Your main product image on Amazon matters more than the product itself when you're starting out. In mobile browsing, it's what makes shoppers stop scrolling and click. Spend 90% of your listing effort on the main image and gallery, 10% on everything else.
When you're first starting Amazon FBA, your main image matters way more than the actual quality of your product. Sure, you don't want to get 1, 2, 3-star reviews, but as long as you have a steady 4.5-star review rating on your actual product, the main image is the most important, especially in this time where people are scrolling with their thumb. You want to be able to have someone's thumb stop because of your main image. So So focus more on main images and listing images more than anything else. It should be 90% main image that you're going ahead and optimizing and 10% everything else when you're first starting on Amazon.
