PLR stands for Private Label Rights. A PLR product or service is created by one party and distributed with permission by another party under the distributing party’s label or business name. There are many working examples of this concept in the offline world: For instance, a company called Vitarich Laboratories manufactures health supplements and sells packaging and labeling rights to many well-known vitamin retailers like GNC. In this scenario Vitarich Labs produces the vitamins, minerals, etc. and GNC bottles these products, slaps a great looking label with their logo onto each bottle, then stocks the shelves of their international retail centers with GNC branded supplements.
Another example is Chef Boyardee canned pasta. Surely you’ve had a can or two of their Ravioli or Spaghetti & Meatballs at some point. In an effort to generate even more revenue for their already profitable company, ConAgra Foods, Inc. (the producers of Chef Boyardee products) has numerous PLR packaging contracts with grocery store chains and smaller canned food manufacturers and distributors. So the products are cooked and canned at the Chef Boyardee plant but labeled with the brand name and logo of the PLR partner, Save-A-Lot groceries being just one example off the top of my head. So you see the concept of Private Label Rights is actually far older than Web marketing, and in fact even predates the Internet! But the concept has gained a great deal of mainstream popularity in the online marketing communities over the past couple of years. In the case of Web marketing, PLR is often seen with e-books, software, etc. where the initial creator of a product sells (usually a limited number of) licenses to distributors allowing them to not only retail the product under their name and logo, but even alter the contents and functions of the product considerably if they wish.
