What role does mobile-friendly design play in landing page CRO?

Mobile-friendly design is crucial for conversion rate optimization because most of the traffic now comes from smartphones. If your landing page isn’t optimized for mobile—slow to load, hard to navigate, or with poorly placed CTAs—users are more likely to bounce. A responsive layout, fast load times, readable text, and thumb-friendly buttons improve the mobile experience, reduce friction, and increase the chances of conversion.
