About Author Ads Pro

Author Ads Pro makes Amazon Ads tools for authors who write series and publish in Kindle Unlimited. Every tool judges ads the way a series actually earns: sale royalties, page reads, and the books readers go on to read.

Who builds it

I'm Michael Cortez. I run paid search and SEO for small businesses for a living: keyword research, search term reports, bids, negatives, and the weekly grind of deciding what to change. When I looked at how authors are told to judge Amazon Ads, the standard advice (break even at your royalty rate, cut anything over it) ignored the two things that make a KU series work: page reads and read-through.

So I built the tool I'd want if I were running ads on my own series: bring the search term report, enter your series numbers, and get the exact changes to make, with the reasoning shown.
