The Most Expensive Way to Spend $500
October 31st, 2026 • 4 minute read • Issue #178
Your first $500 on Facebook Ads isn’t buying sales.
It’s buying answers.
I know that’s not what most of us hope for when we set aside an ad budget. We picture the $500 going out and roughly $500 coming back, maybe a little more. Break-even by the end of the month, then we turn the dial up.
It almost never goes that way. And I think that’s where a lot of good books get left behind.
What $500 Actually Buys You
When I started running Facebook Ads for my wife’s books back in 2020, I was spending about £10 a day. Do that for six weeks or so and you’ve spent about $500.
Our first month of royalties was $133.
If I’d judged those first few weeks on profit, I’d have stopped. Plenty of authors do, usually around week two or three, when the royalties aren't living upto their hopes, dreams and expectations.
But that £10/day I spent back in 2020 wasn’t wasted. It was tuition. It told me things about the book that no amount of guessing could have.
Here’s what your first $500 on Facebook is really telling you:
→ Does your ad stop the scroll? Look at your CTR (Click-Through Rate) in your Facebook Ads dashboard. If plenty of people see your ads and very few click, the way you've positioned the book isn’t landing with the readers Facebook is showing it to.
→ Does your book product page close the deal? Facebook can’t see your Amazon sales, so put your link clicks next to your sales and Kindle+ page reads in Amazon Attribution. Traffic from Facebook Ads to Amazon usually converts somewhere around 1% to 5%. If you’re well below that, the leak is usually the blurb, the reviews or the Look Inside, not the ad.
→ Does your price fit the market? If people are clicking but not buying, compare your price with the books sitting beside yours in your genre. And if you earn most of your royalties from Kindle+, the issue isn't price, it's something else on the page.
→ Which readers actually want this book? Run a small group of ads, each with a different angle, such as: one leading with a trope, one with an excerpt from the book, one with a reader review. Facebook will lean towards the ones that work and show each to slightly different pockets of readers. Analyze which angle is receiving the most budget; that's the one to dial in further.
Four questions. Every one of them is worth answering before you spend $5,000.
Why Break-Even Is The Wrong Goal
Judging your first $500 on break-even is a bit like judging the first batch of a new recipe on whether it’s good enough to serve at a dinner party.
It isn’t meant to be. It’s the batch you taste, so you know whether it needs more seasoning.
Facebook is learning too.
In the early days, it’s working out who responds to your ads, and it needs spend to do that. Every time you switch an ad off in a panic or rewrite it on day four, you send it back to the start.
The authors I’ve seen go on to do well from Facebook Ads treated their early spend as tuition. They didn’t ask, “Did I make my money back?” They asked, “What did this tell me, and what do I fix?”
Then they fixed it. A new cover. A rewritten blurb. A price test. And they ran the next $500 against a better version of the same book.
The ones who stall tend to do the opposite. They spend, see red in week two, decide “Facebook Ads don’t work for my genre,” and stop. The money’s gone, and they've learned very little from it, because they left before the answers came in.
That’s the expensive version. Not the spending, but walking out halfway through the lesson.
The Honest Numbers
Here’s how I’d frame the first $500 of ad spend:
Count it as research, not revenue. If some royalties come back, that’s a bonus. If you break even, you’re ahead of most.
Give it enough to say something. Five dollars a day for a week won’t tell you much. Around $15 a day for a month, across a small group of ads, will.
Let it breathe. Check in every few days, not every few hours. Resist the urge to tinker while Facebook is still learning.
Read your numbers in the right places. Your Facebook Ads dashboard tells you about the ad. Your KDP dashboard tells you about the book. Amazon Attribution tells you which ads are pulling their weight and which aren't.
Decide before you start what you’ll do with each answer. Low CTR, look at the image and the hook. Healthy clicks but few sales, look at the book product page and the price. One angle pulling ahead, write more ads like it.
If you have a series, or a catalog of standalones that lead into each other, there’s one more piece.
A reader you win with one book may go on to buy three, four or five more.
A $500 test that looks flat on that first book can look very different once read-through arrives a few weeks later. Give it time to land before you call it.
When It Starts To Pay
None of this means Facebook Ads should lose money forever. The whole point of the tuition is to get to the part where they don’t.
Once the foundations hold (the cover, the blurb, the price), the next $500 has a very different job. It stops asking questions and starts buying readers.
That’s the order that works: foundations first, then one platform mastered, then scale. For most fiction authors, that one platform is Facebook Ads.
Your first $500 is simply how you find out which foundations need the work.
That’s it for this week.
Thanks for reading. See you next Saturday.
