Why the Book Ad Targeting Advice Fiction Authors Keep Hearing Is Wrong (Part 2)
There is a piece of targeting advice that gets repeated constantly in author communities, on YouTube, in Facebook groups, in courses, and in coaching programs. It sounds logical. It is easy to follow. And for most fiction authors, it quietly makes their ads worse.
This is Part 2 of a two-part series on book ad targeting for fiction authors. Part 1 covered who your audience actually is, the mindset shift that changes how targeting decisions get made, and the three barriers that stop most authors before they ever run a single ad. This post covers why the most commonly repeated targeting advice is working against the authors who follow it.
The Also-Boughts Problem
The advice in question: look at your also-boughts and use those authors as your ad targets.

How Fiction Authors Should Actually Determine Their Book Ad Audience (Part 1)
Whether just getting started with paid ads or already running campaigns that seem to disappear into the void, there is one thing author coach Rebecca Hamilton sees trip up fiction authors at every level: they don't actually know who their book's audience is.

...Facebook Ad Targeting for Fiction Authors in 2026
One of the most frustrating moments for fiction authors running ads is realizing that the exact author you want to target… simply isn’t available. This happens constantly on platforms like Facebook Ads. An author may be dominating bestseller lists, trending on BookTok, or selling millions of copies, and yet they don’t exist as a selectable targeting option.

This misunderstanding often shows up alongside other performance issues authors attribute to broken ads, even when the underlying systems are functioning exactly as designed, a pattern explored further in Why Most Authors Think Their FB Ads Are Broken in 2026 blog post.
The good news? If an author isn’t targetable, their readers almost always are. just under different signals.
