Private Label Rights (PLR)
Private Label Rights are the best… You can sell it as is. You can use it for content for your website. You can edit it, change it, or add to it for a unique product, or even use a content spinner. You can break it apart and use it however you want. You can claim authorship after rebranding or changing it. Basically the freedom to do with a product as you see fit if the license allows.

Master Resell Rights (MRR)
Master Resell Rights allow you to resell the product with offering the same rights or resell rights to your customers upping the value of the product.

Resell Rights (RR)
Resell Rights allow you to resell the product but often only allow you to offer personal use on to the next customer.

Give Away Rights (GAR)
Give Away Rights might allow you to give the product away as a bonus, and / or package it with other products for higher resale value, and / or give it away freely. These are good rights as you can make a package unique by putting products together that no one else is offering. You can also gain subscribers by offering this type of product if the license states you can. Read the license to see how you can give it away. PLR Planet has many products with these amazing rights.
