Facebook Ads vs Amazon Ads for Ebooks: Which Converts Better?
Quick Answer: Amazon Ads typically convert better for direct ebook sales because readers are already on Amazon with a payment method, actively browsing for books. Facebook Ads work better for email list building and for promoting free or heavily discounted ebooks. Most successful indie authors use Amazon Ads as their primary paid channel and Facebook Ads as a supplementary tool for specific goals.
The conversion difference comes down to intent. Amazon shoppers are in buying mode. Facebook users are in scrolling mode. Moving someone from scrolling to buying requires more friction (leaving Facebook, opening Amazon, finding the book, purchasing) than showing an ad to someone already searching for their next read.

When to Use Each
Use Amazon Ads for your everyday, always-on advertising. They reach readers at the point of purchase and provide clear attribution data. Start here.
Use Facebook Ads for launch-week traffic boosts (driving concentrated visits to your Amazon listing), email list building (sending traffic to your reader magnet sign-up page, where attribution is trackable), and discounted promotions (where the low price reduces the barrier to a cold-traffic impulse buy).
Bottom Line
Start with Amazon Ads. Add Facebook Ads when you have a specific goal (list building, launch support, or promoting a sale) and enough budget to test both simultaneously without spreading either too thin. For most ebook authors, Amazon Ads deliver more direct sales per dollar spent. For more on each channel, see Amazon Ads for Ebooks and Social Media Advertising for Ebooks.
Q: Can you run both Amazon Ads and Facebook Ads at the same time? A: Yes, and many successful authors do. The key is giving each platform enough budget to optimize ($5 to $10/day minimum per platform). Running both at $2/day each gives neither enough data to perform well.
Q: Which is cheaper, Facebook Ads or Amazon Ads? A: Amazon Ads typically have lower CPCs ($0.15 to $0.75) than Facebook ($0.30 to $1.50) for book-related audiences. Cost per acquisition is usually lower on Amazon because of higher conversion rates, but this varies by genre and targeting.
