Here are some of my thoughts on rewriting PLR:
-Change the cover. It may seem trivial, but it is the most important. I once saw someone here on warriorforum selling some ebooks and after I purchased them I found out that they were not his own ebooks but they were PLRs (true story). I even started a thread here on warriorforum. I finally got a refund because he didn't have the right to resell PLR rights. It was so easy to recognize them from the cover. if he had changed the cover I wouldn't have noticed it.
-Changes should also be made to the overall look of the eBook. The new eBook can be significantly distinguishable by changing color schemes, font and spacing on the cover and throughout the material. It is also important to change the format. Most PLR eBooks are text documents with very little formatting. formating will make your ebook more unique and look more professional, and makes the eBook more appealing and appears more valuable. Also good formating makes it easier for customers to read.
-Change the title. It's the easiest thing to change. It may seem obvious but believe me it is often overlooked. I think it is the most significant change to make to a PLR eBook.
-Rewriting the Content. I don't have much experience on this. But I usually read a whole paragraph understand what it says and then try to write it again without looking.
How do you make your PLR eBooks unique?
