Talk to usStart by deciding whether you need private feedback, an editorial assessment, or voluntary customer reviews. Those outcomes require different processes. A useful reader can tell you what is confusing or missing even if they never post publicly.
This guide compares published service mechanics checked September 26, 2026. It is a source-based comparison, not a hands-on service test, certification, or guarantee of Amazon acceptance. Adigy makes advertising software; the provider links below are ordinary links without affiliate tracking.

What kind of feedback would help your book?
- Private beta-reader feedback: use it to improve clarity, structure, usefulness, or the reading experience before or after publication.
- Advance reader copies: share a suitable edition with interested readers. A copy should not create an obligation to publish a review.
- Editorial reviews and endorsements: obtain a professional or expert assessment and use authorized quotations with accurate attribution. See the editorial-review guide.
- Amazon customer reviews: readers submit their own opinions through Amazon, subject to its rules and moderation.
A launch does not need a predetermined review count to begin. Build a book and listing that make the value clear, then seek readers whose interests genuinely match it. A gardening beginner may provide more useful feedback on an introductory rose-growing guide than a reader recruited solely because they can post quickly.
Amazon’s rules apply independently of a service’s claims
KDP’s customer-review guidance permits free or discounted book copies without a review requirement or an attempt to influence the review. It says additional compensation, including gift cards, invalidates reviews. Reviews exchanged for compensation can be removed.
Our practical conclusion is to examine what a reader receives and what action earns it. Calling an opinion “honest” does not answer whether it was incentivized. Nor does preventing direct A-reviews-B/B-reviews-A exchanges establish that every other incentive is acceptable.
Paid private reading and an Amazon customer review are separate activities. Do not make payment, credits, promotion access, refunds, or future work depend on posting a customer review. Amazon decides what it accepts; a service cannot guarantee that decision on its behalf.
A voluntary reader-feedback workflow
- Define the reader. Describe the genre, level, topic, format, and likely time commitment honestly.
- Invite interest. Use your own reader list or a community that permits such invitations. Offer a copy without requiring a public review.
- Ask useful private questions. What did the reader expect? Where did they get stuck? Which section would they recommend improving?
- Keep opinions independent. Do not supply review text, required stars, or instructions to hide a relationship.
- Make a public-review request optional. Do not send it only to readers who gave positive private feedback or make continued access depend on responding.
- Record improvements. Group repeated issues, decide what to change, and keep a version history.
Example wording for a voluntarily supplied book copy: “Thank you for reading. If you choose to share a review, please give your own honest opinion. A review is optional, and there is no reward for posting one. Private feedback is also welcome.”
This wording does not fix an otherwise incentivized arrangement. The actual process, including any third-party rewards, matters more than the invitation’s phrasing.
Book Bounty, BookVillage, and BookReverb: what differs?
The services below were requested for comparison. Their descriptions and terms do not constitute independent confirmation of compliance. We have not verified what every account sees after sign-in; confirm the exact assignment and billing terms before joining.
Book Bounty: review-linked points
Its July 2026 terms describe readers posting Amazon reviews to earn Bounty Points, which publishers can use for their own books. Participation is described as optional; direct reciprocal reviewing is prohibited, and review verification may require Amazon’s confirmation email. The terms exclude guarantees about count, timing, permanence, or sales.
The same terms offer an eligible-plan refund request within 30 paid days, excluding Publisher Pro, and no prorated refunds. Check the plan-specific checkout before subscribing. The relationship between public reviews and points is the key issue to evaluate against Amazon’s rules, even when points do not depend on positive sentiment.
BookVillage: assignments and future promotions
The official workflow says readers reserve assignments, read and review during a defined window, and unlock future promotions through completed assignments. Its terms describe voluntary participation, prohibit delegated or fabricated reviews, and do not guarantee review counts or visibility. They describe subscription cancellation under checkout terms and possible refund denial for abuse.
Clarify whether a public review is necessary to retain or earn promotion access. A review-linked benefit deserves scrutiny even if no cash changes hands. The workflow’s timing claims are the provider’s claims; we have not verified that a particular posting schedule protects an Amazon account.
BookReverb: funded reading and feedback assignments
Its June 2026 terms describe funded reader assignments and completion verification that may include private feedback, reports, or surveys. Funds may cover reader compensation and platform fees. Public reviews are not guaranteed, and the terms explicitly disclaim Amazon approval or guaranteed compliance. Payments and credits are generally non-refundable except where law or written terms require otherwise.
Before funding an assignment, confirm the completion steps and whether readers can receive full compensation without any public review. Treat it as a reading/feedback purchase only if that is the actual arrangement. Do not turn paid feedback into a requirement to post on Amazon.
Questions to ask before paying
Ask for a concrete example of the reader’s assignment screen and the author’s order terms. A broad assurance is less useful than knowing which exact actions unlock the promised benefit.
- What is the deliverable: exposure, a completed read, private feedback, or a public review?
- Can a reader decline a public review while keeping all payment, points, eligibility, and access?
- Does reviewing unlock promotion of the reader’s own book, directly or indirectly?
- What happens if the reader dislikes the book, never finishes, or posts nothing?
- What is charged upfront, what renews, and what happens to unused funds or credits?
- Does a removed review create a refund, credit, replacement, or no remedy? Get the applicable terms.
- What files and personal data are collected, and who can access them?
Compare the full expense, including subscription, book copies, reader budgets, and your own time. We have not established comparable current checkout prices across these services, so we do not rank them by cheapest cost per review. A public review is not a guaranteed purchased unit.
Use the feedback to improve the reader’s experience
Keep a simple log: reader type, edition, specific issue, number of independent mentions, proposed change, and completion date. Distinguish an individual preference from a repeated mismatch between the promise and the contents.
If readers repeatedly expected more advanced material, fix the positioning or the book before buying more traffic. If they found the instructions hard to follow, improve the examples or structure. Use the detail-page guide to make the revised promise visible, then the launch framework to plan the next bounded advertising test.
Do not pressure a customer to change criticism after an update. Explain improvements accurately and let readers form their own opinions. Useful feedback should improve the product even when it produces no new public review.
