I would not recommend spending money on this book. Though it is well written, any author who has already looked into promoting their books will find the majority of the book of no use. However, someone wanting a quick pit-stop to making additional sales may find this a handy quick reference.
This book also gave me the impression it was written to promote to the readers expensive courses that the author self-hosts. I’m all for online courses, but not when the creator’s book on similar subjects failed to wow me.
The only highlight for me was the suggestion to think of cruise ships as opportunities to sell more books, which was a suggestion I hadn’t come across before.
