Selling books on Amazon isn’t just about hitting publish. It’s about getting noticed in a store where thousands of new titles go live every single day.
This guide breaks down how to actually get seen—through ads, search rankings, and smart visibility tactics.
Key Takeaways
- Amazon’s algorithm favors performance. Sales velocity, click-through rate, and reviews all impact your book’s visibility in search.
- Your book listing is your storefront. A strong title, keyword-rich subtitle, clean formatting, and a scroll-stopping cover all work together to convert browsers into buyers.
- Amazon ads work—but only with strategy. Start small with manual campaigns, monitor your metrics, and optimize slowly to avoid wasting money.
- Early reviews build trust. Aim for 3–5 in your launch week, using ethical, allowed methods like ARC readers and email list outreach.
- Sales momentum beats sales spikes. Spread out promotions, use KDP Select tools wisely, and focus on consistency, not one-time boosts.
- External traffic matters. Amazon rewards books that bring in outside buyers, so use your blog, social channels, and email list to send engaged readers directly to your page.
- You don’t have to figure it all out alone. Trelexa helps authors like you fine-tune listings, run smart ads, and create visibility that lasts.
Understanding the Amazon Bookstore Algorithm
Before you run ads or promote your book, you need to know how Amazon decides which books to show first. Its recommendation system isn’t random—it’s based on specific signals that reward relevance, quality, and performance. When you know what those signals are, you can work them in your favor.
How the A9 algorithm works for books
Amazon’s algorithm (A9) is designed to help readers find what they’re most likely to buy. Unlike Google, it’s not trying to provide the most informational result—it’s trying to generate a sale.
Here’s what A9 pays attention to when ranking books:
- Sales history: Books with a consistent sales pattern are more likely to rank.
- Keyword match: Titles, subtitles, and metadata that match the search term have an advantage.
- Conversion rate: If your page converts well (meaning people buy it after landing), you’ll be favored.
- Review quantity and quality: A higher number of recent, positive reviews increases trust.
- Click-through rate: If your book gets clicked more often than others in search results, that sends a signal.
Amazon rewards books that look like they’re going to sell. Your job is to give the algorithm proof that yours will.
Why categories and subcategories can make or break you
Choosing the right categories can be the difference between being buried and being a bestseller. It’s not about picking the most popular genre—it’s about selecting one where your book has room to win.
Here’s how to approach it:
- Aim for specific over broad. Instead of “Self-Help,” aim for “Personal Transformation” or “Time Management.”
- Check competition. Look at the top books in each category. If they all have thousands of reviews, pick another.
- Use all your category slots. Amazon only shows three, but you can request more through Author Central.
Being in the right niche can help you earn a bestseller tag faster—and that tag feeds your visibility even more.
How Amazon treats new books vs. older titles
New releases get a temporary advantage known as the “honeymoon period.” This is when Amazon is watching closely to see how your book performs with early traffic.
To make the most of it:
- Plan your launch activities around your first 30 days. That’s when you’ll get the biggest lift.
- Drive consistent sales early on. Don’t aim for one big spike—aim for steady performance over the first few weeks.
- Ask for reviews right away. Early reviews help Amazon build confidence in your listing.
Older books can still perform well, but without that early push, they’ll need ongoing marketing to regain momentum.
Optimizing Your Amazon Book Listing for Maximum Visibility
Your book listing isn’t just a product page—it’s your sales page, SEO foundation, and credibility check all in one. If any part of it feels weak or rushed, your visibility and conversion rate will suffer. Every element, from the title to the description to the cover, plays a role in whether readers find your book and feel confident buying it.
Writing a compelling title and subtitle
Your title needs to hook, but your subtitle needs to do the heavy lifting. Together, they should make the reader stop scrolling—and tell Amazon exactly what your book is about.
Here’s how to strike that balance:
- Make the title readable first. Don’t stuff keywords into the main title. Keep it clean and easy to remember.
- Use the subtitle for keywords. This is where you can be more descriptive and include search terms people are typing.
- Keep it mobile-friendly. On smaller screens, long subtitles get cut off. Put the most important words first.
Avoid gimmicky punctuation and formatting tricks. Clear, honest titles that match search intent will perform better every time.
The power of book descriptions (and HTML formatting tips)
Your description is the one place you can sell your book with full sentences—but formatting matters just as much as content. Big blocks of text will lose readers fast.
Structure your description like this:
- Start with a bold hook (a question, a strong statement, or a pain point).
- Follow with a short paragraph that expands on what the book solves or delivers.
- Use bullet points to break down key benefits or takeaways.
- Close with a call to action. Invite the reader to scroll back up and click “Buy Now.”
Amazon supports limited HTML. Use <b> for bold, <br> for spacing, and avoid unsupported tags like <h1> or <img>. When done well, formatting makes your listing skimmable, professional, and persuasive.
Choosing the right keywords
Amazon gives you a backend keyword section where you can enter terms that help your book surface in search results—even if those words don’t appear in your title or description.
Here’s how to get the most out of it:
- Research what readers are searching. Start typing in Amazon’s search bar and note the autocomplete suggestions.
- Use keyword tools. Publisher Rocket, KDP Wizard, and Google Trends can uncover high-volume, low-competition terms.
- Avoid repetition. If you’ve already used a keyword in your title or subtitle, no need to repeat it in the backend.
Instead of guessing what people are typing, look for patterns. Your goal is to speak Amazon’s language behind the scenes while staying reader-friendly on the surface.
Cover design that stops the scroll
Covers are the first impression. If yours doesn’t look professional, genre-appropriate, and eye-catching as a thumbnail, most people won’t even read your title.
What works well for Amazon covers:
- Simple, high-contrast design. Avoid clutter and tiny fonts that won’t show up in thumbnail size.
- Clear genre cues. A sci-fi book should look sci-fi. A business book should look like it belongs in the business category.
- Professional typography. Font choice says a lot. Amateur fonts scream self-published. Clean, modern fonts suggest quality.
This isn’t the place to cut corners. A good cover designer with Amazon experience is worth every dollar.
Running Amazon Ads Without Wasting Your Budget
Running ads on Amazon sounds easy—until you wake up to a drained budget and zero sales. The truth? Most authors lose money on ads because they set them up with guesswork instead of a clear strategy. When done right, Amazon ads can drive visibility and build momentum. When done wrong, they burn cash with nothing to show for it.
Understanding the types of Amazon ads for books
Amazon offers multiple ad formats, but not all of them make sense for first-time authors. Here’s what you need to know before turning anything on.
- Sponsored Products: These are the most common and beginner-friendly. They show your book in search results or on competitor pages.
- Sponsored Brands: Better for authors with a catalog. These display your author name and multiple books in a banner format.
- Lockscreen Ads (Kindle only): These ads show up on Kindle devices. They’re great for genre fiction, but require a higher daily budget.
Start with Sponsored Products. They’re targeted, flexible, and easier to control. Once you have data, you can expand.
Setting up your first ad campaign the right way
The setup matters. A lazy or broad campaign will spend your money fast without giving you useful data.
Instead, build it this way:
- Use manual targeting, not automatic. Automatic ads cast too wide a net. Manual gives you more control over keywords and bids.
- Start with a small budget. $5–$10 per day is enough to collect data without overcommitting.
- Group keywords by theme. Don’t lump 100 random keywords into one campaign. Group by relevance (e.g., topic, reader intent).
- Bid conservatively. Don’t be fooled by high suggested bids. Start low and raise only if the clicks are quality.
Give your ad 5–7 days before making changes. Let Amazon gather data before you panic about performance.
Tracking ROI and optimizing campaigns
Ad results can feel like a black box if you don’t know what to look for. Good decisions come from reading the right metrics.
Here are the key ones:
- ACOS (Advertising Cost of Sale): The lower, the better. Anything under 70% is a good start for most authors.
- CTR (Click-Through Rate): If people aren’t clicking, your cover/title combo may need work—or your keywords are off.
- Impressions: High impressions with no clicks means your listing isn’t compelling enough in search.
Once you spot a pattern—positive or negative—adjust accordingly. Pause underperforming keywords, add new ones from customer search term reports, and gradually scale the winners.
Common Amazon ad mistakes that kill sales
Sometimes it’s not your book—it’s your ad strategy. Here are the most common missteps that quietly wreck campaigns:
- Overbidding too early. Big bids don’t guarantee good placements. They just burn your money faster.
- Targeting irrelevant keywords. “Bestseller” or “book club” might sound appealing, but they rarely convert.
- Running one giant ad group. If you can’t tell which keyword is doing what, you can’t improve anything.
- Turning off ads too soon. Give campaigns time to learn. Don’t judge after 48 hours.
Treat your ads like a garden. Water them, check the soil, prune the weak spots. Don’t just set it and hope.
Getting Reviews Ethically (And Why They Matter So Much)
A book without reviews looks untested. On Amazon, that’s the same as invisible. Readers rely on reviews as social proof, and the algorithm uses them as a ranking factor. But you can’t game the system. You need to earn reviews the right way—ethically, consistently, and without violating Amazon’s rules.
How many reviews do you need to gain traction?
You don’t need hundreds of reviews to start seeing movement. You just need enough to create trust.
Here’s a general baseline:
- 3–5 reviews: Minimum to look credible on launch week
- 10–15 reviews: Enough to support basic ad campaigns
- 25+ reviews: Often the threshold for triggering better conversions and higher ad performance
The goal isn’t just quantity. It’s timing. Getting your first handful of reviews quickly—within days of launch—tells Amazon your book is active and worth showing to others.
Review strategies that don’t break Amazon’s rules
Amazon has cracked down on fake reviews and biased requests. But there are still safe, reliable ways to ask for real feedback.
Here’s what you can do:
- Send advance copies to a small reader group. These can be beta readers or early supporters. Let them know the review is optional and must be honest.
- Use your email list. Ask readers who’ve bought or read the book to leave a review. Avoid offering anything in return.
- Follow up post-purchase. If you’re using KDP, Amazon may send follow-up emails, but you can also direct readers via your website or socials.
What to avoid:
- Asking family or close friends
- Offering incentives or gifts
- Phrasing that implies a positive review is expected
Keep your ask simple, respectful, and non-pushy. People are more willing to help than you think—especially if the book left a mark.
The long-tail value of reviews
Reviews aren’t just for launch week. They work for you long after the campaign ends.
Here’s how:
- Better ad conversion: A well-reviewed book makes ad clicks more likely to turn into sales.
- Higher search ranking: Amazon favors books with consistent, quality reviews over time.
- Reader trust: Even three years later, a new reader scanning your page will look for confirmation that the book delivers.
One honest review from a reader who gets your book is more powerful than ten generic blurbs. Focus on building a base of reviews that reflect your message and genre. Those are the ones that will keep working in your favor long after the initial launch noise fades.
Ranking Higher in Amazon Search Without Ads
You don’t need a big ad budget to move up Amazon’s search results. Organic visibility comes from momentum—when your book consistently attracts clicks, sales, and positive signals. The good news? You can create that momentum with smart timing, outside traffic, and the tools Amazon already gives you.
The role of sales velocity
Sales velocity isn’t about how many books you sell overall—it’s about how often you’re selling. A steady drip of purchases over several days or weeks often ranks better than a one-day spike followed by silence.
To improve your sales velocity:
- Space out your promotions instead of stacking them on one day
- Offer limited-time discounts to prompt faster decisions
- Sync any social or newsletter pushes to maintain daily sales flow
Amazon’s algorithm rewards consistency. Even selling 3–5 copies a day for a week can push your book up the ranks more than a single burst of 100 sales.
Using promotions and free days strategically
KDP Select comes with perks—if you know when and how to use them. You can run up to five free days or a Kindle Countdown Deal every 90 days, and both can increase discoverability fast.
When to use them:
- Free days: Great for building your review base, especially early on
- Countdown deals: Ideal for driving paid sales during a short window
- Book promo sites: Tie these into your promos (e.g., Freebooksy, BookSends, EReader News Today)
Timing matters. Launch a promo when your listing is solid—cover, keywords, and reviews in place—so that any spike in traffic actually converts into long-term visibility.
Driving external traffic (and why Amazon loves it)
Amazon tracks where traffic comes from—and when you bring in outside clicks that convert, it’s a signal of quality. In short, if you can send readers to Amazon who end up buying, you’ll be rewarded.
Here are a few ways to do that:
- Email your list. Even a small audience can generate sales if it’s targeted and engaged.
- Use social posts with direct Amazon links. Especially on launch week, when those sales matter most.
- Write blog posts or articles related to your book. Use them to funnel readers to your Amazon listing.
- Set up newsletter swaps with other authors. Cross-promote with others in your genre.
Every external click that results in a purchase or Kindle read tells Amazon: this book is worth pushing higher. And the best part? These readers often convert better, because they’re coming from a place of trust—not just a random search.
