How to market a self-published book in 2026
Self-published authors grow through TikTok and an email newsletter. This blueprint sets out what to post and how often, the season, the rules on claims and reviews, and the first 90 days, from 28 sources checked in October 2026.
Core channels:TikTokEmail newsletter
Where to show up
Core channels get most of the hours. Support channels get a little. The rest can wait until the core ones work.
| Channel | Role | Why |
|---|---|---|
| TikTok | Core | Fiction readers swap and find books by trope, mood and cover on BookTok. We found no 2025-26 survey that measures its effect on indie sales (Written Word Media 2025 does not rate TikTok or Instagram), so treat it as free reach that feeds the list, not as the revenue lever; in that survey the levers are the author's email list, promo sites, Facebook ads and lead magnets. Guides say it suits trope-driven fiction such as romance and fantasy; non-fiction authors use LinkedIn first. |
| Email newsletter | Core | The strongest lever in the best survey we found. In Written Word Media's 2025 survey (1,346 indie authors, self-reported), authors with a mailing list had a median income of about $300 a month against about $15 without, and authors earning over $10,000 a month rate newsletters 4.3 out of 5 against about 2.7 for those under $100. It is correlation, not proof. |
| Support | Bookstagram is a reader community built on covers, shelves and quotes. Instagram's head says sends per reach count slightly more than likes for reaching people who do not follow you (Mosseri, Jan 2025), so a quote card or cover shot a reader sends to a friend beats a plain announcement. No sales-effect data found, so reuse the TikTok clips as Reels. | |
| Support | For non-fiction and business authors the book is a credential that sells services: non-fiction was 6% of respondents in Written Word Media 2025, rare among the highest earners, and its income often comes from adjacent services. LinkedIn is where buyers of that expertise are. Fiction authors skip it. | |
| Support | Facebook Ads are rated among the most effective for authors who learn the system (Written Word Media 2025), and this is a niche that scales on paid ads: authors earning over $10,000 a month spend about $4,500 a month on marketing against about $81 for those under $100 (self-reported). A small team starts with a reader group and adds ads once the series and the list are ready. | |
| Support | Mostly peers: r/selfpublish says it is not a place for self-promotion and keeps a weekly self-promo and chat thread (GummySearch listing, 2026). Use Reddit to learn what readers ask and to answer, not to sell. | |
| Skip | No 2025-26 evidence found that Pinterest sells indie books. The exception is visual non-fiction (cookbooks, crafts, home), where blog pins can feed readers (guides say). | |
| YouTube | Skip | No indie-author evidence found. A non-fiction author who already films talks can reuse them, but it is not worth a new habit for a small team. |
| X | Skip | Nothing in the 2025 indie-author survey or our other sources shows X selling books. Keep the handle claimed. |
| Threads | Skip | No book-sales data found for Threads. Cross-post Instagram text posts only if it is automatic. |
| Quora | Skip | No evidence that Quora sells indie books. A non-fiction author who already writes answers can reuse them, but it is low priority. |
| Google Business Profile | Skip | Google gives a profile to a business with a location customers visit or that travels to customers (Google Business Profile guidelines); most authors have neither. |
Who buys and how they choose
Readers who buy by genre, trope, cover and series, and non-fiction readers who buy to solve a problem and sometimes hire the author. Fiction readers read in volume and often through Amazon's subscription, which KDP's own pages now call Kindle+ (KDP Select authors earned $69.3 million for September 2026, KDP help page). In Written Word Media's 2025 survey of 1,346 indie authors (self-reported), romance was 21% of respondents but about 44% of those earning over $10,000 a month, so in this sample the heavy-reading genres carry the income.
Fiction: a reader sees a cover, trope tags and a short blurb, reads the sample, and buys or borrows in one sitting; a reader who likes book 1 is the cheapest sale for book 2, which is why series carry the income (authors earning $1,000 or more a month almost always have more books, often 10+, and very often write series: Written Word Media 2025, self-reported). Subscribers read at no extra cost and the author is paid for pages read the first time (KDP). Non-fiction: the reader researches a problem for days or weeks, checks reviews and the author's other content, and the book often sells the author's services (non-fiction income often comes from adjacent services: Written Word Media 2025). By genre in that sample: romance, paranormal romance and cozy mystery over-index among high earners; children's, literary fiction and young adult are rare among them. Launch timing matters most for existing fans; new readers arrive later through search, lists and ads.
Where buyers find businesses like this
- Amazon search and category lists — KDP allows up to seven keywords and up to three categories per title. Best Sellers Rank reflects customer activity relative to other books, recent activity weighted more heavily, updated at least daily with up to two days' lag (KDP help, 2026).
- The author's own email list — Authors with a list had a median income of about $300 a month against about $15 without; average list size rises from 902 subscribers (under $100 a month) to 18,327 (over $10,000 a month) (Written Word Media 2025, self-reported, correlation).
- Promo and newsletter sites (Freebooksy, Bargain Booksy, BookBub Featured Deals) — Rated among the most effective tactics in Written Word Media's 2025 survey.
- Facebook Ads, for authors who learn the system — Rated among the most effective in Written Word Media's 2025 survey; Amazon Ads and BookBub Ads were rated mixed and hard to optimise.
- BookTok and Bookstagram reader communities — No 2025-26 survey in our sources measures their effect on indie book sales; Written Word Media 2025 does not rate TikTok or Instagram. Guides say readers search by trope and cover.
- Goodreads — Any author can join the Goodreads Author Program free; it offers a profile, blog feed, giveaways, ads and Ask the Author (Goodreads). Giveaway prices not verified.
- Series read-through from book 1 — Authors earning $1,000+ a month almost always have more books and very often write series (Written Word Media 2025, self-reported).
The first 90 days
Week 1
Write the reader promise in one sentence.
Fiction: genre, trope, tone and heat or content level. Non-fiction: the problem, the reader, the result.
Week 1
Fix the shelf. A cover in the style of the genre's bestsellers; a blurb with the trope in the first line; up to seven specific keywords (settings, character types, plot themes, tone) and up to three categories that match the book; A+ Content (live within eight business days); no URLs, reviews or prices in the description (KDP).
Weeks 1-2
Build the reader magnet (a free prequel, novella, first chapters or a checklist), put its link in the back matter of every book, connect it to the newsletter tool and write the four-email welcome run. Claim your Amazon author page and the free Goodreads author profile.
Week 2
Decide KDP Select or wide.
Select is a free 90-day enrolment; guides say it requires ebook exclusivity on Amazon, so read the terms first. In Written Word Media 2025, 38% of authors kept all books in Select and 30% none; among those earning over $5,000 a month, 43% were fully in Select and 15% fully wide (self-reported). A first series in a subscription-heavy genre (romance, fantasy, LitRPG) usually starts in Select; this is a judgement, not a rule.
Weeks 2-3
Build the ARC team from your list and followers.
Send a free copy, require no review, and ask readers to say they got a free copy (KDP; FTC).
Weeks 3-4
Batch-film 12 vertical videos (trope pitch, reader reaction, author at work, recs) and 4 quote carousels.
Schedule 3 videos a week on TikTok and Reels.
Weeks 4-6
Set the pre-order with the final ebook file in at least 72 hours before release (paperback at least five days; KDP Timelines).
Run the ARC call three weeks out.
Week 6
Launch. Email the list first, ARC readers post reviews on release day, price book 1 low for launch week and submit it to promo sites (rated among the most effective in Written Word Media 2025).
Weeks 7-12
Write and release book 2 on a fixed date.
In Written Word Media 2025, about 80% of authors with 1-3 books earned under $100 a month, while authors with 25+ books had a median of about $3,000: the catalogue is the plan.
Week 10
If book 1 has a book behind it and the list is growing, test Facebook ads on book 1 with a small daily budget.
Facebook Ads are rated effective for authors who learn them; Amazon Ads and BookBub Ads are rated mixed (Written Word Media 2025).
Week 11
Apply for a BookBub Featured Deal for book 1 during a time-limited price drop.
Check the current criteria on BookBub Partners;
Week 12
Review list growth, book 1 sales and page reads, read-through to book 2, and which short-video format drew the most sends.
Cut the rest. Non-fiction: add one podcast pitch and one speaking pitch a month.
Channel by channel
TikTok · core
Fiction readers swap and find books by trope, mood and cover on BookTok. We found no 2025-26 survey that measures its effect on indie sales (Written Word Media 2025 does not rate TikTok or Instagram), so treat it as free reach that feeds the list, not as the revenue lever; in that survey the levers are the author's email list, promo sites, Facebook ads and lead magnets. Guides say it suits trope-driven fiction such as romance and fantasy; non-fiction authors use LinkedIn first.
Rhythm: 3 videos a week from one two-hour batch session; in the launch fortnight, one a day.
| Format | Share | How a good one is built |
|---|---|---|
| Trope-and-cover pitch | about 30% | 0-2 s: the trope or situation as on-screen text over the book in hand. 2-10 s: three quick beats of the premise, no spoilers. 10-15 s: heat level or content note, and 'link in bio'. Caption: the trope words readers search. — Readers choose by trope and tone (guides say). |
| Reader reaction | about 20% | With permission, film or stitch a real reader's reaction. First frame shows their face and the page. Caption quotes them; tag them; say they got a free copy if they did. — Social proof from a person who is not the author (guides say). |
| Author at work | about 20% | A scene being drafted, a revision note, a playlist, a character mood board. Say the stakes out loud in the first line. — Gives readers a person and a reason to follow the series (guides say). |
| Recs as a reader | about 20% | Three books in your genre in 15 seconds, covers on screen, one line each. Put your own among them, last, if it fits. — Authors who recommend others earn trust (guides say). |
| Launch countdown | about 10% | From two weeks out: cover reveal, one line from chapter one, ARC reactions, then 'out now' with the retailer link in bio. — Concentrates attention into launch week. |
What to post about
- Tropes and the reader promise
- Series world and characters
- The author as a reader: recommendations
- Reader reactions
- Writing life and process
- Release countdowns
Openings that work
- Trope: 'If you like grumpy-sunshine with a murder to solve, start here'
- Content note: 'Closed door or open door? Here is my heat level'
- Series entry: 'Book 1 of 6, and the whole series is out'
- Recs: 'Books that ruined me, in a good way'
How people find you here: TikTok search with trope, genre and mood words in the caption and on-screen text; reader reaction videos and duets; the BookTok community (guides say).
How a viewer becomes a client: Link in bio to one page: book 1 on Amazon (and other retailers if wide), then the reader-magnet sign-up. Pinned comment names the book and the series order.
Avoid on TikTok
- Do not offer free copies for five-star reviews; Amazon invalidates reviews given for anything beyond a free or discounted copy (KDP).
- Do not buy followers or views (FTC Aug 2024 rule).
- Disclose free copies and any payment in the video itself (FTC Disclosures 101).
- If you use a TikTok Business account, the in-app picker shows only the Commercial Music Library, and the general library is not cleared for brand or business content (TikTok for Business help).
- Do not spoil the twist or the ending.
Email newsletter · core
The strongest lever in the best survey we found. In Written Word Media's 2025 survey (1,346 indie authors, self-reported), authors with a mailing list had a median income of about $300 a month against about $15 without, and authors earning over $10,000 a month rate newsletters 4.3 out of 5 against about 2.7 for those under $100. It is correlation, not proof.
Rhythm: Fiction: two emails a month plus a launch run (cover reveal, pre-order, release day, one week later). Non-fiction: one useful email every one to two weeks.
| Format | Share | How a good one is built |
|---|---|---|
| Reader-magnet welcome run | about 20% (automatic) | Email 1 delivers the free story, first chapters or checklist. Email 2, day 2: who you are and one personal detail, with book 1. Email 3, day 5: the series reading order. Email 4: one question the reader can answer by replying (favourite trope, favourite character). — Lead magnets are among the most effective tactics in Written Word Media 2025; the run turns a freebie hunter into a reader. |
| Release email | about 25% | Subject: the book and the offer ('Book 3 is out; Book 1 is $0.99 this week'). Cover, a two-line hook with no spoilers, one button per retailer, a P.S. about the next book. — Launch sales come from the list first, and Amazon's rank weights recent activity more heavily (KDP). |
| Behind-the-book letter | about 30% | 150-250 words: the scene you cut, the real place behind the setting, the playlist. One question at the end. — Keeps readers warm between releases (guides say). |
| Recommendation | about 15% | Two books you read in your genre, one line each. No swaps with off-genre lists. — Newsletter swaps are trending down in Written Word Media 2025; use sparingly. |
| ARC call | about 10% | Three weeks before release: 'Want to read Book 3 early?' with a form, the date reviews may go live, and the rule: honest review, no obligation, mention the free copy. — ARC readers seed the first reviews; KDP allows free copies if no review is required. |
What to post about
- Series news and release dates
- Behind the book
- Free reads and extras
- Reader polls and questions
- Deals
Openings that work
- Offer plus fact: 'Book 3 is out Friday; the list gets it at $0.99 for 48 hours'
- Cliff-hanger: 'She had one hour to decide who to trust'
- Personal: 'The scene I almost cut from Book 2'
- Question: 'Which trope should I write next?'
How people find you here: Not a discovery channel. Sign-ups come from the reader magnet in the back matter of every book, the author website, social bios, ARC and giveaway forms, and promo-site giveaways (guides say).
How a viewer becomes a client: Release emails drive first-week sales; each email has one main retailer button; the welcome run moves a reader from book 1 to book 2.
Benchmarks: Average list size by monthly income: under $100, about 902; $100-500, 1,405; $500-1,000, 2,743; $1,000-5,000, 3,986; $5,000-10,000, 7,488; over $10,000, 18,327 (Written Word Media 2025, self-reported).
Avoid on Email newsletter
- Do not buy lists or add people without consent. US CAN-SPAM needs accurate sender details, honest subject lines, an ad disclosure, a postal address and an opt-out honoured within 10 business days; penalties up to $53,088 per email (FTC).
- Do not offer anything beyond a free or discounted copy for a review, and do not require a review; Amazon invalidates the review (KDP Customer Reviews help).
- Do not offer incentives for reading in Kindle+ (payment, bonus content, contest entries, discounts or gifts); KDP Select bans it.
- Do not put the reader-magnet link in the book description; KDP descriptions cannot hold URLs. Use the back matter (guides say).
Instagram · support
Bookstagram is a reader community built on covers, shelves and quotes. Instagram's head says sends per reach count slightly more than likes for reaching people who do not follow you (Mosseri, Jan 2025), so a quote card or cover shot a reader sends to a friend beats a plain announcement. No sales-effect data found, so reuse the TikTok clips as Reels.
Rhythm: 3-4 posts a week: Reels from the TikTok batch, one quote carousel, Stories on release days.
| Format | Share | How a good one is built |
|---|---|---|
| Quote carousel | about 30% | Slide 1: the most shareable line, large. Slides 2-4: the scene around it, a few words each. Last slide: title, series number, 'link in bio'. — Quotes are what readers screenshot and send (guides say). |
| Cover and shelf Reel | about 25% | Cover in hand or on a shelf with a trope line on screen for the first two seconds, three quick cuts of the set-up, end on the series order. — Covers sell the genre promise at a glance (guides say). |
| Reader photo as a Collab post | about 20% | Invite the ARC reader or reviewer as a Collab co-author so the post shows on both profiles. Caption quotes their own words; disclose the free copy. — Reaches the reader's followers, who read the same genre (guides say). |
| Character or aesthetic board | about 15% | Six images and one line per character, or a mood board with the setting, the tone and the trope in text. — Gives browsers a feel for the book without spoilers (guides say). |
| Stories: countdown, poll, link sticker | about 10% | Release countdown, a two-cover poll, the link sticker on release day. — Keeps the existing audience close at launch (guides say). |
What to post about
- Covers and shelves
- Quotes
- Characters and aesthetic boards
- Reader photos and the ARC team
- Release countdowns
Openings that work
- Quote: the first slide is the most shareable line
- Question: 'Which side of the love triangle are you on?'
- Aesthetic: 'Dark academia, but make it a romance'
How people find you here: Reels recommendations; Collab posts with readers and reviewers; trope and genre words in captions; saves and sends.
How a viewer becomes a client: Link in bio to the book page and the list sign-up; link sticker in Stories on release days.
Avoid on Instagram
- Do not buy followers or views; the FTC's August 2024 rule bans it for commercial use.
- Do not trade gifts or money for reviews; Amazon invalidates reviews given for anything beyond a free or discounted copy (KDP).
- Disclose free books sent to reviewers and any paid partnership (FTC Disclosures 101).

For non-fiction and business authors the book is a credential that sells services: non-fiction was 6% of respondents in Written Word Media 2025, rare among the highest earners, and its income often comes from adjacent services. LinkedIn is where buyers of that expertise are. Fiction authors skip it.
Rhythm: 2-3 posts a week for non-fiction authors.
| Format | Share | How a good one is built |
|---|---|---|
| One idea from a chapter | about 40% | Hook line with a claim or a number. A 6-8 line story. One takeaway. No link in the post; put it in the first comment (guides say). — Shows the thinking that the book sells. |
| Framework carousel (document post) | about 30% | Slide 1: the promise. Slides 2-7: one step each with a one-line example. Last slide: where to get the full checklist (the newsletter). — Saves and shares; carries the book's method (guides say). |
| What writing and publishing taught me | about 15% | One mistake, one fix, one number. — Builds trust with other professionals. |
| Client or reader story | about 15% | With written permission: the problem, what they changed, the result, the chapter that helped. — Turns the book into proof. |
What to post about
- The book's method in small pieces
- Case stories with permission
- Industry commentary
- Behind the book
Openings that work
- Counter-intuitive claim from the book
- A number plus a story: 'We cut onboarding from 14 days to 3'
How people find you here: LinkedIn feed through your network; search on your topic words in the headline and About section; comments on others' posts.
How a viewer becomes a client: Newsletter sign-up for a chapter or checklist; a booking page for talks and consulting; bulk orders for companies (guides say).
Avoid on LinkedIn
- Do not post only the Amazon link.
- Do not tag people to ask for reviews.
- Disclose any affiliation or free copy when you recommend a book (FTC Disclosures 101).
Facebook · support
Facebook Ads are rated among the most effective for authors who learn the system (Written Word Media 2025), and this is a niche that scales on paid ads: authors earning over $10,000 a month spend about $4,500 a month on marketing against about $81 for those under $100 (self-reported). A small team starts with a reader group and adds ads once the series and the list are ready.
Rhythm: Reader group: 3 posts a week. Ads: only when book 1 has a series behind it and a reader magnet in place (guides say); start with a small daily budget.
| Format | Share | How a good one is built |
|---|---|---|
| Reader-group post | about 50% | A poll ('which cover?'), a character question, a sneak-peek line or an ARC call. Same time each day; reply to every comment. — Keeps the readers who already like the series close (guides say). |
| Book 1 ad | about 30% of the effort | Image: a cover in the genre's style. Text: the trope hook, the price or 'free', one button to the retailer page or the reader magnet. Audience: readers of similar authors. — Where the niche's top earners spend their money (Written Word Media 2025). |
| Launch event | about 20% | Cover reveal and release-day party in the group with a giveaway of a signed print copy, entry by comment only and never tied to a review. — Gives the group a date to rally around. |
What to post about
- Series news
- Character polls
- Behind the book
- ARC calls
- Release-day events
Openings that work
- Poll: 'Which cover do you want for Book 4?'
- Ad: 'If you love [trope], Book 1 is free this week'
How people find you here: Reader groups in your genre (join as a reader first), your own group, ad targeting by similar authors (guides say).
How a viewer becomes a client: Group posts send readers to the retailer page and the list; ads send to book 1 or the reader magnet.
Benchmarks: Average monthly marketing spend by income: over $10,000, about $4,500; $5,000-10,000, $1,362; $1,000-5,000, $478; $500-1,000, $275; $100-500, $152; under $100, $81; overall $636 (Written Word Media 2025, self-reported). Amazon Ads and BookBub Ads are rated mixed (same survey).
Avoid on Facebook
- Do not run ads for a stand-alone book with no series or list behind it; the money comes back through read-through (guides say).
- Do not join review-swap groups: Amazon bars compensated reviews and the FTC bans buying reviews.
- Do not drop a link and leave in other authors' groups; read the rules.
Reddit · support
Mostly peers: r/selfpublish says it is not a place for self-promotion and keeps a weekly self-promo and chat thread (GummySearch listing, 2026). Use Reddit to learn what readers ask and to answer, not to sell.
Rhythm: Answer two or three questions a week; one entry in the weekly self-promo thread when you have news.
| Format | Share | How a good one is built |
|---|---|---|
| Help-first answer in r/selfpublish | about 60% | Answer a question about covers, KDP, ads or formatting with your own numbers and no link. — Earns standing with peers before any mention of your book. |
| Weekly self-promo thread entry | about 20% | Two lines: genre, premise, price, one link; follow the thread's template if it has one. — The place the sub provides for it. |
| Labelled promo post in genre subs | about 20% | Use the promo flair where one exists (r/litrpg lists Promo: E-book, Audiobook and Webnovel flairs), follow the sidebar, and give one honest line on the book. — Labelled promotion is how genre subs let authors post. |
What to post about
- Self-publishing questions
- Launch results shared as lessons

- Numbers first: 'I tested two covers; here is what changed'
How people find you here: Subreddit search, weekly threads, recommendation threads in genre subs.

- Do not ask for upvotes or reviews.
- Do not answer recommendation requests only to name your own book.

Google and the blog
Support channel. For fiction, the author site holds the newsletter form, the series reading order and 'books like' pages, which match what readers search. For non-fiction, the blog is the main discovery engine because the book is a credential. A small team keeps a short site and updates it on each release.
| Article | Searches like | How the winners are built |
|---|---|---|
| Series reading order | “[series name] reading order”, “[author name] books in order”, “how many books are in the [series name] series”, “is the [series name] series finished” | One page per series: a numbered list with cover, one-line blurb, year and a 'start here' note; content notes; retailer buttons for Amazon and other stores; last-updated date; newsletter form. |
| Books like [popular title] | “books like [title]”, “authors like [author]”, “if you liked [title] what to read next”, “best books with [trope]” | Short intro, 6-10 picks with covers and a line on why each matches (trope, tone), your own book as one honest entry among them, last-updated date. |
| Trope and genre explainer | “enemies to lovers books”, “best cozy mystery series for beginners”, “what is progression fantasy”, “closed door romance books” | Definition in two lines, 8-12 recommended books with covers, content notes, and the newsletter magnet. |
| Book page with content notes | “[book title] summary”, “[book title] content warnings”, “is [book title] a standalone”, “[book title] sequel” | Blurb, spoiler-free premise, content notes, series position, reading order link, retailer buttons. |
| Problem-solution article (non-fiction) | “how to [problem the book solves]”, “[problem] checklist”, “[problem] for beginners”, “best book on [topic]” | Answer in the first 100 words, numbered steps, one worked example, a checklist download, a soft link to the book. |
When searches peak: Reading-order and 'books like' pages are evergreen: update them on each release. Non-fiction: January resolutions and September 'back to work' (guides say). Fiction: romance around Valentine's Day, horror and mystery in October (guides say). Publish seasonal pages 4-8 weeks ahead.

Communities on Reddit
Read the rules and the top threads before you post. Most of these remove promotion; a useful answer is what earns a visit.
| Subreddit | Who is there | What works and what is allowed |
|---|---|---|
| r/selfpublish · about 269k | peers | Help-first answers on covers, KDP, ads and formatting; launch lessons shared with numbers and no links. Promotion: The description says it is not a place for self-promotion; a Weekly Self-Promo and Chat Thread exists (GummySearch listing, 2026). Read the live sidebar for limits. |
| r/books · about 27.3M | buyers | Honest reader replies in recommendation threads. Promotion: No rule text could be read. The description sends recommendation requests to the Weekly Recommendation Thread, so treat it as a readers' space and read the sidebar before naming your own book. |
| r/Fantasy · about 4.0M | buyers | Reader discussion and recommendation threads; labelled self-promotion only where the sidebar allows. Promotion: A self-promotion post flair appears in listings (for example a release announcement for a Kindle Unlimited book), so a labelled route exists; the rules were not verified. |
| r/RomanceBooks · about 542k | buyers | Recommendation threads and trope questions answered as a reader. Promotion: Described as a discussion sub for romance readers, built around recommendations; rules not verified. |
| r/litrpg · about 160k | both | Release and free-book announcements under the promo flair; progression and character discussion. Promotion: Promo flairs exist for E-book, Audiobook, Audiobook plus E-book and Webnovel, and listings show pre-order announcements and free-book offers (GummySearch listing, 2026); the limits were not verified. |

Partners who share your audience
- ARC readers and a street team: a free copy, no review required, an honest review welcome, and the free copy disclosed (KDP Customer Reviews help; FTC Disclosures 101).
- Promo and newsletter sites: Freebooksy, Bargain Booksy and BookBub Featured Deals were rated among the most effective in Written Word Media 2025; check current terms and prices yourself.

Rules that apply
- KDP (global): free or discounted copies may go to readers and reviewers if you do not require a review or try to influence it; anything more, such as a gift card, invalidates the review; reviews posted in exchange for compensation are not allowed (KDP Customer Reviews help, 2026).

- KDP metadata (global): title plus subtitle under 200 characters; no 'bestselling' or 'free'; no references to other authors without authorisation; descriptions with no URLs, emails, reviews, quotes or testimonials, review requests, pricing, promotions or time-sensitive information; keywords may not name other authors or sales rank (KDP Metadata Guidelines, 2026).
- KDP A+ Content (global): no pricing, promotions or time-sensitive wording, at most four quotes or endorsements, no links or language that redirects to other sites (KDP A+ Content pages, 2026).
- KDP AI rules (global): disclose AI-generated text, images or translations when you publish or republish; AI-assisted work, where you wrote it and AI helped edit or brainstorm, needs no disclosure; KDP caps new titles at 2 per format per week (KDP Content Guidelines and Create a Book help, 2026; check the current cap).

- US, FTC rule on fake reviews and social indicators (final rule Aug 2024): no fake or AI-generated reviews, no buying reviews tied to a sentiment, no buying fake followers or views for commercial use; reviews by insiders such as relatives need a clear disclosure (FTC press release).
- US, FTC Disclosures 101 (Nov 2019): disclose free products and perks given to reviewers and creators, in the post or video itself; '#ad' is fine.
- US email: CAN-SPAM requires accurate sender information, honest subject lines, an ad disclosure, a postal address and an opt-out honoured within 10 business days; up to $53,088 per email (FTC).
- TikTok (global): a Business account sees only the Commercial Music Library in the app, and the general library is not cleared for brand or business content (TikTok for Business help, 2026).
- UK and EU: marketing email to individuals generally needs prior consent under GDPR and PECR; not verified in this research, check the ICO or your national regulator.
What to measure
- Email subscribers and monthly growth. Reference points by monthly income: under $100, about 902; $1,000-5,000, about 3,986; over $10,000, about 18,327 (Written Word Media 2025, self-reported).
- Book 1 sales, borrows and Kindle+ pages read, and read-through to book 2 (no public benchmark found).
- Catalogue size: books in the series. In Written Word Media 2025, 1-3 books mostly earn under $100 a month and 25+ books have a median of about $3,000.
- Marketing spend against income. Reference points: about $478 a month at $1,000-5,000 income, about $4,500 over $10,000 (Written Word Media 2025, self-reported).
- Review count and rating on book 1 (no healthy range from a source).
- Amazon rank is relative, weights recent activity more heavily, and can lag up to two days (KDP); read it as a launch-week signal only.
- Short-video sends per reach and watch time, the signals Instagram says to watch (Mosseri, Jan 2025).
- Non-fiction: leads, talks and bookings from the book, not royalties (Written Word Media 2025 notes income often comes from adjacent services).

Questions
Asked about self-published authors
What is the best marketing channel for self-published authors?
TikTok and Email newsletter. Fiction readers swap and find books by trope, mood and cover on BookTok. We found no 2025-26 survey that measures its effect on indie sales (Written Word Media 2025 does not rate TikTok or Instagram), so treat it as free reach that feeds the list, not as the revenue lever; in that survey the levers are the author's email list, promo sites, Facebook ads and lead magnets. Guides say it…
How often should self-published authors post on TikTok?
3 videos a week from one two-hour batch session; in the launch fortnight, one a day.
Is X worth it for self-published authors?
Usually not at the start: Nothing in the 2025 indie-author survey or our other sources shows X selling books. Keep the handle claimed.
Which months matter most for self-published authors?
Every 90 days: KDP Select is a 90-day enrolment; you pick one promotion type per enrolment period, a Countdown Deal or a Free Book Promotion (KDP Select help). Plan the promotion for each term around a release or a book 1 push. Monthly: Kindle+ pages read are finalised near the 15th of the following month (KDP). KDP Select authors earned $69.3 million for September 2026 (KDP help banner).
What advertising rules apply to self-published authors?
KDP (global): free or discounted copies may go to readers and reviewers if you do not require a review or try to influence it; anything more, such as a gift card, invalidates the review; reviews posted in exchange for compensation are not allowed (KDP Customer Reviews help, 2026). Rules differ by country: check the regulator's own page for where you sell.
