What Niches Should You Target For Amazon Affiliates?

Today, I'm going to reveal the 4 most profitable niches on Amazon Affiliate Marketing.

1. Mobile Phones
2. Popular Electronics
3. Home Appliances
4. Power tools

The sale price must be at least $100 or more.

1. Should be a popular brand
2. Should have good customer reviews
3. Should have multiple Sellers selling the product
4. The product has at least 5, preferably more, positive reviews with at least a score of 4-5 stars. If the last 3 reviews are all positive with a min of 4 star reviews. 
5. 3 ½ is acceptable as long as they are all positive.

These are the criteria I looked out for when searching for a good amazon niche.
