Black Box

The ad platforms stopped telling you what they do with your money.

Here's how to run them anyway.

Black Box: Running Ads on Platforms That Stopped Explaining Themselves is a book in the Indie Author Guide Line: short, source-checked guides for independent authors who have finished writing and now have to be found. This one is about a specific, uncomfortable fact. The major advertising systems have grown steadily more opaque, reporting less and explaining less while still taking the spend. Amazon and Facebook will happily run your ads. They will not tell you, in any detail you can trust, what your money actually did.

Every platform behavior described in this book carries a date, and points you at the live dashboard rather than a frozen screenshot, because ad systems change under you between editions. There are no "winning campaign" formulas and no promise that a tactic here will still work by the time you read it. What you get instead is a testing discipline: what you can still measure, what a click and a read-through are actually worth to you, what the auction is doing behind the number it shows you, and how to test spend without lighting money on fire chasing figures the platform will not show you.

What's inside:

• What the platforms used to report, what they report now, and exactly where the gap opened up
• How to figure out what a click, an impression, or a read-through is worth to you, independent of what the platform claims it's worth
• What the auction is actually doing with your bid, to the extent that's knowable, and what to stop assuming about it
• A testing discipline for spending small and checking your own numbers, instead of chasing a platform's dashboard toward a "win" that resets the moment its algorithm shifts
• How to tell the difference between a real signal and noise when your sample size is an indie author's budget, not a corporation's
• What to do with the anxiety of spending money into a system that won't explain itself back to you

This is not a course promising you a winning campaign, and it will not tell you an amount to spend. Nobody honest can. What it will do is tell you what these platforms will and won't show you in July 2026, and give you a way to test your own spend that doesn't depend on the platform ever becoming honest.
