How do I optimize for thumb-friendly navigation?

As a mobile e-commerce store owner, I'm struggling with user experience on smartphones. My conversion rates are dropping, and I suspect it's because my site isn't optimized for thumb navigation. Users find it difficult to tap buttons, scroll through products, and complete purchases, especially on larger screens. I need comprehensive strategies to redesign my mobile interface to make it more intuitive, accessible, and comfortable for users who primarily interact with their smartphones using thumb movements.
