I don’t have much knowledge about it, to be honest, but I am aware of one reputable website where I have been paid for reviewing books myself. If I recall correctly, the website is called Kirkus. Kirkus hires freelance book reviewers to contribute reviews for their website and pays for each accepted review.There are plethora of people that are making money online through writing reviews of books. A number of platforms, including OnlineBookClub.org, NetGalley, and Reedsy Discoveries, provide chances for book reviewers to earn money.
