The Amazon CPC starts at 81 cents. Compared to other starting CPCs advertisers pay (Google ads 2.32 and FB ads 1.72) that’s a bargain.
But that’s just the starting point. The Amazon CPC is typically relative to the cost of the product. For example, if your product is a $10 hair band, you don’t want a $4 CPC.
As a comparison, here’s a look at average cost per click costs for ads in various service industries:
Consumer services 3.77
Legal services 5.88
Auto services 1.42
In short, a good CPC is a cost that’s inline with the overall cost of your product.
