images, enable caching, and use a fast-loading theme to keep users from bouncing. Keep forms short and easy to fill out.. Use sticky CTAs. Make sure important buttons are always within easy reach. Optimize checkout for one-click payments. Have support Apple Pay, Google Pay, and autofill options. Finally, be cautious with pop-ups. Google penalizes intrusive ones, and they frustrate mobile users. If you use them, keep them subtle and easy to dismiss.
