Changing the Amazon main image will affect the weight, but the degree of impact depends on many factors. Whether the new main image can attract more buyers to click and browse will affect the click-through rate of the product. The main image of the product directly affects the buyer's first impression of the product and is closely related to the conversion rate of the product. Whether the new main image can improve the conversion rate of the product will affect Amazon’s recommendation of the product. Different product categories have different requirements for main images. When changing the main image, pay attention to adapt to the regulations of different categories to ensure compliance with Amazon's requirements. When market competition is fierce, changing the main image may be to differentiate yourself from competitors. Whether the new main image can effectively highlight the advantages and features of the product will have an important impact on the ranking and exposure of competitors.
