The most reliable way to market a self-published book is to build an email list of interested readers, gather honest early reviews through advance reader copies (ARCs), and then use price promotions, ads, and social media to reach new readers. No single tactic works for every book. Most authors see results from steady, repeated effort across a few channels rather than one big push.
This guide explains each method in plain terms, along with the rules you need to follow. Results always vary by genre, book, and timing, so treat every tactic as a test.
Marketing makes more people look at your book. It cannot fix a book that does not appeal to its readers. Before you spend money, check the basics:
Cover: does it look like other popular books in your genre at thumbnail size?
Description: does the first line hook a reader and make the genre obvious?
Sample: are the opening pages clean, edited, and gripping?
Series links: if it is a series, can readers easily find book two?
If ads bring visitors who do not buy, the issue is often the cover, the description, or the price.
An email list is the one marketing channel you fully own. Social platforms change their rules. Stores change their search results. Your list stays with you.
Written Word Media's 2025 Indie Author Survey, based on 1,346 responses, says the size and use of an author's email list is the one metric that most consistently predicts higher author income. Authors with a list reported a median of about $300 a month, compared with about $15 a month for authors without one.
Choose an email service that lets readers sign up and unsubscribe easily.
Offer a reason to join, such as a bonus chapter, short story, or checklist.
Put a sign-up link at the back of every book, right after "The End."
Add the link to your website and social profiles.
Follow anti-spam laws where you live, such as including a clear unsubscribe link.
A short welcome series that introduces you and your books
News when a new book or deal goes live
Behind-the-scenes notes, character art, or reading lists
Recommendations of other authors in your genre
Aim for steady, friendly emails. Once or twice a month works for many authors.
ARCs are free early copies you send to readers before or around launch. They help a new book collect honest reviews, which give future buyers confidence.
KDP's help page on customer reviews is clear: "You may provide free or discounted copies of your books to readers, as long as you do not require a review in exchange or attempt to influence the review." It adds that "Offering anything other than a free or discounted copy of the book, including gift cards, will invalidate a review."
The US Federal Trade Commission also finalized a rule in August 2024 that bans fake reviews, buying reviews that must say something positive or negative, and undisclosed reviews by insiders.
In practice, that means:
Give the book freely. Never require a review.
Never ask for a positive review or a certain star rating.
Never offer gift cards, cash, or other rewards for reviews.
Never buy reviews or swap reviews with other authors.
Ask reviewers to say they received a free copy, for example: "I received a free copy of this book and am leaving a voluntary review."
Your email list (your warmest readers)
Reader groups and book clubs in your genre
Book bloggers and Bookstagram or BookTok creators who review your genre
Send ARCs four to six weeks before launch so readers have time to finish.
Temporary discounts can bring a wave of new readers, especially to the first book in a series.
If your ebook is enrolled in KDP Select, you can run either up to five free promotion days or a Kindle Countdown Deal in each 90-day term. A Countdown Deal shows a timed discount and lets you keep the 70% royalty option even when the sale price drops below $2.99.
BookBub sends daily deal emails to large lists of readers sorted by genre. A Featured Deal is the most sought-after slot. BookBub's own requirements say your book must be:
Free or discounted by at least 50%
The lowest price offered in the last 30 days
Free of errors and well formatted
Full length (at least 150 pages for novels and 100 for nonfiction)
Not featured in the last 6 months, and the author not featured in the last 30 days
BookBub Insights says about 25% of submissions are chosen, while BookBub's US submission help page says it can select only about 10 to 15% of the books submitted for US Featured Deals. Prices depend on genre, deal price, and region. One 2026 summary of BookBub's published pricing listed $0.99 deals at $586 in Fantasy and $948 in Thrillers, but these prices change, so check BookBub's pricing page before you apply.
Frequent sales can teach readers to wait for the next deal. Space out your promotions, and focus them on books that lead into a series.
Paid ads can work, but they can also burn money quickly. The main options for authors include Amazon Ads, BookBub Ads, and ads on Facebook and Instagram.
Simple rules for testing ads:
Start with a small daily budget.
Test one change at a time: image, headline, or audience.
Track cost per sale, not just clicks.
Remember read-through. If book one leads readers to books two and three, a small loss on book one can still make sense.
Ads tend to work better for series and for genres with heavy readers, such as romance, mystery, and thrillers. A single standalone book is harder to advertise at a profit.
Social media can introduce your book to readers who never browse store charts. Publishers Weekly, reporting on Circana BookScan data, noted that adult fiction has been the strongest print segment since the pandemic, helped by the emergence of BookTok.
Tips that help on BookTok and Bookstagram:
Show the mood and tropes, not just the cover. Readers search for feelings like "enemies to lovers" or "small-town mystery."
Post regularly. Short, simple videos are fine.
Talk with readers in the comments.
Share other authors' books too. Generous accounts tend to grow.
If you pay or gift a creator, they should disclose it clearly, as the FTC's Endorsement Guides require.
You do not need to be on every platform. Pick one you enjoy and can keep up with.
A newsletter swap is when two authors in the same genre mention each other's books in their emails. It costs nothing and reaches readers who already like similar stories. Partner with authors whose books truly match yours, and only share books you would honestly recommend.
A simple plan keeps you on track:
8 to 12 weeks before launch: finalize the cover and description, set up your pre-order, and invite ARC readers.
4 to 6 weeks before: send ARCs, schedule newsletter swaps, and line up deal sites if you plan a launch discount.
Launch week: email your list, post on social media, and thank early reviewers.
After launch: test small ads, apply for promotions, and start writing the next book.
Most self-published authors build income slowly. Written Word Media's 2025 survey results page reports that 44% of authors earn $100 or less a month, while 56% earn more than $100, 13% earn more than $5,000, and 8% earn more than $10,000. A Written Word Media survey covered by the Alliance of Independent Authors found that authors in the highest income bracket, over $20,000 a month, had published an average of 61 books. The pattern is clear: more books, steady marketing, and patience tend to go together.
There is no fixed amount. Many authors start with free tactics like an email list, ARCs, and newsletter swaps, then test small ad budgets. Only spend what you can afford to lose while you learn.
Yes. KDP allows free or discounted copies as long as you do not require a review or try to influence it. Offering gift cards or other rewards will invalidate reviews.
It can bring a large wave of readers, especially for the first book in a series. It is also selective, with as few as 10 to 15% of US submissions chosen by BookBub's own count, and it costs hundreds of dollars or more, so the math works better with a series.
Start building your email list and social presence while you write. Begin active launch work about two to three months before release.
