Book Advertising: How to Run Facebook and Google Ads That Sell Books (2026 Guide)

book advertising, facebook ads, google ads

Updated for 2026. Originally published 2026 – advertising has changed, but the principles are the same: your cover and book description sell the book; the ads just find the right readers.

Book advertising in 2026: the short version

In 2026, most indie authors should split their ad budget three ways: Amazon Ads (highest intent – readers already buying), Facebook/Meta Ads (best for discovery and visual genres), and BookBub Featured Deals (best for discounted launches). Google Ads are rarely worth it for individual books – their keyword CPCs are too high vs. the royalty you earn. Start with Amazon Ads first ($5-10/day), Facebook second ($5-10/day once you have reviews), then layer BookBub if you run discounted promos.

Advertising for a book: what actually works in 2026

The three ad channels that still convert for indie authors:

Amazon Ads (Sponsored Products + Brand Ads) – target competitor ASINs, category keywords, and author-name keywords. Cheapest intent on the internet for books because the clicker is already shopping on Amazon.
Facebook/Meta Ads – use video or carousel creative showing the cover + blurb + reviews. Target lookalike audiences built from your email list or pixel data. Retarget anyone who visited your Amazon page.
BookBub Featured Deals – premium placement to BookBub’s opted-in reader list. Expensive ($200-$2000) but can generate thousands of downloads/sales in one day during a 99c or free promo.

Facebook Ads for book marketing (targeting, creative, budget)

Targeting: Start with author/series lookalikes rather than broad interest targeting. Facebook’s interest-based targeting for “people who like Stephen King” is noisy. Build a lookalike from your email list (if 1000+ contacts) or from website visitors (if you have the Facebook pixel running).

Creative: Video beats static for most genres. Show the cover in motion (4-6 seconds), then a 2-3 sentence hook from your back cover blurb, then a CTA. If you can’t do video, use a carousel with 3-5 images showing cover + quotes from reviews.

Budget: Start at $5-10/day for 2 weeks to let Facebook’s algorithm learn. If ROAS (return on ad spend) is above 1.2x – scale up. If below 1.0 – kill the campaign and try new creative or targeting.

Amazon Ads for authors (the highest-intent channel)

Amazon Ads for books is the closest thing to free money in publishing marketing – if you set it up right:

Log into advertising.amazon.com with your KDP account.
Create a Sponsored Products campaign. Use manual keyword targeting, not auto.
Seed 50-100 keywords: competitor author names in your genre, category terms (“epic fantasy new release”), and your own book title.
Set bids low: $0.25-$0.50/click. You’ll lose some auctions but your ROAS will be strong on the wins.
Let it run for 2 weeks. Pause any keyword with 30+ clicks and no sales. Scale up the profitable ones.

Book advertising budget (how much should you spend)

Rule of thumb: your ad spend ceiling = your royalty per sale. If you earn $3.50 per book sold (70% royalty on $4.99), you can spend up to $3.50 per sale and still break even. Most indie authors aim for ROAS of 1.3-1.5 on the first book in a series, because they make their money on the read-through to books 2, 3, 4 (where marketing is organic).

Practical budgets:

Testing phase (weeks 1-2): $10-20/day across 2-3 campaigns. Expect to lose money while you learn what works.
Scaling phase (after finding a winner): $30-100/day on the winning campaign. Keep ROAS above 1.0.
Mature phase: $100-500/day if you have a full series to read-through. The math works because book 2-6 earn without marketing.

Common book advertising mistakes (and how to fix them)

Running ads before your book is review-ready. An ad that sends clicks to an Amazon page with zero reviews and a bad cover will burn money. Get 10+ reviews and a strong cover FIRST.
Bidding too high on Amazon Ads. Start low, raise when you see profitable keywords. Don’t let Amazon’s “suggested bid” pull you above royalty math.
Targeting too broad on Facebook. “Romance readers” is 500 million people. “Lookalike of my email list” is 1-2 million. Narrower beats broader every time.
No landing page. Always send ad traffic somewhere you control – your author website, Amazon page, or BookFunnel giveaway. Never send to a dead link.
Running ads on one book and expecting income. Ads work when you have a series (book 1 ad -> organic read-through to books 2-5). Single standalone books rarely pay off.

When to use Google Ads for books (usually don’t)

Google Ads for individual books almost never works in 2026. CPCs for book-related keywords are $2-5+, royalty is $2-4, math doesn’t work. The exceptions:

Non-fiction with a course/service funnel behind the book (you’re not breaking even on book sales, you’re generating leads)
High-price box sets or premium editions ($20+)
Audiobooks with retargeting (YouTube pre-roll is cheaper than search)

FAQ: Book advertising

How much does it cost to advertise a book? Most indie authors spend $50-500/month on ads once they have a series. Starting out, $10-20/day for 2 weeks is enough to learn what works before scaling.

Where should I advertise my book first? Amazon Ads. The clicker is already a book-buyer on Amazon, so the intent match is higher than any other channel.

Do Facebook Ads still work for authors in 2026? Yes, but you need strong creative (video or carousel) and lookalike targeting, not broad interest targeting.

What’s the best ad budget for a new author? $10-20/day across Amazon + Facebook for 2 weeks of testing. Expect to lose money while learning. Scale only the winning campaigns.

Book marketing is hard work, and this is why: when you talk about your book on social media, tell people to go buy it or support you, it’s annoying and spammy. These days you need to be more subtle, with content marketing and indirect ways to catch readers’ attention.

Unless you advertise: it’s fine to be promotional and direct in advertising.

And advertising is very powerful, in that you can target specific groups of people, or people already searching for certain keywords. But you can also waste a lot of money without selling any books.

So here’s a long-ish guide to advertising your book, what to avoid and watch out for, how to stay in the green and avoid advertising failure.

#1. Look Good and Be Awesome

The first rule of advertising = have a super cover design, nice 3D graphics and promotional images, and a stellar author website or landing page. Also make sure, if you’re using graphics, that they look good.

What if you don’t know how good your stuff looks?

There are ways to test: try running a text only ad, and then some ads with your book cover or images. Do more people click on the text than the image ads? Then your graphics aren’t good enough. Excellent graphics should always perform better than text only ads; if they don’t, just stick with text only ads – although if you have a bad cover, that’s going to kill sales anyway.

You can also send people directly to your website, and directly to Amazon.

If your website looks great and is amazing, it might “warm up” buyers, who will then buy the book on Amazon. But if it doesn’t, you’ll see more sales sending them straight to Amazon.

UNLESS you don’t have any reviews, have a poorly written book description, or an ugly cover. If people are clicking on your ad but not buying the book, it means your book or ad or topic is interesting enough, but you lose them on the sales page (probably because of poor design or lack of reviews).

#2. Know your readers

You need to know who your readers are and where to find them. Don’t just buy ads on any website promising book marketing or advertising (most of those sites are built for authors, you won’t see any readers there). You need to find the sites where YOUR readers hang out – we’re making that easy with our genre-specific book marketing resource pages.

Look at those sites, evaluate how much traffic they get, check out whether they offer advertising and how much it costs. There’s a video down below that talks more about that. You can also find the with BlogAds but it’s usually cheaper to go direct.

If they have advertising but it’s Google Ads, you can actually use Google Ads and set it up to just display on certain sites – sometimes you can do this and pay for less to get on sites that try to charge you much more.

#3. Hook and sell

You need to capture attention – that’s easier with a good offer. Maybe your book is discounted, today only, for 99 cents. Maybe it’s free. Scarcity and a good deal can work wonders… but it probably isn’t enough. People don’t buy books because they are cheap. They won’t to know what the book is about, the genre or topic, and whether it’s any good. You’ll have to convey all of that, really quickly, usually with a great cover and a tagline or blurb by someone. You usually don’t have much space so you need to be as impactful and concise as possible: just get them to click.

After they click, you need to fulfill. Why did they click? What did you promise? Do they get it after the click?

If you’re paying for clicks, you may be hoping to drive sales – but it’s hard to be cost effective this way, as you’ll probably get a lot of people who click but don’t buy.

It may be a better strategy to focus on building your list first, by offering a free book, or for non-fiction a great free resource. People will click to get the resource and sign up to your list; then you can use an autoresponder to share value and get them used to you, before finally asking them if they want to buy the book, after you’ve sent a few emails.
