The methods and skills for selecting products on Amazon are as follows:

Market-oriented method: Product selection must be based on market demand and explore potential consumer products in the market. The Best Sellers two-stage selection method can be used to quickly select products that have been tested by the market.

Related recommendation selection: If you have found a hot-selling product A, you can consider digging deeper into the accessories or related products around this product A, such as developing other colors, packaging, etc.

Best-selling peripheral selection: If there is a hot-selling product B, you can consider digging deeper into the accessories or related products around this product B.

Supplier recommendation: Not only sellers need to have a keen sense of market demand and insight into the market, but suppliers in many industries also need to have these qualities, and they are not inferior to sellers. Sellers can communicate more with suppliers in various industries, and perhaps they can get different product selection information from them.

Google Trend Analysis: Use Google's data analysis tools to analyze industry trends and internal operating conditions, and dig out valuable information to provide sellers with product selection references.

I hope the above information is helpful to you.
