How to find beta readers (and brief them so the feedback is usable)

The most common mistake is recruiting from writing communities. Writers read like writers — they notice craft, and they tell you about craft. What you need is someone who reads your genre for pleasure and will put a book down without guilt.

The reliable free sources, roughly in order of how well they work:

Genre communities. Subreddits, Goodreads groups, Facebook groups organised around a genre rather than around writing. Read the rules; most have a specific thread or day for this and will remove you otherwise.

Your own newsletter or social following, however small. Forty people who chose to hear from you contains three excellent beta readers. Ask publicly and let them self-select — the ones who volunteer read faster than the ones you nominate.

Local libraries and writing circles. Undervalued, and disproportionately useful for memoir, local history and anything with a regional setting.

Critique swaps. You read theirs, they read yours. Slowest, most reciprocal, and the source most likely to produce a long-term reading relationship — which is worth more than any single round of feedback.

Marketplaces. £50–£200 a reader. What you're buying is a deadline.

Three to five per round, in two rounds rather than one. Send to two readers first. If both trip on the same thing, fix it before the other three see it — otherwise you will get five reports about a problem you already know about, and you will have burned five first impressions on a draft you could have improved in a fortnight.

Expect a third to drop out. Recruit accordingly, and be genuinely gracious about it: a reader who goes quiet has usually had a hard month, not a hard time with your book.

'Let me know what you think' produces 'I loved it, well done'. Not because your readers are being polite — though they are — but because you gave them no idea what would help.

A good brief does three things. It asks about experience, not quality: where did you stop, not was it good. It asks at fixed points, so you can compare readers to each other. And it gives permission to be unkind, explicitly and in writing, because most people need to be told twice.

Keep it to a page. Twelve questions is plenty; twenty-two is the full menu to choose from, not a form to send.

You will get contradictions, and this is where most authors lose their nerve.

The rule: count the symptom, ignore the prescription. If three readers say chapter nine dragged and each proposes a different fix, believe the drag and ignore all three fixes. If one reader hated something two readers loved, you have found the thing that makes your book specific — usually keep it, and make it more so.

Only act on a single reader's note when it names something you already suspected at three in the morning.

Name them in the acknowledgements, ask first, and send them the finished book in the format they read in. Offer to read theirs. A beta reader who felt useful will read your next book, and by your third book the readers you kept are worth more than any service you could buy.
