What actually sells books?
In rough order of effect: the cover and the blurb, the first ten pages, being findable in the right category, a mailing list you own, and readers telling other readers. Social media posting, launch parties and paid press releases sit far below all of those, and absorb most of the effort most authors spend.
Ranked by evidence, not by enthusiasm
The bottom four are where most first-time authors spend most of their effort. That is the finding worth sitting with.
| What | How much it moves copies | Cost | Honest note |
|---|---|---|---|
| Cover that signals the right genre | Very high | £250–£800 | The single highest-leverage purchase. Nothing downstream compensates for it. |
| Blurb that makes the promise clear | Very high | £100–£350 | Read more often than any page of the book. Usually written last, in twenty minutes. |
| First ten pages holding | High | Your own time | The sample is the actual sales page. Most abandoned purchases happen here. |
| Correct categories and keywords | High | Free | Being in the right small category beats being invisible in a large one. |
| A mailing list you own | High, and compounding | Free to low | The only audience nobody can take away from you. Start it before the book. |
| Reader word of mouth | Highest of all, and unbuyable | Free | Everything above exists to make this possible. |
| Reviews, especially early ones | Moderate | Free (ARC readers) | Twenty honest reviews change conversion. Paid reviews violate platform terms. |
| Paid advertising | Moderate — but only after the above | £5–£20 a day | Advertising a book with a weak cover or blurb spends money faster, not better. |
| Organic social posting | Low for direct sales | Your time | Good for building an audience over years. Poor as a launch tactic. |
| Launch party | Very low | £100–£500 | Lovely. Do it for yourself, not for sales. |
| Paid press release distribution | Very low | £100–£400 | Almost never produces coverage or sales. This is the clearest 'don't' on the list. |
A separate free preview: A free outside view of your own pages
A separate editorial preview of one extract; it does not read the whole book or do the specialist job this page describes. Send up to 5,000 words. You get back what the draft appears to be doing to somebody who wasn't there when you wrote it, the strongest thing in it named, the exact place a reader starts to drift, and three revision priorities in order.

The uncomfortable finding
Almost everything that sells books happens before the launch, and most of it is about the book rather than the promotion.
A book with the right cover, a clear blurb and a strong opening will sell steadily with almost no marketing. A book with a weak cover and a vague blurb will not sell no matter how much marketing is applied — and paid advertising simply makes that failure faster and more expensive.
This is unwelcome news, because the book is finished and the marketing feels like the part still available to influence. But the highest-return action for most self-published authors is a better cover, not a bigger campaign.
Categories and keywords are the cheapest win available
Free, takes an afternoon, and consistently underdone.
Being ranked in a smaller, accurate category is worth far more than being invisible in a huge one. A book that reaches the top twenty of a specific sub-category gets shown to people browsing that sub-category; a book at rank 40,000 in a broad category is shown to nobody.
Spend real time on this. Look at what the books genuinely like yours are categorised under, not what sounds impressive. And keywords should describe what a reader would type when they do not know your book exists — which is almost never your title.
The mailing list is the only audience you own
Social platforms lend you an audience and can withdraw it without notice — through an algorithm change, an account problem, or simply by becoming somewhere people no longer are.
A mailing list is portable, and it works: a list of 500 engaged readers reliably outperforms 10,000 passive social followers at launch, because email arrives rather than waiting to be scrolled past.
Start it before the book is finished. Offer something worth having — a chapter, a related guide, a genuinely useful checklist — and write to them occasionally about something other than buying your book. By book two it is the most valuable asset you have.
What doesn't work, plainly
Paid press release distribution. The clearest waste on the list. Journalists do not read distribution wires for book news.
Posting your buy link repeatedly on social media. It does not convert, and it costs you the audience you were building.
Paid reviews. Against the terms of every major platform, and detectable.
Blog tours, mostly. Sites with no readership reviewing books for free traffic.
Launch parties, for sales. Have one because finishing a book deserves marking. Do not expect it to move the numbers.
Advertising a book that isn't converting yet. If your sample-to-purchase rate is poor, advertising increases the number of people who don't buy.
About Your Book Pro
Your Book Pro is a book-writing platform built in Britain. Start with an idea, notes, half a draft, a podcast, or a finished manuscript, and use our purpose-built AI tools for planning, feedback, editing, proofreading, cover designs, and to create print-ready files. Writing is totally free: you can type, upload or speak your book as much as you like, and use only the editing tools you need with Plus, or go unlimited with Pro.
Produce world-class drafts at the fraction of the cost of hiring a human editorial team.
Every account starts with 1,000 welcome credits, and a plain export of your own words is free.
Each guide says plainly when a person does the job better than AI. Guides on legal topics are general information, not legal advice.
Marketing Guidance builds a launch plan for the book you actually have — genre, audience, format, whether there is a list, whether it is a first book — and it is deliberately honest about what will not work for your particular case. A local history book and a cosy mystery need almost nothing in common.
It sits after the two things that matter more: Generate a Cover and Back-Cover Blurb, because a plan cannot rescue a book that is signalling the wrong genre. If you only do one thing from this page, do those two.
And here is what we do not have: a publicist has relationships, built over years, with people who commission coverage. That is what you are buying at £1,500–£5,000 a month, and it cannot be generated. For most self-published books it is not the right spend — but when it is, it is genuinely not something a tool replaces.

Draft a cover and blurb first
Email me my free review linkQuestions people ask
- How much should I spend marketing a self-published book?
- Put the money into the cover and blurb first. Beyond that, £5–£20 a day on ads once your sample-to-purchase rate is healthy, and nothing at all before that.
- Do I need a website?
- A simple one, mostly so there is somewhere to collect email addresses and somewhere for people who search your name. It does not need to be elaborate and it does not sell books on its own.
- How many reviews do I need?
- Around twenty honest reviews is where conversion measurably improves. Get them from ARC readers before launch, never by paying, and never by asking friends to say they loved it.
- Is BookTok worth it?
- For some fiction genres, enormously — and it is not something you can reliably manufacture. It rewards people who are genuinely part of the community rather than authors arriving to promote.
- Should I do a blog tour?
- Rarely worth the time. A single review on a site your readers actually read beats twenty on sites nobody visits.
