The A/B Test Vault: $3.28M a month in live wins

Every card on this page is a shipped A/B test on a real $10M-$300M DTC Shopify brand, with the actual before and after, the lift, and the move you can copy. Not a top-ten list. Not theory. Twenty-seven winners across apparel, supplements, candles, pet, beauty, cannabis, intimate wellness, and EDC, adding $3.28M a month in revenue. All of them are running in production right now.

The fastest way to read this: scan the brand and mechanism tags, find the card that looks like your store, and steal the move. Each one ships in a single design cycle and none of them need heavy dev.


The 27 wins, ranked by monthly lift

1. Goose Creek Candles: auto-expand the fragrance accordion

<aside> 🏷️

Brand: Goose Creek Candles · Vertical: Home / Candles · Page: PDP · Mechanism: UX (default state)

</aside>

On the candle PDP, the "This Fragrance" accordion was closed by default. People had to tap it to read the scent notes. You expanded it on load so the smell description is always visible.

Steal this: smell is the entire purchase decision for a candle, and burying it behind a tap cost six figures a month. Audit every collapsed section on your PDP. Anything that describes the actual product experience should be open by default.

2. Goose Creek Candles: move the shipping threshold into the cart

<aside> 🛍️

Brand: Goose Creek Candles · Vertical: Home / Candles · Page: Cart · Mechanism: Free-shipping mechanic

</aside>

They already ran a top-of-page "free shipping at $X" bar. You added the same progress bar inside the cart drawer, so the reminder lands at the decision moment instead of scrolling out of view.

Steal this: desktop did not need it because the top bar stays in view. Mobile responded hard because that bar scrolls away. Put the threshold progress bar in your cart drawer and segment the read by device.
