Comp titles are the cheat sheet for nearly every publishing decision you'll make — and most indie authors either ignore them or pick them wrong. Get them right and your cover, blurb, categories and ads all fall into place.
What a comp title actually is
A comp (comparable) title is a recent, successful book that appeals to the same reader as yours — not just the same topic, but the same taste. Your comps are the books your ideal reader has on their shelf already. They tell you, with hard market evidence, what works for that reader.
Why they drive every decision
Get your comps right and they answer the questions indies usually guess at:
- Cover — what visual style signals your genre to your reader? Comp covers show you. (See hiring a cover designer.)
- Blurb — what promise and tone do these readers respond to? (See book description writing.)
- Categories and keywords — where do your comps sit, and what terms describe them?
- Ads — who to target: readers of your comps. On Facebook you target comp-author interests; on Amazon you target comp ASINs.
- Pricing — what your reader expects to pay for a book like this.
How to find them
- Amazon also-boughts and "Customers who bought this also bought" — the most honest signal of which books share readers.
- Amazon category bestseller lists — browse the exact sub-category you'll publish in; those are your competitive set.
- Goodreads "Readers also enjoyed" — taste-based, not just sales-based.
- BookBub — featured deals in your genre show what's actively selling.
How to pick the right 3-5
- Recent — last 2-3 years. Old comps mislead on current cover and pricing trends.
- Same audience, not just same topic — a literary novel about grief and a cosy mystery about grief share a topic, not a reader.
- Selling well but not mega-bestsellers — you want achievable comps (mid-list winners), not Lee Child. Comping to a megaseller tells you nothing useful.
- 3-5 is plenty — enough to see the pattern, few enough to act on.
Then reverse-engineer: what do all five covers have in common? What does every blurb promise? That pattern is your brief.
Frequently asked questions
What are comp titles?
Comparable titles — recent, successful books that appeal to the same reader as yours. They guide your cover, blurb, categories, keywords and ad targeting.
How do I find comp titles?
Amazon also-boughts and category bestseller lists, Goodreads "readers also enjoyed," and BookBub deals in your genre. Pick books with the same reader, not just the same topic.
How many comp titles do I need?
3-5 well-chosen ones. Enough to see a clear pattern in covers, blurbs and categories, few enough to act on.
Should I comp to bestsellers?
No — comp to recent mid-list winners selling well in your exact sub-category. Mega-bestsellers are unachievable benchmarks that tell you little about your realistic market.
