What is the proper way to post reviews of my books on my web site? Do I ask the reviewer for permission? Once, or every time I post their review anywhere? Can I just take part of it or do I have to copy the entire review? How do I attribute the reviews, or don't I have to mention names? I have some reviews from Amazon and Goodreads, and also one paid review, and I don't know how to convey that information to my web site. Thank you!
