@Kelheor Yeah, I do get the feeling that these mainly appeal to teenagers and people in their early 20's.
@Calculus_Homework Yay for summaries! I'm also not easily swayed by ads. If it's something I already don't think I'll be interested in, an ad will rarely change my mind. With how many ads we're exposed to daily, it's hard for me to imagine anyone who is swayed by them. There's not enough time or money in the world to engage with every product, so it seems like it would cause endless wanting and depression. Ignoring ads is kind of a necessity. And unfortunately that impacts indie creators, not just corporations.
A few people in this thread + plus some other authors do make their own versions of these ads. I'd guess that most authors make their own, because unless an author is really popular, they don't usually have other people making ads for them. And if a type of ad works, it works, no matter how disingenuous it might feel.
That being said, I get that yucky feeling. It's part of the reason why I don't want to do these (at least not seriously. Maybe as a joke.) When you boil down books to a collection of popular trope names, I feel like there's a risk of any book advertised this way coming off as generic. Like it was made in a lab. It makes it hard to tell a story that was quickly made to cash in on popular trends and one that was made with passion and care.
Technically, all the tropes in the example image apply to my story (though some are misleading), but even if I swapped out some of the more misleading ones for more honest ones, I'd feel bad advertising it this way. I think @/vapidink had the right idea of pairing one of these ads with a summary.
I also love the memes, though. I've seen a Breaking Bad one, an American Psycho one, and I think an Epic of Gilgamesh one?
