I truly love PLR content. Private label rights eBooks and other material can be purchased very inexpensively. Here is one of my favorite sites to purchase these high quality products at a very low price. There are many ways to then monetize it by marketing it online.
One way is to repurpose it into another format. If you purchase a PLR eBook, record yourself reading it and then sell it as an audio product. This will help you to reach a wider audience of prospects. Another way is to rewrite the content, add your own affiliate links, and then give it away to your list.
Using PLR as a bonus to one of your paid products is yet another option. Also, use private label rights materials as content for your membership site. I purchase PLR to add to my membership site every month, and my students have told me how much they enjoy learning from these ready made products.
