It's not that BooksGoSocial didn't try, but I doubt that they were actually able to do anything for my book (a nonfiction book). They have a lot of followers but I suspect they are all authors wanting promotion for their books and not readers who want to buy books. I rewrote my book description following the BooksGoSocial's instructions. I tried to get people to review my book, but was shot down by BooksGoSocial when I did what his post had asked authors to do. I tried some of the other free things that they offer/suggest. My book was increasing in sales before I used BooksGoSocial (10 paperback sales the first month and 20 the second - the BooksGoSocial promotion came after the 20 sales of the second month) and now it is not selling (I had 2 sales the third month and none so far this month). (I should say that my Kindle sales have stayed the same at about 10 a month). My book's paperback rating on Amazon has nosedived into the netherworld. Lessons have been learned and I am moving on.
