Just out of curiosity, what makes you want to pick up a book or ebook, whether from an author whose work you are familiar with or someone you're not? Do random ads make you want to buy a book? Do posts on social media ever make you check out a book or author?
I'm looking to try new promotion avenues to increase book sales.
Posts on social media definitely have whetted my curiosity about particular books, time and time again; and I've bought, or at least read, a number of books just because of that. (And there are a lot more books that I want to buy or read for the same reason.) Ads, on the other hand, don't interest me; I figure they come from people who have a vested interest in manipulating me, and I don't feel like cooperating with them. I've never bought a book just because of an ad.
