What makes you want to buy the book?

Hey everyone

Today I am asking the question: What Makes You Want To Buy A Book? Is it the book cover? I buy books based on book covers. If I think something looks really nice, I go read the blurb.

Is it a book video? I love, love, love book videos but a lot of people argue that they don't sell books. When you see this book video, do you want to buy the book?

How about contests? If I offered you Amazon money or a free read today would you want to buy the book?

I ask these questions because we, as authors, we really have no idea what books will sell and why. None. We can write a best-selling series and suddenly people stop reading. All of our books can languish and then suddenly a short story we wrote fast is eating up the charts. It makes little sense to us. The best we can do is always do our best work and hope. So, I'm asking you today, what makes you buy a book?
