Last reviewed by Robert Prime — July 2026
The Verdict — July 2026: There is no single marketing channel that works for every book. But there is a reliable sequence: build an email list before launch, run Amazon Ads from day one, stack a BookBub Featured Deal if you can get one, and use social media (especially BookTok) as a free amplifier rather than a primary sales driver. The authors who fail at marketing are usually the ones who either spend nothing or scatter money across too many channels without giving any of them time to work. Pick two or three channels, commit to them for 90 days, then evaluate.
Marketing Channel Comparison
| Channel | Typical Cost | Time Investment | Best For | Limitations |
|---|---|---|---|---|
| Amazon Ads | £5–£30/day | Medium (ongoing optimisation) | Any genre on KDP, direct sales | Requires learning the platform, budget to test |
| Facebook/Meta Ads | £5–£20/day | Medium-high | Romance, thriller, non-fiction | Harder to track ROI, audience fatigue |
| BookBub Featured Deal | ~£90–£3,150 one-off (by category) | Low (application + setup) | Established books with reviews | Acceptance rate is low, not guaranteed |
| BookBub Ads (CPC) | £100+/month | Medium | International reach, author targeting | Higher CPC than Amazon, needs budget |
| Email list | £0–£30/month (email tool) | High (ongoing content) | All genres, long-term asset | Takes months to build, requires consistency |
| BookTok / social media | £0 | High (content creation) | YA, romance, literary fiction | Unpredictable, algorithm-dependent |
| Newsletter promo sites | £20–£300 per promo | Low | Price promotions, free runs | One-off spikes, not sustained |
| ARC campaigns | £0–£100 | Medium | Launch reviews | One-time per book |
The First 90 Days: A Launch Timeline
This timeline assumes you have a finished, formatted book ready to publish. If you are still in production, add 4–8 weeks before Day 1.
Pre-Launch (Days -60 to -1)
Day -60: Start building your email list if you do not have one. A simple landing page offering a free chapter or bonus content in exchange for an email address is enough. See our author email list guide for how to set this up from scratch.
Day -45: Begin your ARC campaign. Recruit 40–60 advance readers through platforms like BookSirens, BookSprout, or your own list. See our ARC platforms guide for which platform suits your genre.
Day -30: Set up your Amazon Ads account and familiarise yourself with Sponsored Products campaigns. Do not launch ads yet — learn the interface, research keywords, and prepare your campaigns. See our Amazon Ads for authors guide.
Day -14: Apply for a BookBub Featured Deal for launch week. Acceptance is not guaranteed, but the application is free and the payoff is significant if accepted. See our BookBub Featured Deal strategy.
Day -7: Email your list to announce the launch date. Post on social media. If you have a BookTok presence, create content around the book.
Launch Week (Days 1–7)
Day 1: Publish. Launch your Amazon Ads campaigns immediately — even a small daily budget keeps your book visible in search results during the critical first week.
Days 1–3: Email your list with the buy link. Ask ARC readers to post their reviews. Share on all social platforms.
Days 4–7: Monitor Amazon Ads performance. Pause keywords that are spending without converting. Increase budget on keywords that are working.
Post-Launch (Days 8–90)
Weeks 2–4: Continue Amazon Ads optimisation. Consider adding Facebook/Meta Ads if your genre responds well to visual advertising (romance, thriller, and non-fiction often do). See our Facebook Ads for authors guide.
Weeks 4–8: Evaluate which channels are producing results. Double down on what works. If your book has gathered 15+ reviews and is selling steadily, apply for BookBub Featured Deal again if the first application was rejected.
Weeks 8–12: Begin planning your next book or your next promotion cycle. Stack newsletter promo sites for a price promotion or Kindle Countdown Deal.

Channel-by-Channel Guide
Amazon Ads
Amazon Ads (Sponsored Products) puts your book in front of readers who are actively searching for books in your genre. This is the single most important paid channel for most UK self-published authors, because it reaches people who are already on Amazon with the intent to buy.
You set a daily budget (starting at £5–£10/day is sensible), choose keywords or product targets, and pay per click. The learning curve is real — expect to spend your first £50–£100 gathering data rather than generating profit.
For a full guide, see Amazon Ads for Authors.
Facebook and Meta Ads
Facebook Ads can drive traffic to your Amazon listing or to a landing page where readers join your email list. The platform's targeting options (interests, demographics, lookalike audiences) make it useful for genres with strong visual hooks — romance covers, thriller imagery, and non-fiction topics all perform well as ad creative.
The challenge is attribution: a reader clicks your Facebook ad, goes to Amazon, and buys your book — but Facebook cannot track that purchase, so measuring ROI requires manual tracking and patience.
For a full guide, see Facebook Ads for Authors.
BookBub Featured Deals
A BookBub Featured Deal is an editorial placement in BookBub's email newsletter, which goes to millions of readers segmented by genre. It is widely regarded as the single most powerful one-day promotion available to indie authors.
The cost depends on category, discount price and region — BookBub's own rate card runs from about $122 to $4,216 (roughly £90–£3,150 at mid-2026 rates). Check bookbub.com/partners/pricing for your exact category before budgeting, as BookBub reprices periodically. Acceptance is competitive — BookBub curates its selections and rejects the majority of applications. A strong cover, solid reviews, and a competitive price point improve your chances.
For strategy on getting accepted, see our BookBub Featured Deal guide. For the CPC ad platform (separate from Featured Deals), see our BookBub Ads guide.
Social Media: BookTok, Instagram, and Beyond
BookTok (the book community on TikTok) has become a genuine discovery channel for certain genres — particularly YA, romance, fantasy, and literary fiction. A single viral video can produce a sustained sales spike.
The reality for most authors: BookTok success is unpredictable and not repeatable on demand. It is worth creating content consistently, but it should not be your primary marketing strategy. Treat it as a free amplifier, not a sales channel you can control.
For a full guide, see BookTok Marketing and Social Media Book Marketing.
Email List Building
Your email list is the only marketing asset you fully own. Unlike Amazon's algorithm, Facebook's reach, or TikTok's feed, your email list does not change when a platform updates its rules.
Building a list takes time and consistency. Start with a reader magnet — a free short story, bonus chapter, or companion content — offered in exchange for an email address. Use a service like MailerLite or ConvertKit (both have free tiers for small lists).
For a full guide, see How to Build an Author Email List. For reader magnets, see our reader magnets and lead magnets guide.
ARC and Review Platforms
Reviews are social proof. A book with zero reviews on launch day is invisible to most readers. An ARC (advance review copy) campaign gets honest reviews posted before or on launch day.
For a comparison of platforms, see our ARC platforms guide.
Newsletter Promo Sites
Sites like Freebooksy, Bargain Booksy, Robin Reads, and ENT promote discounted or free books to their subscriber lists. They work best when stacked (multiple sites on the same day or consecutive days) during a KDP Select free promotion or Kindle Countdown Deal.
For a list of UK-relevant promo sites, see our newsletter promo sites guide.
Worked Example: First-Book Marketing Budget (GBP)
Here is a realistic marketing budget for a UK author launching their first self-published book — a fiction paperback and ebook on KDP.
Conservative Budget (£300 over 90 days)
| Channel | Budget | Notes |
|---|---|---|
| Amazon Ads | £200 | ~£2–£3/day for 90 days, enough to test and learn |
| ARC platform (BookSirens or BookSprout) | £30–£50 | One campaign, 20–40 ARC copies |
| Email tool (MailerLite free tier) | £0 | Free for up to 1,000 subscribers |
| Social media | £0 | Organic only — BookTok, Instagram, Facebook groups |
| Newsletter promo site (one Tier 2 or Tier 3) | £50–£80 | One stacked promo during a price promotion |
| Total | ~£300 |
Moderate Budget (£500–£800 over 90 days)
| Channel | Budget | Notes |
|---|---|---|
| Amazon Ads | £300–£450 | £3–£5/day, more room to test keywords and scale |
| Facebook/Meta Ads | £100–£150 | Test for 30 days, evaluate ROI |
| ARC platform | £30–£50 | |
| Newsletter promo stack | £100–£200 | 2–3 promo sites stacked on same days |
| Email tool | £0 | Free tier |
| Total | £530–£850 |
What NOT to spend on
- Paid book reviews: Against Amazon's terms of service and ethically questionable.
- Social media "growth" services: Bot followers do not buy books.
- Vanity press "marketing packages": Overpriced and typically ineffective. See our vanity publishing warning signs guide.
- Multiple channels simultaneously from day one: Spreading £300 across five channels gives you £60 per channel — not enough data on any of them to know what works.
Common Mistakes
Spending nothing on marketing. "If I write a good book, readers will find it" is the most expensive belief in self-publishing. Discoverability requires active effort, especially in the first 90 days when Amazon's algorithm is forming its view of your book.
Spending everything before launch. Marketing spend before your book is live generates awareness without a buy link. Save the majority of your budget for launch day onward, when every click can convert to a sale.
Chasing BookTok virality instead of building systems. A viral moment is wonderful if it happens, but it is not a strategy. Amazon Ads and email lists are systems — they produce predictable, repeatable results over time.
Running Amazon Ads without understanding the dashboard. Launching campaigns without monitoring ACoS (advertising cost of sale), pausing underperforming keywords, and adjusting bids is equivalent to throwing money into a hole. Spend time learning the platform before spending money on it.
Ignoring the email list. Every reader who buys your book and does not end up on your email list is a reader you have to pay to reach again for your next book. Build the list from day one.

Frequently Asked Questions
How much should a UK author spend on book marketing?
A realistic first-book budget is £300–£800 over the first 90 days, concentrated on Amazon Ads and one or two supporting channels. There is no minimum — you can market for £0 using social media and organic outreach — but some paid advertising accelerates results significantly. The key is not how much you spend but whether you track what works and cut what does not.
What is the best marketing channel for self-published books in the UK?
Amazon Ads is the highest-leverage paid channel for most genres, because it reaches readers who are already on Amazon looking for books. For free channels, an email list delivers the most consistent long-term results. BookTok is powerful for specific genres (YA, romance, fantasy) but unpredictable. Most successful indie authors use a combination of two or three channels rather than relying on one.
Do Amazon Ads work for UK authors?
Yes. Amazon Ads are available through the amazon.co.uk marketplace, and UK authors can run campaigns targeting UK readers specifically. The interface is the same as the US version. Starting budgets of £5–£10/day are enough to begin testing. See our Amazon Ads for authors guide for a detailed walkthrough.
How do I get a BookBub Featured Deal?
Apply through BookBub's partner portal. You need a professional cover, a competitive price point (ideally £0.99 or free), and at least a handful of positive reviews. BookBub is selective and rejects the majority of applications — but there is no cost to apply, so submit for every eligible book. See our BookBub Featured Deal strategy.
Should I use social media or paid ads to market my book?
Both, but with different expectations. Social media (BookTok, Instagram, Facebook groups) is free and builds long-term visibility, but results are unpredictable. Paid ads (Amazon Ads, Facebook Ads) cost money but produce measurable, controllable results. Start with organic social media before launch, add Amazon Ads from launch day, and layer in other paid channels as your budget allows.
