Scroll-Stopping Books: How to Promote a Book on Social Media

By Kevin White — Founder & CEO, Spirit Media Publishing, and author of The Ultimate Book Marketing Guide.

To promote a book on social media, choose one or two platforms where your readers already spend time, post short videos and useful posts about the problem your book solves, not just the book itself, and keep a steady rhythm for months rather than a burst at launch. Lead with your story and your message; mention the book in the caption and the link, and end every post with one clear next step. Short vertical video, such as reels and Shorts, is the format that reaches new people fastest, while email turns followers into buyers. Ask readers for reviews and photos with the book, and share them. Measure what matters: clicks to your book page, email sign-ups and sales, not likes. Most authors see results after weeks of consistent posting, not from a single viral moment.

Key takeaway: promote the message first and the book second, on one or two platforms, with short video and a steady weekly rhythm that runs for months.

Which platforms sell the most books?

The best platform is the one your readers already use, and the numbers make the choice easier than it looks. Pew Research Center found in 2025 that 84% of U.S. adults use YouTube and 71% use Facebook, about half use Instagram, and 37% use TikTok, with roughly a quarter of adults on TikTok every day. For most Christian nonfiction, that points to three strong options. Facebook reaches church communities, small groups and readers over 40, and its groups are still where many ministry conversations happen. YouTube rewards teaching, interviews and sermons, and its videos keep being found in search for years. Instagram and TikTok reach younger readers through short video and personal stories. Start with one main platform and one secondary platform, not five. Posting well and often on two beats posting rarely everywhere, and it leaves you time to answer comments, which is where readers decide whether they trust you enough to buy your book.

What to post about your book

Most authors post about their book too much and about their reader too little. A reader follows you because you help them, so most of your posts should serve the person your book was written for. Use a simple mix. About half of your posts should teach: a short lesson, a story or a practical tip drawn straight from a chapter. A quarter should show the person behind the book: why you wrote it, what you are learning, the ministry or family it came from. The rest can be direct: the cover, a launch date, a reader's review, a photo of the book in someone's hands, a link to buy. Every post should end with one clear next step, such as a link to a free chapter, an email sign-up, or the book's page. Quotes from the book work best as short videos or simple text graphics with a single sentence. Avoid long promotional captions; one honest story will sell more copies than ten announcements. Keep a running list of ideas as you go: every reader question, every sermon illustration and every comment that sparks a conversation is a future post. Authors who keep that list never run out of things to say, and their posts sound like a real person talking rather than a marketing plan.

A simple weekly posting rhythm

Consistency is what makes social media work, so set a rhythm you can keep for at least three months. Here is a simple weekly plan for one main platform.

1. Monday: one short teaching video from a chapter.

2. Tuesday: a quote graphic or a carousel with three takeaways.

3. Wednesday: answer one reader question in a short video.

4. Thursday: a behind-the-scenes post about writing or ministry.

5. Friday: share a review, a reader photo or a story of impact.

6. Weekend: a direct post with the book link and one reason to read it.

Batch the week in one sitting: film three or four short videos at once, write the captions, and schedule everything. On your secondary platform, repost the best two pieces of the week. Spend ten minutes a day replying to comments and messages. Most of our authors find that this rhythm takes two to three hours a week once it is set up, which is far less than they feared.

Using reels and short video

Short vertical video is the fastest way for new readers to meet you. Reels, TikToks and YouTube Shorts are shown to people who do not follow you yet, which is exactly who a new book needs. The first two seconds decide everything, so open with the most surprising line, the hardest question or the most emotional moment, not your name or the book title. Keep most videos between 15 and 60 seconds, add captions because many people watch without sound, and end with a simple call to action. You do not need to dance or perform. Some of the best book reels are an author telling one true story, a striking sentence from the book over simple footage, or an audiogram of a page read aloud. If filming is the barrier, it can be done in a single session that feeds a month of posts. Our reels for authors service scripts, films and edits up to 20 reels a month, and it is the service that most often brings new readers to our authors.

Mistakes that waste an author's time

A few common habits cost authors months of effort with little to show for it. The first is buying followers or engagement. Jane Friedman advises against spending a marketing budget on purchased followers, and the reason is simple: they are not readers, they never buy, and they teach the platform to show your posts to the wrong people. The second is posting only announcements. A feed that says "buy my book" every day gives no one a reason to follow you. The third is spreading thin across five or six platforms and doing none of them well. The fourth is giving up after two weeks, before any platform has had time to learn who your posts are for. The fifth is sending every click to a store page with no way to stay in touch. Collect email addresses with a free chapter or a short guide, because a reader on your list is a reader you can reach on launch day, whatever the algorithm decides. Avoid these five and the time you spend on social media will keep paying back.

Measuring what actually works

Likes feel good but they do not sell books. Track four numbers instead: clicks from social media to your book or website, new email subscribers, reviews, and sales. Most platforms show which posts sent people to your link; check once a week and make more of what worked. A video that brings fifty clicks is worth more than a post with five hundred likes and no clicks. Give each experiment a fair test of four to six weeks before you judge it, because reach on new accounts builds slowly. If one platform clearly outperforms the other, move more of your time there. Write the four numbers down on the first of every month; a simple spreadsheet is enough to show whether the work is growing your readership. Finally, connect social media to something you own. An email list or a simple website keeps your readers even if an algorithm changes.
