Why Comps Matter When Publishing a Book

I hear authors complain all the time. Why do I have to list comps? Why can’t my book just be my book? It isn’t like another book! And I get why this is problematic for many authors and one of the hardest parts of querying. But finding comps is not just necessary for the querying process. It is essential in the marketing as well. Asking “What other books are like mine?” will help sales and visibility more than authors realize. I hope this article helps you understand the importance of comps and how you can use them in your marketing and querying.

Comps are books that share meaningful similarities with your manuscript. They might have a similar genre, audience, tone, premise, setting, or reading experience. Good comps help publishers, agents, booksellers, marketers, and readers understand where your book fits in the marketplace. They are not about proving that your book is exactly like another author’s book. In fact, your book should have something that makes it different. Comps are about giving people a frame of reference.

And when you’re trying to publish a book successfully, where your book fits matters enormously. Imagine an author submits a manuscript and describes it as:

“A fantasy about a young woman who discovers a dangerous secret.”

That could describe thousands of books. Now imagine the author says:

“This is a dark romantasy with the political intrigue of one popular title and the enemies-to-lovers tension of another.”

Suddenly, the publisher has a much clearer picture. Comps communicate genre, tone, readership, and commercial positioning much faster than a lengthy description can. For a publisher evaluating a manuscript, this information is valuable because publishing isn’t simply about whether a book is good.

A book can be beautifully written and still be difficult to sell if its intended audience is unclear.

It’s similar for publishing a book. Publishing means finding readers who want that particular kind of book. If your book is a cozy mystery, your potential readers are probably already reading cozy mysteries. If it’s a psychological thriller, your audience is likely reading psychological thrillers. Your comps can help identify that audience.

Look at the readers who enjoyed the comparable titles:

What other books do they buy?

What tropes do they respond to?

What covers attract them?

What language do publishers use to describe those books?

What retailers categorize them together?

What authors do those readers already follow?

This information can influence everything from the cover to the back-cover copy to the marketing strategy.

Positioning is one of the biggest reasons comps matter. Consider a book that contains romance, fantasy, and political intrigue.

It could potentially be marketed as:

fantasy romance

romantasy

epic fantasy

political fantasy

romantic fantasy

Those categories attract different readers. The right comps can help determine which description makes the most sense commercially. That’s important because readers shop by expectation. When a reader picks up a book because they loved a particular comparable title, they’re expecting a certain experience. If your book delivers that experience while still offering something fresh, you’ve created a strong connection between the reader and your book.

One of the biggest mistakes authors make is choosing comps based only on plot.

For example:

“My book has dragons, so my comp is Fourth Wing.”

That’s not necessarily enough. A useful comp should ideally tell us something about the current readership and marketplace for your book.

Think about:

Genre

Subgenre

Target audience

Tone

Themes

Tropes

Reading experience

Market positioning

Recent sales potential

A book doesn’t have to have the same plot to be a good comp. In fact, sometimes a book with a completely different premise is a better comp because it attracts the same type of reader.

Another important consideration is how old the comp is. A massive bestseller from 20 years ago might demonstrate that readers have historically loved your type of book. But it may not tell a publisher much about what is commercially working right now. That’s why recent comps are often more useful. A strong comp list might include books published within the last few years, particularly books that are succeeding in the current market.

This gives publishers information about current:

Cover trends

Reader expectations

Genre trends

Pricing

Marketing

Retail placement

Competitive titles

The goal isn’t to chase every trend. It’s to understand the environment in which your book will be competing.

Another common mistake is using only enormous bestsellers as comps. Saying your debut novel is comparable to Harry Potter, The Hunger Games, or A Court of Thorns and Roses may sound impressive, but it doesn’t necessarily help a publisher understand the book’s realistic position in the marketplace. Those books have enormous brands, established fan bases, extensive marketing, and years of accumulated sales.

A better strategy is often to identify books that are successful but realistically comparable.

If a book published recently by a debut or relatively new author is performing well with a similar audience, that can be extremely useful. It demonstrates that readers are currently buying that type of book.

Perhaps one of the most valuable things comps can do is reveal a problem before you spend money publishing the book. Suppose you can’t identify any recent books that resemble your manuscript. That doesn’t automatically mean the book is bad.

But it should make you ask questions.

Is the genre difficult to define?

Is the concept too unusual for the intended market?

Is the audience too small?

Is the book combining genres in a way that makes it difficult to position?

Or is the author simply looking in the wrong places?

Sometimes the research reveals an exciting opportunity.

Other times, it reveals that the book may require a different positioning strategy.

Finding that out before publication is much better than discovering it after you’ve paid for editing, cover design, printing, advertising, and distribution.

Comps are also extremely useful for cover designers. A cover designer needs to understand what readers expect to see when they shop for a particular type of book. Look at the covers of your strongest comps. What do they have in common?

Maybe they use:

Certain typography

Particular colors

Specific imagery

Illustrated characters

Photography

Minimalist design

Dark atmospheric artwork

Those similarities aren’t accidental. They are visual signals that tell readers, “This is the kind of book you like.”

Your cover shouldn’t simply copy another book. It should be recognizable as belonging to the same market while still being distinctive. A beautiful cover that doesn’t look like it belongs in its category can actually hurt sales.

Marketing becomes much easier when you know exactly who you’re trying to reach. If your book has strong comps, you can investigate where fans of those books spend their time.

You can look at:

BookTok

Bookstagram

Goodreads

Facebook groups

Reddit communities

Genre newsletters

Book bloggers

Podcasts

Influencers

Advertising audiences

You can also study the marketing strategies used by comparable books.

What language appears in their advertisements?

What tropes are emphasized?

What keywords appear repeatedly?

What kind of promotional campaigns are they running?

Your comps essentially become a research roadmap. A strong comp section demonstrates that an author understands the marketplace.

It says:

“I know what I’m writing, I know who will read it, and I understand where it belongs.”

That’s a much stronger position than simply saying, “Everyone will love this book.” No book is for everyone. The goal is to identify the readers who are most likely to become passionate about it.

Ultimately, a good comp does more than say, “My book is like this.”

It helps answer:

Why would the reader who bought that book want this one?

Maybe it’s the same emotional experience.

Maybe it’s the same trope.

Maybe it’s the same audience.

Maybe it offers a familiar premise with a new twist.

Maybe it combines two popular elements in a fresh way.

That’s where comps become powerful. Authors understandably focus on writing the best book they can. They should. But publishing requires another skill: understanding the marketplace.

A publisher has to answer questions like:

Who will buy this?

Where will we sell it?

How will we describe it?

What shelf does it belong on?

What cover will attract its readers?

What other authors can we compare it to?

What audience should we target?

How do we convince a reader to choose this book?

Comps help answer many of those questions. That’s why they matter. A strong manuscript with strong comps gives a publisher something extremely valuable: a clear path to the reader. And ultimately, that’s what publishing is about. Not simply putting a book into the world. Putting the right book in front of the right reader. This is why comps are important. And why they deserve careful thought.
