Introduction
The first time I launched a book without any reviews, I watched it sink without trace. Not because the writing was poor — but because a page with zero reviews is invisible. Readers scroll past. The algorithm ignores it. You might as well have published into a void.
That experience is what pushed me to take ARC campaigns seriously, and it's one of the things I cover in Google. Panic. Repeat. — the uncomfortable truth that a book launch is a marketing event first and a publishing event second. Reviews are not a nice-to-have; they are the social proof that converts browsers into buyers, and they need to exist from day one.
The good news is that a well-run ARC campaign is not complicated. It does not require a large budget or a massive existing audience. What it requires is the right timing, the right platforms, and a clear understanding of what Amazon's rules actually permit — which is considerably more than most authors assume.
This guide covers all of it, with UK-specific pricing and platform context throughout.
TL;DR — Key Takeaways
- ARC readers can legally post Amazon reviews for free copies, provided they disclose the arrangement and were not paid for a positive review.
- Start your ARC campaign 6–8 weeks before launch; reviews posted in the first week carry the most algorithmic weight.
- BookSirens suits most fiction genres; BookSprout performs better for romance and nonfiction — pricing and tiers differ significantly.
- Your own email list will almost always outperform cold platform traffic for review conversion rates.
- Send a clean, properly formatted EPUB or PDF — a poorly formatted ARC file is one of the most common reasons readers quietly abandon a book before reviewing.
- Aim for 40–60 ARC sign-ups to land 15–25 posted reviews; stagger outreach so reviews do not cluster on a single day.
What ARC Readers Are and Why They Matter
An advance review copy (ARC) reader receives a pre-publication version of your book in exchange for an honest review. The arrangement is standard practice across both traditional and self-publishing, and when executed properly it means your book accumulates genuine reviews before — or immediately after — it goes live on Amazon. A new title with fifteen to twenty-five reviews on launch day is treated very differently by both the algorithm and by readers than one with none.
The mechanics are simple: you distribute digital copies (typically EPUB or PDF) to readers who have agreed to post a review by your launch date. No payment changes hands. No positive review is guaranteed or required. The reader discloses they received a free copy, and that disclosure is sufficient under Amazon's current policy. What makes ARC campaigns genuinely effective is the combination of social proof at launch — when algorithmic momentum is most achievable — and the credibility signal that a body of reviews provides to readers who discover the book weeks or months later. A book with twenty honest reviews from launch day continues to benefit from that foundation long after the campaign itself is over. For a detailed look at how reviews feed into broader launch strategy, see the book launch strategy guide.
Amazon's Review Rules — What They Actually Say
Amazon permits reviewers to post honest reviews for books they received free of charge, provided the reviewer discloses the arrangement and was not compensated specifically for a positive review. This is the current policy as of May 2026, and it is considerably more permissive than the community memory of past crackdowns suggests.
The key distinction Amazon draws is between incentivised reviews — where payment or reward is tied to a positive outcome — and editorial reviews, where a free copy is exchanged for an honest opinion. ARC campaigns fall firmly in the second category. The disclosure does not need to be formal or lengthy. A single line such as "I received an advance review copy of this book" satisfies the requirement. What Amazon does suppress is reviews from accounts with no purchase or review history, and reviews that appear in suspicious clusters — for example, twenty reviews posted on the same day from accounts that have never reviewed anything else. Stagger your outreach and recruit readers with established Amazon accounts wherever possible. Reviewers with a history of posting on Amazon are far less likely to have their reviews removed, regardless of whether the copy was free.
Choosing the Right ARC Platform
BookSirens
BookSirens hosts over 12,000 authors and 51,000 reviewers as of May 2026. Its Promote Plan costs $10 per book plus $2 per download, making it one of the more cost-transparent options available. The reader pool skews towards committed reviewers, and the platform's tracking interface makes it straightforward to monitor who has downloaded and who has posted. BookSirens performs best for fantasy, science fiction, thriller, literary fiction, and YA. Conversion rates of 30–50% are realistic when the cover and blurb are strong. If either is weak, expect lower numbers — the platform surfaces your book to readers who make the same snap judgements as paying customers. An annual author plan is also available for authors running multiple campaigns across the year.
BookSprout
BookSprout offers a free tier supporting up to 20 ARC copies, which makes it accessible for authors testing the format for the first time. Paid plans run from $90 per year (Growing Author) through $190 per year (Pro Author) to $229 per year (Bestselling Author). The platform has a larger raw user base than BookSirens but a lower average engagement rate. It performs better for romance — particularly steamy subgenres — Christian fiction, and nonfiction. For authors in those categories, the free tier alone may be sufficient for a first campaign.
NetGalley
NetGalley is the premium option, with direct listings costing $499–$575 for a six-month window. Co-op routes reduce this significantly: the Independent Book Publishers Association (IBPA) offers access for approximately $199 for three months, and Victory Editing offers a co-op route at $575 per year. NetGalley carries credibility with librarians, trade reviewers, and bookstagram influencers that the other platforms do not replicate. It is worth the cost if you are targeting library placement or trade coverage alongside Amazon reviews, but it is not the right starting point for most self-published authors on a tight budget.
StoryOrigin
StoryOrigin combines ARC distribution with newsletter swap and reader magnet tools, making it useful for authors who want to build their list and generate reviews simultaneously. A free tier exists with limited functionality. Paid plans run from $10 per month (Basic) to $20 per month (Premium), with an annual option at approximately $100 per year — a 50% discount applies for additional pen names on the annual plan.
BookFunnel
BookFunnel handles ARC delivery rather than reader recruitment, but it is worth including here because it integrates cleanly with your own list. There is no free tier; plans start at $20 per year (Mini) and scale up through Mid-list and above at approximately $250 per year. If you are managing your own ARC list rather than relying on a platform's reader pool, BookFunnel is one of the cleanest ways to deliver files and track downloads.
How to Build Your Own ARC Reader List
Building your own ARC reader list will almost always outperform cold platform traffic for review conversion rates, because your own readers already trust you and are more likely to finish the book and post. The trade-off is that it requires an existing audience — even a small one — and some lead time.
Start collecting ARC sign-ups at least 60 days before your launch date. A simple landing page or a Google Form linked from your newsletter is sufficient. The ask should be specific and honest: explain what you are offering (a free early copy), what you are asking in return (an honest review on Amazon and/or Goodreads before launch day), and what the commitment involves (finishing the book and posting within the timeframe). Avoid vague language like "support my launch" — it makes the arrangement feel transactional without being clear about what the transaction is.
Post the sign-up link in your author newsletter, any Facebook reader group you run, genre-specific Facebook groups (check posting rules first), and relevant Reddit communities for your genre. If you have any presence on BookTok or bookstagram, a short video or post explaining the ARC opportunity can generate sign-ups quickly. For a full guide to building the email list that makes this possible, see how to build an author email list from scratch.
Aim for 40–60 sign-ups to land 15–25 posted reviews. Some readers will not finish; some will finish but not post. That drop-off is normal and not a reflection of your book.
Running the Campaign — Step by Step
Step 1 — Prepare your book before recruiting anyone
ARC readers judge covers and blurbs exactly as paying customers do. A weak cover or a blurb that summarises rather than hooks will reduce both your sign-up rate and your review rate. Before you post anywhere, confirm you have a professional cover that fits genre conventions, a blurb that ends with a hook, and a clean formatted ARC file. Do not send readers a Word document. It signals the book is not ready, and it makes reading uncomfortable on most devices. A properly formatted EPUB is the standard; PDF is an acceptable fallback. For guidance on getting your file into the right shape, the KDP formatting checklist is a useful starting point.
Step 2 — Choose your platform or list strategy
Use the platform comparison above to identify the best fit for your genre. If you have a newsletter list of more than 500 subscribers, prioritise your own readers and use platforms to supplement. If you have fewer than 500 subscribers, platforms are the more reliable route to sufficient volume. You can run both simultaneously — there is no conflict between recruiting from your own list and listing on BookSirens or BookSprout at the same time.
Step 3 — Send the ARC with a clear brief
When you send the file, include a short email covering: the launch date, where you would most like the review posted (Amazon UK, Amazon US, Goodreads — pick your priority), the one-line disclosure readers can paste ("I received an advance review copy of this book"), and a reminder that honest reviews are more useful than positive ones. Keep the email under 200 words. Do not guilt-trip. Do not over-explain.
Step 4 — Follow up once
Send one reminder email seven to ten days before launch. Keep it brief — a single paragraph noting the launch date, linking to the review page, and thanking them for their time regardless of whether they post. One follow-up is appropriate. More than one damages the relationship and reduces the likelihood of that reader signing up for future campaigns.
Step 5 — Stagger your outreach
Do not send all ARC copies on the same day, and do not ask all readers to post on the same day. Reviews that cluster on a single date from accounts with no prior history are a pattern Amazon's systems flag. Spread your outreach over two to three weeks and let posting happen organically across the launch window.
UK-Specific Considerations
UK authors face a specific challenge with ARC campaigns: Amazon.co.uk and Amazon.com are separate marketplaces with separate review counts. A review posted on Amazon US does not appear on the UK product page, and vice versa. This matters because most UK readers will check the Amazon.co.uk listing, and if your reviews are concentrated on the US store, your UK page can look sparse even after a successful campaign.
When recruiting ARC readers, be explicit about which store you want them to post on. If you have a UK audience, prioritise Amazon.co.uk. If you are targeting both markets, recruit readers in both regions and direct each to the appropriate store. UK-based ARC readers are easier to find through genre Facebook groups and UK bookstagram communities than through US-centric platforms, where the reader pool skews American.
For authors planning to sell through UK bookshops as well as Amazon, note that trade reviewers and librarians — the audience NetGalley reaches most effectively — operate on different timelines. Physical retail requires a longer lead time than digital, and your ARC campaign should be planned accordingly. If UK bookshop distribution is part of your strategy, the guide to getting your book into UK bookshops covers the distributor relationships and ISBN requirements that underpin that route.
UK authors also need to be aware that printed books are zero-rated for VAT in the UK, while ebooks sold via Amazon UK are subject to standard-rate VAT, handled by Amazon. This does not directly affect ARC campaigns — you are distributing digital files, not selling — but it is relevant context for your broader pricing strategy once the book is live. For the full picture on UK self-publishing tax obligations, see the self-publishing tax guide for UK authors.
Common Mistakes and How to Avoid Them
Mistake 1 — Starting the campaign too late
Recruiting ARC readers two weeks before launch means most will not finish in time. Reviews that land in the first week of launch carry the most algorithmic weight on Amazon.
How to avoid: Begin your ARC campaign 6–8 weeks before your launch date. Send files no later than five weeks out, and set a review deadline of one week before launch day.
Mistake 2 — Sending a poorly formatted file
A badly formatted EPUB — broken chapter headings, inconsistent spacing, missing front matter — signals an unfinished book. Readers who encounter formatting problems are less likely to finish and far less likely to review.
How to avoid: Run your manuscript through a proper formatter before sending a single ARC copy. The guide to formatting an ebook for Kindle covers the key requirements. If you want a second opinion on your file before it goes out, the KDP readiness audit will catch the most common issues.
Mistake 3 — Recruiting from platforms with the wrong genre fit
Using BookSirens for a nonfiction title, or BookSprout for literary fiction, will produce lower conversion rates than the platform average — not because the platforms are poor, but because the reader pools do not match.
How to avoid: Research each platform's genre strengths before committing. Check the platform's own genre categories and, where possible, look at community feedback from authors in your specific genre.
Mistake 4 — Asking for positive reviews rather than honest ones
Explicitly or implicitly signalling that you want positive reviews makes readers uncomfortable and, if the language is strong enough, puts you in breach of Amazon's review policy.
How to avoid: Use the word "honest" consistently in all communications. Frame the ask as helping readers find a book that is right for them, not as generating marketing material for you.
Mistake 5 — Sending too many follow-up emails
Multiple follow-up emails after the initial send feel like pressure. They damage the relationship with readers who intended to review but ran out of time, and they reduce the likelihood of those readers signing up for future campaigns.
How to avoid: One follow-up email, sent seven to ten days before launch. That is the limit.
Mistake 6 — Ignoring the Amazon UK vs Amazon US distinction
Concentrating all your ARC outreach on US-based readers means your Amazon.co.uk page may have few or no reviews at launch, even if your US page looks healthy.
How to avoid: Segment your ARC list by region where possible, and direct UK readers explicitly to Amazon.co.uk. Recruit from UK-based communities as well as US-centric platforms.
Mistake 7 — Recruiting readers with no review history
Reviews from brand-new Amazon accounts or accounts with no prior review activity are more likely to be suppressed by Amazon's systems, regardless of whether they are genuine.
How to avoid: When recruiting from your own list or from communities, mention that the campaign is most useful for readers who already review books on Amazon. You cannot guarantee account history on platform readers, but you can filter for it on your own outreach.
Mistake 8 — Treating platform conversion rates as a measure of book quality
A 30% conversion rate on BookSirens is not a sign that readers disliked your book. It is a normal rate for a cold audience. Authors who interpret low conversion as rejection often abandon ARC campaigns prematurely.
How to avoid: Set realistic expectations before you launch the campaign. A 30–50% conversion rate on a platform is a good result. Focus on the absolute number of reviews, not the percentage.

Expert Tips from 25 Years in the Industry
Your file is your first impression. I have seen authors spend months writing a book and then send ARC readers a document that looks like a draft. The reader's experience of your ARC file shapes their review — not just what they say, but whether they bother to say anything at all. A clean, professionally formatted EPUB takes a few hours to produce properly and pays for itself many times over in review conversion.
Small lists outperform large platforms when the relationship is real. I have run campaigns where a list of 200 engaged readers produced more reviews than a platform campaign reaching 2,000. Engagement is not a function of list size. If you have been building a genuine relationship with your readers — through a newsletter, a reader group, or consistent social media presence — those readers will show up for you in ways that cold platform traffic will not. Start building that list now, even if your first book is months away. The author email list guide is the place to start.
Treat ARC readers as collaborators, not a marketing channel. The authors who run the most successful ARC campaigns are the ones who genuinely value reader feedback, not just the reviews. When you frame the ask as "help me make this book better before it reaches a wider audience," you attract readers who take the role seriously. Those readers finish. They post. And they come back for the next book.
Plan your ARC campaign alongside your Amazon Ads strategy. Reviews and advertising work together. A campaign with no reviews is expensive to run because click-through rates are lower and conversion rates are worse. A book with twenty reviews before you switch on Amazon Ads will perform significantly better than one with none. For the advertising side of this, the Amazon Ads for authors guide covers the practical setup.
Do not wait for the perfect moment. The most common reason authors do not run ARC campaigns is that they are waiting until the book is "really ready." The book is never really ready. Set a launch date, work backwards six to eight weeks, and start recruiting. Imperfect execution six weeks out beats perfect preparation that never begins.
Frequently Asked Questions
Can ARC readers post Amazon reviews if they did not buy the book?
Yes. Amazon's current policy permits reviews from readers who received a free copy, provided they disclose the arrangement and were not paid specifically for a positive review. A simple line — "I received an advance review copy of this book" — is sufficient disclosure. What Amazon prohibits is payment tied to a positive outcome, not the distribution of free copies for editorial purposes.
How many ARC readers do I need for a successful launch?
Aim for 40–60 sign-ups to land 15–25 posted reviews, accounting for readers who do not finish or do not post. Fifteen to twenty-five reviews on launch day is enough to give a new book credibility and a meaningful signal to the Amazon algorithm. More is better, but diminishing returns set in above around 50 reviews for most categories.
Which is better — BookSirens or BookSprout?
It depends on your genre. BookSirens performs better for most fiction genres — fantasy, science fiction, thriller, literary fiction, and YA. BookSprout performs better for romance, Christian fiction, and nonfiction. BookSprout's free tier (up to 20 copies) makes it the lower-risk starting point if you are testing ARC campaigns for the first time. BookSirens' Promote Plan at $10 per book plus $2 per download offers more transparency on costs for larger campaigns.
What format should I send ARC copies in?
EPUB is the most versatile format — it works on Kindle, Kobo, and most reading apps. PDF is an acceptable fallback for readers without a dedicated e-reader. Do not send Word or Google Docs files. If you are using BookSirens, BookSprout, or BookFunnel, the platform handles delivery once you upload your file. For guidance on producing a clean EPUB, see the EPUB validation errors guide.
Can ARC readers post reviews before the book is live on Amazon?
On Goodreads, yes — at any point. On Amazon, the product page needs to exist first. If you have set up a pre-order, the page is live and reviews can go up immediately. If you are doing a launch-day publish, readers will need to wait until the page appears — typically within 24–72 hours of upload.
Will Amazon remove ARC reviews?
It can happen, particularly if the reviewer's account is new or has no prior review history. There is no guaranteed way to prevent this, but recruiting readers with established Amazon accounts and review histories significantly reduces the risk. Staggering your outreach so reviews do not all appear on the same day also helps avoid triggering Amazon's pattern-detection systems.
Do I need to register my ARC campaign officially?
No. There is no formal registration process. "ARC" is industry shorthand, not a legal category. You are distributing early copies — the only requirements are that reviewers disclose the free copy and are not paid for a positive review, in line with Amazon's review policy.
How does an ARC campaign fit with Kindle Unlimited?
If your book is enrolled in KDP Select and therefore Kindle Unlimited, you are required to distribute digital content exclusively through Amazon. Distributing EPUB files to ARC readers before publication is generally understood to be pre-publication review distribution rather than commercial distribution, and is standard practice. However, once the book is live, you cannot distribute it digitally outside Amazon while enrolled in KDP Select. For a full breakdown of the trade-offs, see the KDP Select vs wide distribution guide.
What is the biggest reason ARC campaigns fail?
Starting too late. Authors who send ARCs two weeks before launch date will find that most readers have not finished in time, and reviews that trickle in after the first week of launch carry less algorithmic weight than those posted immediately. Start your campaign 6–8 weeks before launch, send files no later than five weeks out, and set a clear review deadline.
