What’s the best way to find new products to sell on Amazon.?

I recently listed a new item which hasn’t been getting too many sales I just want to be able to add some more effective items.

TIA

Hunt products with lower BSR

As mentioned by @Muhammad, the higher the BSR and the fewer the competing offers, the better.

I scan all the products or look them up in SellerAMP.

Depends on your business model tbh. For arbitrage you can start by looking at the deals section on keepa. For private label use helium 10 to identify popular search terms in a specific niche
