I received a free copy in exchange for a review.
Firstly. The book is extensive. 200 Pages filled with various things on Instagram, not only explaining the marketing and how-to's, but the whole terms that are used in Instagram. From Picture Size, to demographics, up to what color should you use, it's all there. There was literally 2 pages on terminologies for Instagram in the first pages.
This book is especially useful for beginners, not to say experts don't, but they're useful for newbies because it's really detailed. It uses real-life examples (sometimes even said author's experience), tips on how to make it work, what programs you should use, to what an example schedule posting should look like.
As far as black-hat methods go, there is nothing here. You can't find that sweet how-to bot methods and the likes in this ebook. It focuses more on building long-lasting accounts and building trust with your followers. In other words, it's as whitehat as it goes.
So. Does it work? Isn't that the question. As the saying goes "actions speak louder than words," this whole ebook is useless if you don't act on it. The guide is here, all written out, and you only need to work on it. Follow the steps, maybe be creative with it. Who knows? You might find success with it soon.
Overall one of the more detailed ebooks out there, I can say that this one is definitely worth the price. I recommend this product.
