If you are selling "low consideration" products, meaning items priced under $35 and don't require in-depth market research, it's reasonable to assume that most of your purchase decisions are made on mobile devices.
Therefore, the appearance of your product listing and store on mobile devices needs to be of the highest quality to increase conversion rates and maximize sales.
Recently, Amazon introduced the option to customize different designs for mobile and desktop views. This gives you the opportunity to design your mobile store appearance at a professional level, distinct from what it was before when Amazon simply adapted the desktop images for mobile, which didn't look good.
Go to your store editor and find the option to customize it differently for mobile, and design your store accordingly.
From my experience, this significantly increases the conversion rates of your store.
