As a reader, how do you buy a book? The cover catches your eye maybe and then you read the title. If so far so good, you read the teaser or the excerpt like most people do. If you really want to know if it’s the one, you turn to a random page and look for something to grab your attention. If nothing is there, you try again. You really want to read a good book. Now, if you were the author and you wanted to sell your book you would be wise to get this readers attention and do it quickly. Lot’s of people just bought new smart phones. About 75% of young people aged 17-34 have them and they want to do cool things with them such as download an app and watch your book trailer or read your random exciting page from some encrypted QR code. Any reason to take that awesome new phone out. You should get wise to this. It doesn’t matter that you don’t use a smart phone or know how to scan a QR code. What matters is that the time is right to capitalize on the hot tool people are actually using.
