The Best Book Promotion Sites for a Launch, Ranked

Editor's pick

BookBub is not simply the largest book promotion site — it is, by a margin David Gaughran has described as making all other discount promotion sites together not match half its power, the only channel where authors consistently report achieving direct positive ROI on a single placement. The mechanics are well-documented. BookBub serves more than 15 million subscribers across 42 genre categories and reports an official average 196 times increase in earnings during the deal window. Seventy percent of authors report increased sales of other books after a Featured Deal, and 70 percent or more of total profitable return comes from backlist series sell-through rather than royalties on the featured title itself. Cost is set per genre and price point: a Fantasy $0.99 deal runs $586; Historical Fiction at $0.99 runs $1,109; the full range spans $113 (Children's free) to $4,216 (Historical Fiction at $3+). Acceptance is the constraint: US submissions are accepted at 10 to 20 percent overall, with US-only deals estimated below 5 percent by practitioner sources. Most authors are rejected 5 to 20 times before their first acceptance — that is the median path, not an outlier. Eligibility requires a 50 percent or deeper discount from the recent retail price, at least 15 to 25 reviews at a 4.0 average (50 or more in Romance and Thriller), and wide distribution across retailers is a meaningful competitive advantage in the selection process. Dave Dobson's documented 2024 free deal: $712 cost, 20,000 downloads on Day 1, 30,000 over five days, Amazon ratings growing from 35 to 334.

Freebooksy is the largest free-book-specific promotion newsletter in indie publishing, with 1,345,000 registered readers who have self-selected for one kind of discovery: free ebooks they have not yet read. That targeting precision is its primary asset. Genre-level download benchmarks documented by Kboards authors and the Freebooksy for Authors page average approximately 5,000 downloads on Day 1 for Thriller, 3,500 for Mystery, and up to 7,200 in a single day in high-performing testimonials. Standard feature pricing runs $75 to $120 for most fiction genres effective February 2025 — Cozy Mystery $90, Mystery $100, Thriller $100, Steamy Contemporary Romance $120 — and the Limelight Dedicated E-Blast (a standalone single-title email to 281,000 subscribers) costs $550 for authors who want more concentrated placement. The 2024 Written Word Media reader survey gave Freebooksy a reader recommendation score of 8.87 out of 10, confirming the audience trusts the curation. Author-side ROI is genre-dependent: a 2020 Written Word Media study of 61 promotions found Romance series promos produced a positive ROI in 89 percent of cases, and Fantasy/Paranormal in 83 percent. Two operational rules carry more weight than any other detail. First: the book must remain free until 11:59 PM PST on the promotion day — Freebooksy's support documentation explicitly states that changing the price mid-day is a permanent ban offense with no refund. Second: the same title can only be promoted once every 30 days minimum; author community reports document roughly a 66 percent decline in downloads on repeat runs as audience overlap grows.

Bargain Booksy occupies the Written Word Media slot that Freebooksy cannot fill: discounted but paid ebooks at $0.99 to $5.00. Its 317,000 registered users constitute a smaller audience than Freebooksy's, but these readers are in a purchasing mindset, not just browsing for free downloads. The 2024 Written Word Media reader survey gave Bargain Booksy a reader recommendation score of 8.50 out of 10, confirming that its subscribers trust the curation. Genre-specific placement pricing runs $35 to $200, placing individual placements well below BookBub's entry cost and making it the most accessible paid-book promotional option for most authors. The corpus data is unambiguous about price-point optimization: Bargain Booksy performs at $0.99 and $1.99 and fails measurably at $2.99 or above. Multiple authors reported zero or negligible results at $2.99 in 2024 community reporting. One author documented hitting Amazon rank 2,261 overall and entering the top 100 in three genre categories within 54 hours at a $1.99 price. The best-case documented result on a solo promotion is 273 paid units. Bargain Booksy has one structural advantage over Freebooksy: it accepts pre-orders, making it available for launch-week campaigns before a book is fully published. Approximately 68.4 percent of all Bargain Booksy promotions in 2023 came from KDP Select or Kindle Unlimited-enrolled books, confirming full compatibility with both KU-exclusive and wide authors. The 2024 Written Word Media indie author survey rated Freebooksy and Bargain Booksy combined at 3.3 out of 5 for author satisfaction — useful context about the gap between reader enthusiasm and author ROI.

Pricing

$35–$200 per placement depending on genre (as of 2025–2026); no subscription required

Ereader News Today is the most cost-efficient mid-tier promotional site when measured by cost-per-download, reaching a combined audience of 475,000 Facebook fans and 200,000 email subscribers for $20 to $35 per placement. The $20 tier applies to Science Fiction, Fantasy, Horror, and Dystopian; the $35 tier covers Romance, Thriller, Mystery, and Nonfiction — pricing that makes ENT accessible even for authors with modest promotional budgets. In a documented seven-site stacked free-book promotion published on the Goodreads Authors Forum, ENT generated 1,216 downloads on its promotion day, placing it in the mid-tier range alongside Fussy Librarian (1,568) and behind Robin Reads (1,894) and Freebooksy (3,449). Cost-per-download across that comparison ran approximately $0.04, matching Robin Reads' efficiency. David Gaughran's practitioner assessment rates ENT's expected result for a $0.99 promotion at approximately 10 to 20 paid sales — directionally accurate for paid books, since ENT's audience skews toward free-download behaviors and conversion on paid is lower. Operational constraints are meaningful: a 90-day gap is required between promotions of the same title, limiting ENT to roughly four uses per year per book, and the book's discounted price must be live and confirmed by 6:00 AM EST on the promotion day — Kindle Countdown Deals qualify as long as they are active by that deadline. ENT functions best as a supporting site in a stack, placed the day before or after the BookBub anchor, adding download velocity without duplicating the audiences reached by Freebooksy or Robin Reads on adjacent days.

Best for

Budget-conscious authors building a promo stack to support a BookBub anchor deal

Pricing

$20 (Sci-Fi/Fantasy/Horror/Dystopian) or $35 (Romance/Thriller/Mystery/Nonfiction) per placement (as of 2025–2026)

Robin Reads consistently outperforms its list size in per-placement download volume. Its 194,000-member audience is the smallest in this ranking, but in a documented seven-site stacked free-book promotion published on the Goodreads Authors Forum, Robin Reads generated 1,894 downloads — the highest of any mid-tier site in that comparison, above ENT's 1,216, above Fussy Librarian's 1,568, and second only to Freebooksy's 3,449 in the same seven-day stack. Cost-per-download runs approximately $0.04, identical to ENT's efficiency at a higher absolute volume. Pricing runs $60 to $85 depending on genre per David Gaughran's tested benchmarks — more expensive than ENT but justified by the volume differential in head-to-head comparisons. Robin Reads accepts free books and $0.99 books only; it is not a viable channel for promotions above that price point. The 90-day gap between same-title promotions is the same hard constraint as ENT, limiting placement frequency. In a well-designed stack, Robin Reads works best positioned one to two days before the BookBub anchor — it generates a warmup wave of downloads that begins to signal velocity to Amazon before the larger Featured Deal email arrives. Its smaller but evidently more engaged list likely explains the stronger download-per-subscriber ratio versus larger but less targeted newsletter properties. Nicholas Erik rates Robin Reads among the more reliable non-BookBub promo sites for fiction genres. For authors without the budget for BookBub, a Robin Reads and Freebooksy combination on consecutive days represents the highest-performing non-BookBub free-book stack available.

Free-book promo stacks positioned one to two days before a BookBub anchor, or as the top mid-tier site in a non-BookBub stack

Pricing

$60–$85 per placement depending on genre (as of 2025–2026, per David Gaughran's benchmarks)
