Here is a quick overview of the main licenses:

RESELL RIGHTS (RR)

Digital products that come with resell rights allow the holder of the license to sell the product to any market group and retain 100% of the profits.

MASTER RESELL RIGHTS (MRR)

Master Resale Rights enable you to resell the product to your customers along with the basic resell rights that comes with it.  Your customer in turn can also resell the product to their own customers.  Master Resale Rights can be sold with the product or sold separately. You may also be permitted to make changes to the product and set your own pricing. With MRR, one is able to also pass along the rights to sell the product to their own customers.

GIVEAWAY RIGHTS (GAR)

The other type or resell rights is the Giveaway Rights. This basically means that a person may give away the product. There are several reasons why this is can be a good strategy. Giving away a product can create a general buzz about your business and products. It is also a great way to get your name out there in the middle of all of the other businesses. This principle is seen all over, examples in the retail field would be free pens, mugs, and t-shirts that are often given out during advertising campaigns. A big advantage to this type of right is that allows you to give your customers something of value for free. This increases the likelihood of them returning to your website and making purchases from you. You put the giveaway rights in hopes that it will increase traffic and therefore increase leads and sale on your website.

PERSONAL USE RIGHTS (PUR)

There is not a lot you can do with the personal rights only license as these are only meant for your own use. However, there is nothing to stop you once you have absorbed the information in creating a new product that you put together yourself.

PRIVATE (PLR)

PLR license gives you the ultimate rights to do ANYTHING YOU WANT with the product you just bought. This is one of the best type of Resell Rights you could have for a digital product. This allows you, not only to buy the product, but also change the product in any manner you see fit. You can sell the product on its own, you can modify the content, claim authorship, and set your own pricing. The great part is that PLR often offers extended options, including breaking up the content or material, reselling the licenses to others and creating compilations from multiple PLR products. With PLR, you can save yourself from tiring research and tedious work in developing a product. In short, you just created your own products without lifting a finger.
