Book marketing statistics

Book marketing statistics for 2026

The most useful book marketing statistics for 2026 show that Amazon dominates ebook sales, social posts move only a small share of followers, and list building should start about 90 days before launch.

Book Profits Club gathered these published figures from industry guides so authors can plan with real numbers. None of them are Book Profits Club results. Together they explain why the club teaches authors to own their reader relationship and connect the book to an offer.

What do book marketing statistics tell authors?

They point to one conclusion: do not rely on a single channel you do not control. Amazon handles 80% of ebook sales, and only about 0.25% of followers act on a typical post. Your email list and your offer are the parts you own.

Each figure below names its source. Follow the links to read the original context before you rely on a number.

What these numbers mean for your book

Own the relationship

With most ebook sales on one retailer and social reach controlled by platforms, an email list is the one audience you keep. That is why Book Profits Club treats the list, started about 90 days before launch per Forbes Books, as the center of a book marketing strategy.

Small audiences can be enough

Low engagement rates are normal, so a modest following is not a failure. When your book leads to a coaching offer, a few engaged readers who become clients can matter more than thousands of passive followers.

This guide is part of our complete book marketing strategy for authors, which shows how every piece fits together.

Common questions

Where do most self-published ebook sales happen?: Amazon. Ulatus reports that 80% of ebook sales still run through Amazon. That makes your Amazon listing, reviews, and categories important, but it also means you do not own the customer relationship there. An email list and your own offer give you a direct line to your readers.See this in the full FAQ
What is a good social media engagement rate for authors?: BookLaunch’s analysis says an engagement rate between 0.02% and 0.09% is considered good, 0.09% to 0.33% is high, and anything over 0.33% is very high and rare. Low numbers are normal, which is why authors should use social media to start relationships and then move them to email.See this in the full FAQ
Is the book market growing?: The market is large but uneven. Ulatus cites a global book market of $142.72B in 2025 and reports that print sales dipped 0.9% in the first nine months of 2025. Citing Publishers Weekly, it adds that adult fiction fell 1.3% while romance rose 7% and science fiction rose 12.3%.See this in the full FAQ
When should I start marketing my book?: Earlier than most authors expect. Forbes Books suggests building your email list about 90 days before launch, and ManuscriptReport recommends researching reviewers 3 to 4 months before publication. If your book is already out, start today with an email list and a clear next step for readers.See this in the full FAQ
Is selling 5000 copies of a book good?: For most self-published authors, 5,000 copies is a strong result, though what counts as good depends on genre, price, and goals. If each copy earned $3, that is about $15,000 in royalties. If even a small share of those readers became clients, the book’s total value could be much higher.See this in the full FAQ
Do I need a big following to sell books?: No. Because only a small share of followers act on any post, a small engaged audience that joins your email list can be worth more than a large passive one. If your book leads to a coaching offer, you need relatively few clients to reach a meaningful income goal.See this in the full FAQ
