I just published my third book( indie publishing) and I do not *sell* books as a result of my social media posts…but I do share myself. I feel that by sharing my work and the reviews and my writer’s experience.. I engage people who might not lean toward buying a book but will gain a perspective or bit of who I am and my experience and values. I am a relatively new author but KIRKUS REVIEWS magazine picked up one of my books two weeks ago. I’m going through a slow grind to build this career and I hope investing in reviews will help. Social media doesn’t sell books. I’m glad I know that. Thanks for confirming.
