Do Book Trailers Actually Help Sell Books?

Do book trailers sell books? Sometimes they help, but there is little reliable public evidence that a trailer on its own drives sales. A trailer is best thought of as a tool for awareness and mood: a way to show readers what your book feels like in a few seconds. Whether it leads to sales depends on where it is shared, who sees it and what happens after they watch. It is worth separating views and engagement from actual sales when you judge one.
Key takeaways
- A trailer's main job is to create interest, not to close a sale.
- Short, vertical clips built for social platforms are often more useful than long cinematic trailers.
- Measure clicks and signups, not just views.
- For many authors, other assets, like quote graphics or a strong cover reveal, may do more for less money.
What is a trailer meant to achieve?
A book trailer can:
- Show the genre, mood and tone quickly.
- Highlight tropes and hooks.
- Give readers something shareable.
- Add polish to a launch or cover reveal.
- Create content for ads.
It cannot replace a strong cover, a compelling description and good reviews. Those are what convert interest into sales on a book page.
What kinds of trailers are there?
- Cinematic trailers: longer, produced videos, often with footage, music and narration. Costly and time-consuming.
- Short social clips: 10 to 30 seconds, vertical, often using text over mood footage or illustration.
- Animated covers: subtle motion on the cover art.
- Author-filmed videos: you talking about the book, which often feels more personal.
Where should it be shared?
- Short-video platforms and social feeds, cut to each platform's preferred length and format.
- Your website and book page.
- Your newsletter, as a link or GIF preview.
- Ads, if you are running paid promotion.
- Events and virtual launches.
A trailer sitting only on a video channel with few subscribers is unlikely to reach many readers. Plan distribution before you make it.
What does success look like?
Decide what you want the trailer to do, then measure that:
| Goal | What to measure |
|---|---|
| Awareness | Views, reach, shares |
| Interest | Profile visits, saves, comments from likely readers |
| Action | Link clicks, newsletter signups, preorders |
| Sales | Sales on days it was shared, tracked links if your platform supports them |
Be careful with attribution. A sales bump after posting a trailer might come from the trailer, or from a newsletter you sent the same day, or a review that went live. Track dates and use separate links where you can.
When might another asset be more useful?
- On a small budget: a well-designed cover reveal, quote graphics or a short self-filmed video may do more for less.
- For text-loving audiences: excerpts and newsletter content can be more effective.
- For trope-driven genres: simple trope lists and aesthetic posts often perform well.
- Before the cover is finished: wait. A trailer usually needs the final cover.
Jane Friedman emphasizes that marketing works best when it is matched to where your readers are and what you can sustain (Friedman, 2018). A trailer is one option, not a requirement.
What makes a trailer good?
- A hook in the first two seconds.
- Clear genre and mood.
- Short text that is readable without sound.
- Your cover shown clearly at the end.
- A simple call to action, like "Out March 10" or "Preorder now."
- Properly licensed music, footage and fonts.
