To quickly promote new products on Amazon, you first need to establish a detailed marketing plan. This includes analyzing target customers, developing attractive product descriptions and pictures, optimizing keywords and search rankings, and establishing customer feedback and reviews.

Secondly, you need to use Amazon advertising, including Sponsored Products, Sponsored Brands, and Sponsored Display, to increase exposure and click-through rate.

You also need to use channels such as social media platforms to expand your visibility, attract users to buy through discounts, promotions, gift cards, etc., and promptly handle customer feedback and after-sales issues to improve user satisfaction and loyalty.
