What does free private label rights mean?

SOURCE: WIKIPEDIA.ORG



Private label rights is a concept used in Internet Marketing and derived from private labeling. It's a license where the author sell most or all of the intellectual property rights to their work. The license is defined by the author of the work and has no legal definition.
Similar licenses include resell rights, also used in Internet Marketing.
Use

The license is used for various digital products such as articles, ebooks, software, graphic templates etc. Because there are many buyers of the same product, the price of a single unit is generally lower than if one would create a similar product from scratch (either by himself or by outsourcing). However, people can also purchase private label content that is limited in distribution, minimizing the number of competing marketers using the same content.
Private Label Content comes in many different formats, including PLR reports, ebooks, articles, graphics, templates and even videos.
While licenses differ with each author and seller, the basic premise is that the license permits buyers to re-brand the content under their own name and brand (excluding copyright). In general practice this means that the product can be modified, sold, resold or repurposed in many different formats. In some cases authorship on the original product is allowed and with unrestricted private label, buyers are often able to resell the same rights they've acquired although not all private label releases offer or permit license distribution or transfer.
Marketers use private label products for reselling under their own brands or in the case of written products for online marketing through channels like article directories, content syndication, ebook directories, slide-sharing websites and similar.
Private Label Content comes with different rights depending on the developer so it's important to thoroughly check each license prior to use, to become familiar with any restrictions that may be in place.

You are best mixing them up a bit and putting your own spin on them, as it is likely that many others will also have these articles...and yes, once you have bought the rights from the author or otherwise acquired them from wherever you can keep all the profits if you manage to sell anything

Yes. You can even build your own brand around the white label version of the digital product and sell that.

Note: Some digital products that come with private label rights prohibit some actions. For example, some private label rights products will state it is okay to give the product away to your email list for free while other products will state that it is not okay to do that.

Usually private label rights products include a section that explains what you can and can't do with the product.
