I literally bought this book about 10 minutes ago, and have literally breezed through the pages. It is a very very basic guide to getting more views on YouTube, and states pretty much the obvious i.e. keywords, annotations, using the description box etc.
I guess it's suitable for a novice, but I'm sure the majority of people who search for information to boost their hits on YouTube will know 90% of the tips in this book.
My advice is to save your money, and perhaps spend the extra £8 on a detailed guide because you're not going to get much from this.
I thought I could 'save some money' and grab an instant guide via kindle, but I think a lot of these kindle books are saturated with people trying to make a quick buck by writing short essays and flogging them off on Amazon for the unsuspecting buyer.
Don't get me wrong there are a lot of good e-books out there, just don't expect much for £2 - £3.
