ARC readers vs beta readers: what they are and how to build a team

Beta readers and ARC readers do two different jobs at two different moments. Beta readers read an unpolished draft and give you private feedback so you can fix the book before it is final. ARC readers read a finished, edited copy shortly before launch and post a public review on or near release day. You use betas first, ARC readers last — and the two teams rarely overlap.

That is the whole distinction in a sentence. Below is the practical version: timing, numbers, where to find each, and the Amazon review rules that catch out first-time authors.

What is a beta reader, and what do they actually do?

A beta reader is a target-audience reader — not a professional editor — who reads your manuscript before it is finished and tells you, as a reader, what worked and what did not. Did the middle sag? Did they guess the twist on page ten? Did they care about anyone? You are after the honest, reader-level reaction you can no longer have yourself, because you have read the thing forty times.

Betas come before professional editing and final production, while the book can still change in meaningful ways. Their feedback is private — it goes to you, not the public — and it is allowed to be blunt. Good beta feedback reshapes a chapter, cuts a subplot, or flags a character nobody likes. That is the point: catch the big problems while they are still cheap to fix. It sits in the same family as a manuscript critique, just earlier and from real readers rather than an editor.

What is an ARC reader, and how are they different?

ARC stands for Advance Review Copy. An ARC reader receives a finished, fully edited copy of the book — usually a few weeks before publication — in exchange for an honest public review posted at or just after launch. They are not there to suggest changes; the book is locked. Their job is to seed reviews on Amazon, Goodreads and elsewhere so that when the book goes on sale, it does not sit there at zero ratings looking unloved.

This matters because early reviews are social proof. A book with twenty honest reviews on day one converts browsers far better than a blank one, and a healthy review count feeds the retailer algorithms that decide what to show. ARC readers exist to manufacture that first wave honestly — real readers, real opinions, simply delivered early. They are a core part of any sensible book launch checklist.

Beta readers vs ARC readers: the comparison

Factor	Beta readers	ARC readers
When	Before final edits and production	A few weeks before launch
What they read	An unpolished, near-complete draft	A finished, fully edited copy
Their job	Give feedback to improve the book	Post an honest public review
Feedback is	Private — straight to you	Public — on stores and Goodreads
Can the book still change?	Yes, that is the point	No, it is locked
How many	Roughly 5–15	As many as you can honestly recruit
Main risk	Vague praise instead of useful notes	Breaking Amazon's review rules

When do you use each — and do you need both?

The order is fixed because the jobs are sequential. Betas read while the book is still soft, so their notes can change it. ARC readers read after editing, typesetting and proofing, because a review of a draft is worthless — and unfair to you. Hand a beta a finished book and you have wasted the one chance to fix what they spot; hand an ARC reader a rough draft and you have published their disappointment.

Do you need both? For most authors, yes. They solve different problems: betas make the book better, ARC readers help the finished book sell. You can skip betas if you have already had a strong developmental edit and trust the structure, and you can skip an ARC round for a quiet release. But if the book matters commercially, run both — betas early, ARC readers late. Where each fits in the wider production path is laid out in our guide to how to self-publish a book.

How many readers do you actually need?

For betas, quality beats quantity. Around five to fifteen engaged readers is plenty; you want enough that patterns emerge — if four of seven stumble at the same chapter, that is signal, not taste — without drowning in contradictory opinions. Ten who finish and write you a paragraph each are worth more than fifty who never reply. Expect a chunk to drop out; over-recruit a little.

For ARC readers, more is better, within reason, because not everyone delivers. A common rule of thumb is that only a third to a half of ARC recipients actually post a review, so if you want twenty reviews at launch, send the copy to forty or fifty people. Track who you sent to and follow up gently near release day — never with pressure to be positive, only a reminder that the book is live.

Where do you find beta readers and ARC readers?

For beta readers, start close and widen out. Writing groups and critique circles, genre communities on Reddit and Discord, your newsletter list, and dedicated beta-reader services and forums all work. Avoid leaning only on close family and friends for betas — not for legal reasons here, but because they tend to be too kind to be useful. You want readers who will tell you the truth.

For ARC readers, build from your own audience first: your mailing list, social followers and anyone who loved a previous book. Beyond that, there are book-blogger networks, Goodreads groups, BookTok and bookstagram reviewers, and ARC-distribution platforms such as BookSirens, StoryOrigin and BookFunnel that connect authors with reviewers. The strongest ARC team is one you grow over time — a launch team that follows you from book to book, recruited partly through a strong back-cover blurb and a clear genre promise that attracts the right readers in the first place.

What are the Amazon review rules you must not break?

This is where good intentions get books in trouble, so read it carefully — and treat it as a live, jurisdiction-sensitive area. Amazon's Community Guidelines prohibit incentivised reviews: you may not offer money, free or discounted products, gift cards, refunds or any other value in exchange for a review. The single exception is Amazon's own Vine programme, which Amazon controls. (Amazon Community Guidelines.)

Amazon also bans reviews from anyone with a personal connection to the author — family and close friends included. So a glowing five-star review from your sister or your writing partner is against policy and can be removed, taking your credibility with it. Reviews must be honest and freely given; you can never require a positive review, a star minimum or specific wording in return for a copy.

So how is an ARC copy legal? Because the free book is given for reading, not bought-and-paid-for praise. The reviewer is free to say anything, including that they disliked it. The honest framing is: “here is a free advance copy; a review would be appreciated but is not required, and any opinion is welcome.” Two practical rules follow. First, ARC reviewers should add an FTC-style disclosure — a line such as “I received a free advance copy in exchange for my honest review” — at the top of the review. Second, ARC reviews usually will not carry Amazon's “Verified Purchase” badge, because no purchase was made; that is normal. (FTC endorsement guidance.)

Because these policies change and differ by region, confirm the current wording on Amazon's own guidelines page before you launch rather than trusting any summary, including this one. If a term here is unfamiliar, our publishing glossary explains the jargon in plain English.

How to run both teams without losing the plot

Keep it simple. Build a beta round in after the draft is readable but before you commission editing, give readers a deadline and three or four specific questions, and thank everyone whether or not they finish. Later, when the edited and typeset book is ready, send ARCs three to four weeks before launch with a clear, no-pressure note. Reuse the readers who delivered; quietly retire the ones who vanished.

Both teams depend on one thing you control entirely: the book has to be genuinely finished before the ARC stage. A reader who opens your advance copy and hits a misspelled chapter heading or a layout that breaks on their Kindle will say so — publicly. That is the quiet reason authors hand the production end to us: at Librum we build files to pass Amazon KDP, IngramSpark and every store first time, including an EPUBCheck-validated reflowable ePUB 3, so the copy your ARC team reviews is the copy that sells. If you want the finished book flawless before any reviewer sees it, start here and bring us your manuscript.
