How to increase the Amazon sales rank?

One of the most important steps in increasing your amazon sales rank would be to win the Amazon Buy Box. This is the white on the right side of the amazon page that gives browsers the option to add a product directly to their cart or purchase a product instantly.

There are three requirements to winning the Buy Box:

1. Professional sellers account: (this can be checked at Amazon Seller Central)
2. Products must be new and unused
3. Product must be available and in stock

Due to the high volume of sellers selling on amazon, it can be quite difficult to achieve the buy box even with all three requirements. Thus, selling high-quality products, having outstanding seller metrics, and having great customer service can set you apart from other sellers.
Other steps to take to increase your amazon sales rank should be:

1. Detail products as much as possible  
   1. Product Type
   2. Brand and description
   3. Product line
   4. Material/key ingredient
   5. Color/size
   6. Quantity
   7. Manufacturer Part Number
2. Offer prime
