For years, I believed BookBub Ads were only for discounted books. Every case study, every success story, every example I saw featured $0.99 books. Authors would drop their price, run a BookBub Ad, and watch the sales roll in.
But not every author wants to discount. So over the past few months, I started testing. What if BookBub Ads could work for full-price books? Turns out, they can. And better than I expected.
I’ve been running campaigns for $2.99, $3.99, and $4.99 books, while also helping other authors test full-price promotions at similar price points. We’ve seen consistent daily sales, improved Amazon rankings, and sustainable ad economics. Here’s how we do it.
Why Full-Price Book Ads Work (When Done Right)
BookBub subscribers are usually expecting deals, so why would they click on a full-price ad?
Two reasons:
First, BookBub’s audience is 100% readers. Unlike Facebook Ads, where you’re interrupting someone’s scroll through vacation photos and cat videos, BookBub subscribers are actively looking for their next book. They’ve chosen to receive emails about books in genres they love. That intent changes everything.
Second, price resistance decreases when you target the right readers. When you nail the author comp and your pitch resonates with your target audience, they care less about saving a dollar. They care about finding their next favorite book.
The key is treating BookBub Ads as one layer in a diversified marketing strategy, not your only play.
My Framework for Full-Price BookBub Ads
Start with Focused Targeting
Most authors make their targeting too broad. They select “Fantasy” or “Romance” or authors with 200k followers and wonder why their cost-per-click skyrockets and conversions tank.
I do the opposite. I target one author at a time, and choose authors with 10k–30k followers (though I will go outside of this range from time to time).
Pick a comparable author whose readers would genuinely love your book. Not just the same genre. Not just similar vibes. I mean someone whose fans would actively thank you for the recommendation.
Use CPC Bidding for Control and Predictability
I exclusively use CPC (cost-per-click) bidding for all my campaigns.
Here’s why: CPC bidding gives you much more control over your costs than CPM (cost-per-thousand-impressions) bidding. With CPC bidding, you get exposure (impressions) of your ads for free, and only pay when someone clicks.
If you’re happy to pay up to $0.75 per click, and you know it takes approximately 10 clicks to make a sale (10% conversion rate), that works out at a cost-per-sale of $7.50. So, your bid would be $0.75, but you’ll likely end up paying less.
I typically start bids around $0.80 and let BookBub’s system adjust from there. Sometimes I end up paying $0.35–$0.45 per click. Other times it settles around $0.50–$0.60. It depends on the author comp, competition, audience size, and the quality and messaging of your image.
Sometimes, $0.80 isn’t high enough and I’ll need to go up to $0.90–$1.00+ to get any traction.
The beauty of CPC is predictability. I know my cost per click, I can track my conversion rate, and I can calculate my cost-per-sale. That’s the data I need to make informed decisions.
Craft Ad Creative That Converts
Your ad creative makes or breaks full-price campaigns. I’ll take one of two approaches:
Option 1: Call readers out directly in the ad copy.
“For readers who loved [Author Name]…”
“If you devoured [Author Name]’s latest, you’ll love this…”
Editor’s Note: When referencing comparable authors in your ad image, please make sure it is clear that you are not promoting a book by that author. We reserve the right to deactivate any ads that our readers report as misleading or confusing (review our advertising policies).
This immediately filters out readers who aren’t interested, saving you money on wasted clicks. And it creates curiosity for readers who are fans of that author.
Option 2: Appeal to core reader desires.
Understanding what your readers crave is critical. Some examples:
- Romance: “Second-chance love worth fighting for” or “Enemies-to-lovers with sizzling tension”
- Thriller: “A psychological game with deadly stakes” or “One woman’s dangerous hunt for truth”
- Fantasy: “Revenge quest in a magical world” or “Forbidden love between warrior and enemy”
- Business/Marketing: “Build a six-figure business without burnout” or “Turn your expertise into scalable income”
- Self-Help: “Break free from patterns holding you back” or “Daily habits that transform anxiety into clarity”
- History: “Women who shaped the American Revolution” or “One decision that changed World War II”
Even something as simple as starting a new series. As humans, we love “new.”
You can also combine a tagline with reader reviews for social proof:
The key is specificity. Generic pitches get ignored. Specific promises that align with your readers and what they desperately want? Those get clicks.
Bonus tip: Call out Kindle Unlimited availability
If your books are in Kindle Unlimited (KU), add a reference to it in the image. It only needs to be subtle, but visible enough for people to see on their phone (where most readers will see your ads).
Try Showing the Price in Your Ad
Yes, a $4.99 book converts lower than a $0.99 book. But here’s what most authors miss: Conversion rate isn’t the only metric that matters. Cost-per-sale matters too, as does ROAS (return on ad spend).
In some cases, I’d rather have a lower conversion rate on a higher-priced book. As an example comparison:
$0.99 book (35% royalty plan):
$0.30 per click × 15% conversion = $2 cost-per-sale
Profit: $0.35 (35% of $0.99 — no delivery fee on 35% royalty plan)
$4.99 book (70% royalty plan):
$0.40 per click × 10% conversion = $4 cost-per-sale
Profit: $3.50 (70% of $4.99 minus $0.06 delivery fee)
The higher-priced book earns 10x more profit despite the lower conversion rate and higher cost-per-sale.
And here’s where it gets even better: If you’re advertising the first book in a series, you don’t need to profit on book one. Strong readthrough to books two, three, and four means you can afford to lose money — or break even — on that first sale. You’re not just buying a single book sale. You’re buying a reader into your entire catalog.
The sweet spot for full-price books seems to be $2.99–$4.99. Below that, you’re competing with discounted titles. Above that, you need exceptionally strong targeting and social proof.
All that said, there are plenty of BookBub readers happy to pay full price for the right book. It’s worth testing adding your price point to the image.
Mentioning price filters out readers unwilling to buy at that price, leading to clicks from more qualified “leads.” Yes, you’ll receive fewer clicks and a lower CTR (click-through rate) — but the clicks you get will be more likely to convert into sales, reducing wasted ad spend.
But test images without the price, too. Some campaigns perform better without it.
Layer BookBub Ads into Your Advertising Mix
BookBub Ads aren’t a replacement for Amazon Ads or Facebook Ads. They’re a valuable addition that fills gaps when other platforms have an “off day.”
- Amazon Ads performing well? Add BookBub Ads on top to bring in off-Amazon traffic and boost your sales velocity.
- Facebook Ads delivering consistent results? Layer in BookBub Ads to tap into a 100% reader audience that Facebook can’t match.
- Having a rough week where both Amazon and Facebook are underperforming? BookBub Ads can pick up the slack and keep sales flowing.
The best part? When you run multiple ad platforms simultaneously, they compound each other. More sales from BookBub Ads improve your Amazon ranking, which feeds more organic sales, which tells Amazon’s algorithm your book is worth promoting.
I wanted a clean test to see the impact BookBub Ads alone could have on a full-price book. The ads are converting at around 8% (meaning every 100 clicks turn into eight sales). This ranking boost brought organic sales that wouldn’t have happened otherwise. The ad spend paid for itself, and the ranking gains were pure upside.
As another example, let’s say you’re selling a $4.99 historical fiction novel and averaging three to five sales per day with BookBub Ads. That’s 90–150 sales per month at full price — sustainable income while you write your next book. Factor in 35–40% readthrough to books two, three, and four at full price, and suddenly you’re looking at meaningful revenue from a single ad campaign running in the background.
Or imagine a $2.99 cozy mystery targeting fans of three comparable authors, generating 8–12 sales daily. The real profit isn’t just in those book one sales — it’s in the readers who buy the entire series. That’s where the economics shift from “breaking even” to “actually profitable.”
These aren’t viral launches or chart-topping bestsellers. They’re steady, sustainable campaigns that compound over time as new readers discover your series.
Manage Your Budgets for Sustainable Growth
Start conservatively. Set daily budgets at $2–$3 while you gather data. Test multiple author comps. Try different images. Let the campaign run for at least a week before making major decisions.
Once you find a winning combination, scale gradually. Bump your budget by 30–50% at a time and monitor how the metrics change. Some campaigns can scale to $15–$20+ per day profitably. Others tap out at $5 in daily spend.
The biggest mistake I see with full-price book ads is not thinking about the bigger picture. You can’t just look at the cost-per-sale on book one and decide if a campaign is working. You need to factor in readthrough. If you’re spending to break even — or even losing a little — on book one, but 50% of readers buy book two and 30% buy the whole series, suddenly those economics look very different.
Know your numbers. Protect your margins. And always, always account for series readthrough.
Most Importantly: Track the Metrics That Actually Matter
Most authors obsess over the wrong numbers. They panic when their cost-per-click rises or celebrate when their click-through rate improves. But here’s the truth: Those are secondary metrics.
Your primary metrics are:
For standalone books:
- Conversion rate (what percentage of clicks turn into sales)
- Cost-per-sale (how much you’re paying for each sale)
For series:
- ROAS (return on ad spend)
These numbers tell you whether a campaign is profitable. Everything else — CPC, CTR, CPM — is diagnostic. These metrics help you understand why a campaign is performing a certain way, but they don’t tell you whether to keep it running or turn it off.
How I Track BookBub Ads
All the books I advertise with BookBub Ads are published on Amazon, and I use Amazon Attribution (a free tool provided by Amazon) to track the performance of my BookBub Ads. Every BookBub Ads campaign has its own unique Amazon Attribution tracking link. I can then see exactly how many sales and/or Kindle Unlimited page reads each individual BookBub Ad is generating.
From there, I can calculate the conversion rate and cost-per-sale for standalone books, and the ROAS when advertising a series.
Important note: Unfortunately, other retailers (Kobo, Barnes & Noble, Apple Books, etc.) don’t yet have tracking available, so there’s no clear-cut way to know which BookBub Ads are driving sales on these platforms. However, you can estimate performance by applying your Amazon conversion rate. If your Amazon ads convert at 10%, assume roughly 10% for other retailers to establish a baseline ROAS.
Here’s a screenshot of the tracking tool I’ve built to understand how each ad is performing:
The biggest benefit of tracking your BookBub Ads this way is that you’re getting a true picture of which ads are driving sales and which ads aren’t. And you’re not relying on the metrics in the BookBub Ads dashboard to make decisions.
Why Secondary Metrics Can Be Misleading
Here’s why you can’t rely on CTR and CPC alone:
Campaign A has a 4.5% CTR, a $0.30 CPC, and a 5% conversion rate ($6 cost-per-sale)
Campaign B has a 0.25% CTR, a $0.72 CPC, and a 12% conversion rate ($6 cost-per-sale)
They deliver the same cost-per-sale. Yet Campaign A had a “great” 4.5% CTR while Campaign B had a “terrible” 0.25% CTR. Campaign B costs more per click but delivers the same results — this is why CTR doesn’t tell the whole story.
I’ve had ads with a 0.49% CTR — which by most accounts would be considered terrible — convert at 14.29% with a low cost-per-sale of $3.94.
Bottom line: CTR is helpful context, but it’s not a leading metric. Focus on conversion rate, cost-per-sale, and ROAS. Let everything else inform your decisions, not make them.
Quick-Reference Guide: Key Takeaways
Get started right:
- Start with $2–$3 daily budgets and single-author targeting
- Set CPC bids around $0.80 initially
- Run tests for 5–7 days before making decisions
- Target authors with 10k–30k followers for best results
Create ads that convert:
- Use specific, desire-driven copy over generic pitches
- Test calling out comparable authors directly
- Consider showing the price for higher-quality leads
- Add a KU logo if your book is in Kindle Unlimited
Think like a business owner:
- You’re buying readers, not just book sales
- Sometimes a lower conversion rate beats a higher conversion rate on a higher-priced book
- Allow time for readthrough to show in your data (readers need time to finish books)
- It’s fine to break even on book one if series readthrough is strong
Track what matters:
- Primary metrics: Conversion rate, cost-per-sale, ROAS
- Secondary metrics: CPC, CTR, CPM (diagnostic only)
- Use Amazon Attribution for accurate tracking
- A “bad” CTR can still mean a profitable campaign
Scale sustainably:
- Layer BookBub Ads with Amazon Ads and Facebook Ads for compounding results
- Increase budgets by 30–50% at a time when scaling
- The sweet spot for full-price books is $2.99–$4.99
- Expect 8–17% conversion rates (one sale per 6–12 clicks) with tight targeting
Moving Forward
Full-price BookBub Ads require precision. You can’t spray and pray. You need focused targeting, sharper copy, and tighter budget management. But when you get it right, in my experience, the economics and strategy are more sustainable.
As I continue testing and helping other authors run these campaigns, I’m exploring new genres, refining targeting strategies, and looking at how BookBub Ads fit into an author’s longer-term marketing plans. The goal isn’t to replace discounted promotions, it’s to give authors another option — one that layers beautifully with other advertising platforms to create a diversified marketing engine.
You might be surprised at how well full-price books can perform when the targeting is right and the audience is hungry for their next great read.
