Title/cover and bundle A/B on one book: zero sales on A$85

By Ryan Richardson · Published 8 October 2026

Two small tests ran on The Accidental CTO field guide: a title-plus-cover-design CTR screen, and a single-book-offer versus two-book-bundle A/B test. Combined spend was A$85.27 across 76 ads, with zero recorded purchases.

The question

Before committing further budget, which title+cover combination screens best on CTR, and separately, does bundling the field guide with a second book outsell the single-book offer?

What won, and how sure to be about it

Both sub-tests ran on small spend (under A$50 each) and produced zero purchases, so neither can declare a winning title/cover combination or a winning offer structure. The bundle test in particular ran 56 ads against only 1,153 impressions and A$40.32, under a dollar of spend per ad, which is too little exposure per variant to read even the CTR comparison with confidence.

What we changed next

No documented follow-on decision from either sub-test was found in the pulled sources.

How to run this test yourself

Running 56 ad variants on a combined A$40 budget spreads spend too thin to read per-variant; a bundle-vs-single-offer test needs a small number of variants (2-3) each given enough budget to clear a few hundred impressions before the comparison means anything.
