How Authors Can Promote a Book With a Book Trailer

How Authors Can Use a Book Trailer to Promote and Market Their Book

A powerful book trailer can do something a static advertisement cannot: it can make readers feel the atmosphere, emotion, tension, and promise of a book before they turn the first page.

Much like a movie trailer, a book trailer combines images, text, music, narration, animation, and carefully selected excerpts to introduce the story and leave viewers wanting more.

Once the trailer is created, it should not be posted once and forgotten. It can become one of the most versatile pieces of content in an author’s marketing campaign.

In this step-by-step guide, MK Marketing explains how authors can use a book trailer to promote their work, where to share it, and how to repurpose it across websites, social media, email campaigns, virtual events, and reader outreach.

What Is a Book Trailer?

A book trailer is a short promotional video designed to introduce a book to potential readers.

Depending on the book and marketing strategy, it may include:

• The book cover
• A compelling opening hook
• Images inspired by the story
• Short excerpts or quotations
• Character or setting introductions
• Music and sound effects
• Author narration
• Professional voice-over narration
• Editorial reviews
• Awards or bestseller recognition
• Purchase information
• A clear call to action

A fiction trailer may focus on atmosphere, characters, conflict, and emotional stakes. A nonfiction trailer may highlight the problem the book addresses, the solution it offers, and the reader who will benefit from it.

A memoir trailer may combine personal photographs, historical details, locations, narration, and meaningful quotations from the book.

Why Should Authors Use a Book Trailer?

Online audiences are surrounded by content. A book trailer gives authors a visual way to interrupt the scroll and capture attention.

A strong book trailer can help an author:

• Introduce the book to new readers
• Communicate the genre and tone
• Create emotional interest
• Increase recognition of the book cover
• Generate content for social media
• Support a book launch
• Drive visitors to an author website
• Encourage clicks to a retailer
• Strengthen media and podcast pitches
• Promote book signings and events
• Provide bookstores and reviewers with shareable content
• Make an older book feel new again

The trailer does not need to explain the entire book. Its purpose is to create curiosity.

Step 1: Identify the Goal of the Book Trailer

Before creating or promoting a book trailer, decide what you want it to accomplish.

Possible goals include:

• Announcing a new book
• Building anticipation before publication
• Increasing preorders
• Generating sales after launch
• Introducing an author or book series
• Promoting a new edition
• Supporting a virtual book tour
• Attracting reviewers
• Reaching bookstores and libraries
• Promoting an event
• Reviving interest in a backlist title

The goal will influence the trailer’s message, length, visuals, call to action, and distribution plan.

For example, a preorder trailer should include the release date and a preorder message. A trailer promoting an already published book should direct viewers to order the book now.

Step 2: Define the Ideal Reader

A book trailer should be designed for the reader most likely to enjoy the book.

Ask:

• What genre does the reader already enjoy?
• What age group is the book written for?
• What emotions does the reader want to experience?
• What problem does the book help solve?
• What themes will attract the reader?
• Which social media platforms does the reader use?
• What other books, authors, or subjects interest this audience?

A thriller reader may respond to fast pacing, tension, shadows, urgent music, and short lines of text. A reader interested in personal development may respond to a clearly stated problem, an inspiring transformation, and a practical promise.

The trailer should match the expectations of the genre without looking identical to every other book in that category.

Step 3: Choose the Strongest Hook

The opening seconds matter.

Do not begin with a long author biography or several screens of publishing information. Start with the most intriguing reason someone should continue watching.

A hook might be:

• A provocative question
• A surprising fact
• A dangerous situation
• A powerful quotation
• A mystery
• An emotional statement
• A promise of transformation
• A character facing an impossible choice

Examples include:

• What if the person you trusted most was hiding the truth?
• One letter changed everything.
• She survived the war. Now she must survive the secret.
• Your relationship with money began long before your first paycheck.
• Some journeys take you home. Others reveal why you left.

The hook should be short enough to understand immediately.

Step 4: Write a Short Trailer Script

Most book trailers work best when they are focused and concise. A practical promotional length is approximately 30–90 seconds.

The script should not summarize every chapter or reveal the entire plot. It should create a progression that leads viewers toward the book.

A simple trailer structure is:

Opening Hook

Introduce a question, conflict, promise, or emotional statement.

Story or Subject

Provide enough information for viewers to understand the book’s central idea.

Rising Interest

Increase the tension, emotion, urgency, or benefit.

Book Reveal

Display the book cover, title, and author’s name clearly.

Call to Action

Tell viewers what to do next.

Possible calls to action include:

• Order your copy today.
• Available now.
• Preorder today.
• Read the story.
• Begin the journey.
• Visit the author’s website.
• Download the media kit.
• Request the book at your local library.
• Available wherever books are sold.

Keep text screens short. Viewers should have enough time to read each line without pausing the video.

Step 5: Create a Visual Storyboard

Before producing the trailer, plan what the viewer will see during each part of the script.

A storyboard does not need to be complicated. It can be a simple list connecting each line of the script to an image, video clip, animation, or book-cover detail.

For example:

1. Opening image and hook
2. Introduction to the setting
3. Main character or subject
4. Central conflict or problem
5. Emotional or dramatic escalation
6. Book-cover reveal
7. Review quotation or award
8. Purchase call to action
9. Author website

This helps ensure the visuals support the message instead of feeling like an unrelated collection of stock footage.

Step 6: Use High-Quality, Legally Licensed Assets

Every image, video clip, sound effect, font, and piece of music used in the trailer should be original, purchased, properly licensed, or provided with permission.

Do not download photographs, videos, or music from a search engine and assume they are free to use.

Keep copies of:

• Image licenses
• Video licenses
• Music licenses
• Font licenses
• Narration agreements
• Photographer permissions
• Model releases
• Publisher permissions
• Book-cover files
• Author photographs

Be especially careful with music. A song available inside a social media app may not be licensed for use in a paid advertisement or on another platform.

When promoting a Reel as an advertisement, Meta recommends using original audio or royalty-free music instead of licensed music from its general music library. Review Meta’s guidance for boosting Reels.

Step 7: Include the Book Cover Clearly

The book cover is one of the most important elements in the trailer.

Display it long enough for viewers to recognize:

• The title
• The author’s name
• The cover design
• The series name, when applicable

The cover should appear at least once near the end, although it may also appear briefly at the beginning.

Do not distort, stretch, recolor, crop, or redesign the cover. Use the final high-resolution cover supplied by the author or publisher.

Step 8: Add Music, Narration, and Sound Carefully

Music can shape how viewers interpret the trailer.

Choose audio that supports the book’s genre and emotional direction:

• Suspenseful music for thrillers
• Cinematic music for fantasy
• Warm acoustic music for memoir
• Playful music for children’s books
• Reflective music for poetry
• Inspiring music for personal development
• Elegant orchestral music for historical fiction

Music should support the narration and text rather than overpower them.

If the trailer includes narration:

• Use a clear, professional recording.
• Match the voice to the genre and audience.
• Remove background noise.
• Keep the narration at a consistent volume.
• Leave room for dramatic pauses.
• Avoid reading the entire book description word for word.

Sound effects should be subtle. Too many dramatic effects can make a trailer feel busy or unprofessional.

Step 9: Add Captions and On-Screen Text

Many people watch social media videos without sound. The trailer should still communicate its message when muted.

Include:

• Captions for narration
• Short on-screen hooks
• The book title
• The author’s name
• The website or purchase direction
• A final call to action

Use large, readable text with strong contrast.

Keep important text away from the extreme top, bottom, and sides of a vertical video. Social platforms may place usernames, captions, buttons, and navigation controls over those areas.

Step 10: Create Multiple Video Formats

One trailer format will not fit every platform equally well.

Consider creating:

Horizontal 16:9 Version

Best for:

• YouTube
• Author websites
• Blog posts
• Media pages
• Presentations
• Bookstore displays
• Virtual events

Vertical 9:16 Version

Best for:

• Instagram Reels
• Facebook Reels
• TikTok
• YouTube Shorts
• Instagram Stories
• Facebook Stories
• Pinterest full-screen video

Square 1:1 Version

Useful for:

• Social media feeds
• Email graphics
• Certain advertisements
• Platforms or placements where vertical video may be cropped

Do not simply crop the horizontal trailer into a vertical frame. Text, faces, book covers, and important images should be repositioned for each version.

Meta specifically recommends vertical 9:16 video with important creative elements kept inside the safe zone for Reels placements. Review Meta’s Reels advertising guidance.

Step 11: Add a Clear Call to Action

The trailer should tell viewers what to do after watching.

Choose one primary action.

Examples include:

• Visit the author’s website.
• Order the book.
• Preorder now.
• Join the email list.
• Download a free chapter.
• Attend the book signing.
• Request a review copy.
• Book the author for an interview.
• Follow the author for updates.

Avoid placing five different calls to action on the final screen. One strong direction is usually more effective.

Step 12: Create a Strong Thumbnail

A thumbnail is the still image people see before playing the video.

An effective book-trailer thumbnail may include:

• The book cover
• A dramatic visual
• A short hook
• The author’s name
• A “Book Trailer” label
• A consistent brand design

Avoid using too much text. The thumbnail should remain understandable when viewed at a small size.

Make sure the book cover is large enough to recognize and that the title is not blocked by platform controls.

Where Should Authors Post and Share a Book Trailer?

Once the trailer is complete, distribute it across multiple channels. Each location provides a different opportunity to reach readers.

1. The Author’s Website

The author website should serve as the central home for the trailer.

Embed it on:

• The home page
• The book page
• The author’s media page
• A dedicated trailer page
• A blog post announcing the book
• A virtual book-tour page
• A press or media kit page

Place a purchase button near the video so interested viewers can take the next step immediately.

Embedding the YouTube version can also reduce the amount of video data hosted directly by the website.

2. YouTube

Upload the complete horizontal trailer to the author’s YouTube channel.

Optimize the upload with:

• A searchable title
• A detailed description
• The book title
• The author’s name
• Genre keywords
• Purchase links
• The author website
• Relevant hashtags
• A custom thumbnail
• Captions
• A playlist for books or trailers

Example title:

Official Book Trailer for [Book Title] by [Author Name]

You can also upload a vertical version as a YouTube Short. YouTube classifies qualifying square or vertical videos of up to three minutes as Shorts. Review YouTube’s current Shorts guidance.

Add the full trailer to:

• The channel homepage
• A book trailer playlist
• Related author interviews
• Video descriptions
• Pinned comments
• Community posts, when available

3. Instagram

Share the vertical trailer as an Instagram Reel.

You can also use it in:

• Instagram Stories
• A launch countdown
• A pinned Reel
• An author introduction
• A carousel containing the trailer and book graphics
• Paid promotions
• Collaborative posts with publishers, bookstores, or influencers

Add a compelling caption, genre-related hashtags, and a clear direction to the link in the author’s bio.

After sharing the complete trailer, repurpose shorter moments into additional Reels. One trailer can provide several weeks of social content.

4. Facebook

Post the trailer to:

• The author’s Facebook Page
• The author’s personal profile, when appropriate
• Facebook Reels
• Facebook Stories
• Book launch event pages
• Reader communities that permit promotion
• Genre-specific groups that allow author posts
• Paid advertising campaigns

Always review group rules before sharing promotional content.

Facebook has moved video discovery into its Reels experience, so authors should make sure their video includes a clear description, appropriate visibility settings, and useful hashtags. Read Facebook’s current Reels information.

Pin the trailer or its announcement post near the top of the author’s Page during the launch period.

5. TikTok and BookTok

TikTok can be especially valuable for books with a strong emotional hook, visually recognizable genre, or active reader community.

Post the vertical trailer with:

• A short caption
• Genre keywords
• Relevant hashtags
• The book title
• A clear opening hook
• A recognizable cover image
• A call to action

Possible hashtags may include:

• #BookTok
• #AuthorTok
• #BookTrailer
• #BookRecommendation
• Genre-specific hashtags
• Theme-specific hashtags
• Reader-community hashtags

Do not rely only on broad hashtags. Combine them with specific phrases describing the book’s genre, audience, themes, or setting.

TikTok allows creators to upload an existing video and add a description, hashtags, tagged accounts, location information, links where available, and privacy settings before publishing. Review TikTok’s posting guidance.

6. Pinterest

Upload the trailer as a video Pin.

Create boards related to:

• The book
• The author
• The genre
• The setting
• Character inspiration
• Historical research
• Themes
• Reader recommendations
• Book-club selections

Include:

• A keyword-rich title
• A helpful description
• A link to the book page
• A strong cover image
• Relevant topic tags

Pinterest allows creators to upload video Pins, add titles and descriptions, select a cover, organize the content on a board, and include a destination link. View Pinterest’s video Pin instructions.

Unlike a social post that may disappear quickly in a feed, a properly optimized Pin can continue directing people to the author’s website over time.

7. LinkedIn

LinkedIn can be useful for:

• Business books
• Leadership books
• Professional development
• Memoirs
• Educational books
• Industry-specific nonfiction
• Authors who speak or consult
• Books connected to workplace issues

Share the trailer with a short post explaining why the author wrote the book, who it is intended to help, and what conversation it hopes to begin.

The trailer can also support speaking, consulting, training, and interview opportunities.

8. Email Newsletters

Send the trailer to the author’s email list.

Most email platforms do not play embedded video directly inside every inbox. A more dependable approach is to include a thumbnail image with a play button that links to:

• The author’s website
• YouTube
• A book landing page
• A retailer page with supporting information

Use the trailer in emails announcing:

• Cover reveal
• Preorders
• Publication day
• Virtual book tour
• Book signing
• Giveaway
• New edition
• Award or review
• Holiday promotion

Do not send the exact same email repeatedly. Introduce the trailer from a different angle each time.

9. Blog Posts

Create a blog post announcing the trailer.

The post can include:

• The embedded trailer
• A short introduction
• The inspiration behind the book
• A synopsis
• An excerpt
• Editorial reviews
• Purchase links
• The author biography
• Social-sharing buttons

A dedicated blog post gives the trailer a permanent page that can be shared with readers, reviewers, media professionals, and search engines.

10. Online Media Kits

Include the trailer in the author’s digital media kit.

Provide:

• The trailer link
• The embeddable YouTube link
• A downloadable thumbnail
• A short trailer description
• The book cover
• The book synopsis
• The author biography
• Purchase information
• Interview topics
• Contact information

A trailer can help journalists, bloggers, podcast hosts, bookstores, and virtual-tour participants understand the book quickly.

11. Podcast and Media Outreach

When pitching an author for an interview, include a link to the trailer when it strengthens the pitch.

Do not attach a large video file unless requested. A link to the trailer is easier for the recipient to open and share.

The trailer can give a podcast host or journalist a quick understanding of:

• The book’s topic
• The genre
• The visual identity
• The author’s positioning
• The emotional tone
• Potential interview questions

12. Virtual Book Tours

Provide the trailer to participating:

• Book bloggers
• Reviewers
• Interviewers
• Bookstagrammers
• BookTok creators
• Podcast hosts
• Online magazines
• Reader communities

Ask participants whether they can embed or share the trailer as part of:

• Author interviews
• Book spotlights
• Guest posts
• Reviews
• Giveaways
• Social media features

Create a short press description that makes the trailer easy to introduce.

13. Bookstores and Libraries

Send the trailer link to bookstores and libraries when requesting:

• A book signing
• An author talk
• A reading
• A workshop
• A community event
• A local-author feature
• Inclusion in a newsletter

The trailer may also be used on a display screen during an in-person event, with the venue’s permission.

Create a version that can play without sound because retail and library environments may keep screens muted.

14. Book Signings and Author Events

Play the trailer:

• Before the presentation begins
• During audience arrival
• At a vendor table
• On a tablet
• On a presentation screen
• During a virtual event
• As part of an author introduction

Add a QR code linking to the trailer or book page on:

• Bookmarks
• Postcards
• Table signs
• Posters
• Flyers
• Media kits
• Business cards

Always test the QR code before printing promotional materials.

15. Online Reader Communities

Share the trailer in online communities only when promotional posts are permitted.

Possible communities include:

• Genre-specific reader groups
• Book clubs
• Local author organizations
• Writing groups
• Alumni communities
• Historical societies
• Professional associations
• Topic-specific forums

Participate in the community before posting a promotion. A trailer is more likely to receive a positive response when it contributes to an existing conversation.

16. Paid Social Media Advertising

A book trailer can be used in paid campaigns on platforms such as Facebook, Instagram, YouTube, TikTok, Pinterest, and LinkedIn.

Before advertising:

• Create a shorter version.
• Place the strongest hook in the opening seconds.
• Add captions.
• Keep the book cover visible.
• Use a clear call to action.
• Create platform-specific dimensions.
• Confirm that all music is licensed for advertising.
• Track clicks and conversions.
• Test more than one opening hook.

Do not assume the full trailer will automatically make the best advertisement. A 10–30-second cut may perform better for a cold audience.

Step 13: Repurpose the Trailer Into More Content

A trailer should become a content library, not a single post.

Create:

• A 60–90-second full trailer
• A 30-second promotional cut
• A 15-second teaser
• A cover-reveal clip
• A character-focused clip
• A setting-focused clip
• A quotation clip
• A review clip
• A preorder clip
• A publication-day clip
• A book-signing clip
• A silent captioned version
• A horizontal version
• A vertical version
• A square version
• Animated GIFs
• Still images taken from the trailer
• A thumbnail with a play button

Each version can highlight a different reason to read the book.

Step 14: Create a Book-Trailer Posting Schedule

Avoid posting the trailer everywhere on the same day and then never mentioning it again.

A simple campaign might include:

Four to Six Weeks Before Release

Share a brief teaser or behind-the-scenes image.

Three Weeks Before Release

Announce that the official trailer is coming.

Two Weeks Before Release

Publish the complete trailer on the author’s website and YouTube.

One Week Before Release

Share the vertical version on Instagram, Facebook, TikTok, and Pinterest.

Publication Day

Repost the trailer with a direct purchase call to action.

Week After Release

Share a shorter version featuring a review or reader reaction.

Ongoing Promotion

Reuse trailer clips for interviews, events, book-club outreach, holidays, awards, and milestone announcements.

The same trailer can be promoted more than once, but the caption, hook, thumbnail, or call to action should change.

Step 15: Measure the Results

Track more than video views.

Review:

• Watch time
• Completion rate
• Likes
• Comments
• Shares
• Saves
• Profile visits
• Website clicks
• Email signups
• Retailer clicks
• Preorders
• Sales
• Event registrations
• Interview inquiries

Use trackable links when possible so you can identify which platform sends visitors to the book page.

If viewers stop watching during the opening seconds, test a stronger hook. If the video receives views but few clicks, improve the call to action.

Common Book-Trailer Mistakes to Avoid

Making the Trailer Too Long

A trailer should create curiosity, not explain every part of the book.

Starting Too Slowly

The strongest line or image should appear near the beginning.

Using Too Much Text

Viewers need time to read each screen.

Using Unlicensed Music or Images

Copyright problems can lead to removed videos, rejected advertisements, muted audio, or legal concerns.

Hiding the Book Cover Until the Final Second

Viewers should have enough time to recognize the cover and title.

Forgetting Captions

The trailer should still make sense without sound.

Using Only One Format

A horizontal video may not display effectively in a vertical social feed.

Posting Without a Call to Action

Tell the viewer what to do next.

Sharing the Trailer Only Once

Repurpose and redistribute it throughout the marketing campaign.

Focusing Only on Views

The real goal may be website visits, email signups, purchases, reviews, interviews, or event registrations.
