Free Book Promotion Sites for Authors in 2026: 15 Options Worth Your Time

You just published a book, your budget for marketing is close to zero, and every "book promotion" search result wants $50 to $200 for a featured spot. Free book promotion sites for authors do exist, they're just harder to find than the paid ones, because nobody is paying to advertise them to you. This list covers the sites that genuinely have a no-cost tier, what they actually require in return, and which ones are worth your submission versus which ones waste an afternoon.

A free book promotion site is a platform, newsletter, or community that features your book to its existing readership at no charge, usually in exchange for the book being free or discounted during the promotion window. The strongest options reach tens of thousands of readers with zero cash outlay. The weak ones ask for your email list, your time filling out forms, and deliver almost no downloads in return.

At Skriuwer, we spend our days recommending books to readers, which means we also watch which discovery channels actually move a title and which ones are noise. This list reflects that side of the equation: what gets a book in front of real readers who buy or download it, not what has the biggest submission form.

Best truly free book promotion sites

These sites let you submit at no cost, no credit card, no upsell required to get listed at all. Paid tiers usually exist alongside the free one for more visibility, but the free tier is real, not a bait-and-switch.

1. Online Book Club

Online Book Club runs a free listing option alongside its paid review service. The free submission gets your book added to their catalog, which readers browse by genre, and occasionally features titles in their newsletter. It works best for fiction and nonfiction with broad reader appeal rather than niche nonfiction.

2. Digital Book Today

Digital Book Today accepts free submissions for books priced at $0.99 to $2.99, featuring them in genre-specific lists that go out to their reader base. Turnaround can take a few weeks since the free tier queues behind paid listings, so submit at least three weeks before your promotion date.

3. OHFB (One Hundred Free Books)

OHFB has a limited free submission window each month for books that are free on Amazon. It's competitive because everyone wants the free slot, but landing one puts your book in front of an engaged list of free-book hunters. Submit your best-reviewed title, since OHFB screens for rating quality even on the free tier.

4. Reading Deals

Reading Deals runs free listings for free and discounted ebooks across genres. The audience is smaller than the big-name paid sites, but the barrier to entry is also lower, and it's a reasonable stacking option alongside two or three other free listings in the same week.

5. Fkbooksandtips (Free Kindle Books and Tips)

This site's free tier is limited and slower to secure than its paid slots, but it maintains a genuinely large Kindle-reading subscriber base. Worth the submission for free promotions specifically, since that's where the free tier applies.

Free (or mostly free) social and community channels

These aren't submission-based promo sites in the traditional sense, but they cost nothing beyond your time and consistently outperform low-tier paid promo sites for engaged reach.

6. Goodreads Author Program

Goodreads lets you claim an author profile, run giveaways, and post updates to followers for free. Giveaways in particular generate real visibility: every entrant sees your book cover and blurb, and many add it to their "want to read" shelf even without winning. This is one of the highest-leverage free tools available to any author.

7. Reddit genre communities

Subreddits like r/booksuggestions, r/selfpublish, and genre-specific communities (r/Fantasy, r/RomanceBooks) allow author participation under their specific self-promotion rules. Read the rules for each subreddit before posting; most require a ratio of genuine participation to promotional posts, and violating that gets you banned. Done correctly, a well-received post in a large genre subreddit can outperform a $100 paid promo site.

8. BookTok and Bookstagram

TikTok and Instagram cost nothing to post on, and the book community on both platforms (BookTok specifically) has driven measurable backlist sales spikes for both indie and traditionally published authors. The catch is that it takes consistent posting over months, not a single post, to build traction. Treat it as a long game, not a promotion tactic for a single launch week.

9. Facebook reader groups

Genre-specific Facebook groups (thriller readers, romance readers, sci-fi readers) often allow scheduled "self-promo days." Join several relevant to your genre, read each group's posting rules, and participate genuinely between promotional posts. Group admins ban authors who only show up to sell.

Free tools that support a promotion, not just list your book

10. Reader magnet delivery tools

Several free-tier tools exist purely to deliver a reader magnet (a short story, sample chapters, a bonus epilogue) to new subscribers, which supports a promotion rather than generating traffic on its own. Pair whichever one you use with a newsletter swap (see below) to actually drive readers to the free download.

11. Author group promotions

A handful of platforms let authors pool audiences for free by building shared reader magnet landing pages and running group promos together. The value is entirely in the pooling: you get exposure to other authors' mailing lists in exchange for offering the same to yours.

12. Author newsletter swaps

Not a "site" in the traditional sense, but newsletter swaps, where two authors feature each other's book to their existing subscriber lists, cost nothing and often convert better than cold promo sites because the recommendation comes from a trusted source. Facebook groups like "Newsletter Swap for Authors" exist specifically to arrange these.

13. Written Word Media free newsletter

Written Word Media (which owns several paid promo sites) publishes a free newsletter with marketing advice and occasionally features reader deals. It's not a guaranteed listing, but subscribing keeps you aware of free promotional opportunities they run periodically.

14. Library Thing Early Reviewers

Library Thing's Early Reviewers program is free to list a book in, and it reaches a reader base that leaves reviews reliably, which compounds into future discoverability on Amazon and Goodreads. Reviews from this program tend to be more thoughtful than average, since the readers self-select for genuine interest.

15. Your own back catalog

If you have more than one book published, cross-promoting your own titles in the back matter, on your website, and through a free "also by this author" page costs nothing and is the single most overlooked free promotion channel. Readers who finish one book and immediately see what else you've written convert at a far higher rate than any external promo site.

How to pick which free sites are worth your time

With over a dozen options and limited hours, submitting to everything is a mistake. Filter by three questions:

• Does the audience match your genre? A free listing on a site whose readers want cozy mysteries won't move a hard sci-fi title, regardless of subscriber count.
• What does the free tier actually include? Some "free" sites bury the real free option under three clicks of upsells. If a listing takes more than 10 minutes to submit, check whether the free tier is worth that time first.
• Do they require a minimum rating or review count? Several sites on this list (OHFB, Fussy Librarian's free-adjacent tier) screen submissions by star rating. Don't waste a submission slot on a book that won't clear their bar; build reviews first.

Frequently asked questions

Are free book promotion sites actually effective?

Yes, when matched to genre and stacked together. A single free listing rarely moves the needle alone, but combining three or four free sites plus a Goodreads giveaway and a newsletter swap in the same week produces a visible sales or download bump for most genres.

How many free book promotion sites should I submit to at once?

Three to five in the same week is the sweet spot. Fewer than that limits your reach; more than that spreads your launch window too thin and makes it hard to tell which channel actually worked.

Do free book promotion sites require my book to be free or discounted?

Most do. Sites built for free-book hunters (OHFB, Reading Deals) require the book to be $0. Others accept discounted books at $0.99 to $2.99. Check each site's requirement before submitting; a mismatched price gets your submission rejected outright.

Can I use free book promotion sites for a first-time launch?

Yes, but pair them with reviews first if possible. Sites that screen by star rating will reject a brand-new book with zero reviews, so a small ARC or beta-reader push before launch widens which free sites will accept you.

What's the difference between free book promotion sites and paid ones?

Paid sites (BookBub Featured Deals being the top tier) guarantee placement and typically reach a larger, more curated list, which is why they charge. Free sites either have smaller reach, slower turnaround, or more competition for limited free slots, but cost nothing to try.

Do book promotion sites work for nonfiction?

Many are fiction-heavy, but Online Book Club, Digital Book Today, and genre-specific Reddit and Facebook communities all accept nonfiction. Search each site's genre categories before assuming it's fiction-only.

How far in advance should I submit to a free book promotion site?

Two to three weeks minimum. Free tiers queue behind paid submissions on most sites, and some (like OHFB) only open free slots on specific days each month.

Keep your promotion budget for what works

Free book promotion sites won't replace a strong Amazon algorithm push or a well-timed BookBub Featured Deal, but they're not meant to. Used correctly, in a genre-matched stack, they fill the gap between "no budget" and "first paid promo," and several (Goodreads giveaways, newsletter swaps, your own back catalog) belong in every author's toolkit regardless of budget.
