System 03 — systems
Conversion is a queue,not a redesign.
The Listing & Conversion System mines search terms, reviews, and CVR by placement into ranked hypotheses — then tests them in order. Median winning test in 2025: +18% CVR. 3 of every 7 tests lose, and the losers ship learnings.

What it replaces
The redesign that changed nothing. Measurably.
Twice a year, someone rewrites the listing. The founder likes it. The agency invoices it. CVR does what it was always going to do — because nobody tested anything.
Opinion in, invoice out. No control group, no significance, no memory — the same debate repeats next cycle with the same evidence: none.
Hypotheses ranked by expected impact × confidence. Tests stop at significance, winners ship into SOPs, losers are logged. The debate ends because the queue answers it.
The mechanism
Every listing decision has a test ID.
Hypotheses come from data the account already generates — what buyers search, what reviews complain about, where sessions die.
One variable per test, stopped at 95% significance. No peeking, no calling it early because it "looks done."
Losers are assets. A failed test closes a debate permanently — the 43% that lose are why the 57% that win are trusted.

63% — the lowest of the 4 systems, on purpose. Creative is judgment. We automate the measurement around it, not the taste inside it.

Which hero image converts?
Variant B shipped: +18% CVR. The SOP now requires in-context hero imagery for this category.
Client scorecard · US marketplace · Q1 2026A B test result: variant A, on-white control, converted 11.2 percent. Variant B, in-context, converted 13.2 percent with 4,180 sessions per arm at 95 percent significance over 11 days.
SKUs under ~800 sessions/month can't reach significance. We don't test them — we apply category SOPs and say so, instead of shipping noise dressed as science.
