If you're running Amazon Ads or boosting posts with static images, you're paying what I call a "boredom tax."
In 2018, you could slap a book cover on Facebook, target "Stephen King fans," and make sales. Today? The algorithms have trained readers to ignore anything that doesn't move. TikTok, Shorts, Reels—they've turned everyone into video addicts.
When you run a static ad, the algorithm charges you more per click because users scroll past instantly. Your book isn't bad. You're just trying to sell depth in a market trained to reward stimulation.
You don't need better keywords. You need to stop being invisible.
