If you're a freelance marketer or someone with knowledge gaps about selling online (put it this way, if you never sold more than 10 things online in your business) then this book is 100% for you.
It'll give you the big-picture overview about the right way of selling online.
It's not a book about details, but rather the big picture. I think a lot of the negative reviews come from people who probably already have the knowledge.
But for someone who wants a knowledge 'injection' about selling online, this is it. I literally read it on New Years and 7 days later I got my first 2 profitable sales online. I implemented everything using the selling system inside as a checklist.
I made 10 more sales ($200/mo subscription product) after that. Also my ads' click-through rate increased. Really good book for beginners in my experience.
PS, success requires a lot of information and when you'll read this book you'll have some already. If you still struggle after reading it it's probably because you need more information. Don't give up
PPS, oh one more thing... information should come mainly from ACTION not reading or watching videos. Action = results
