Walk into any bookstore, and you’ll see thousands upon thousands of book spines staring at you.
For the average person who is “looking for a good read,” that means they’ll be scanning titles to see which ones appeal to them (usually with their head cocked to the left, to read those titles).
When they come across one that sounds interesting, they’ll pull it off the shelf and examine the cover.
What do they do next?
You guessed it: they flip the book over and read the back cover blurb.
A similar experience takes place online, too, although readers are often seeing the cover and title at the same time. But, once they find a book that looks interesting, they click on it and look for the back cover to read the blurb.
