A $14 part that stands between a house and a flooded floor
Conversion 6.4% → 10.5%
The brand sold supply lines and shutoff valves on price, against competitors four dollars cheaper. The relevant number was never the price of the part — it was the cost of the part failing.

The challenge
Everything the brand sold was a small part that spends its life out of sight — behind a cabinet, under a floor, inside a wall. On a search page those parts are indistinguishable from the ones costing four dollars less, and the brand had been fighting that gap the only way it knew: with specification bullets about burst pressure and braid count, which mean nothing to the person buying.
What the copy never mentioned was the only thing that makes the four dollars rational. When one of these parts lets go, the damage is not the part — it is a kitchen floor, a ceiling below, weeks of drying equipment and an insurance claim. That asymmetry is the brand's entire argument, it is what every positive review is really describing, and it appeared nowhere on any listing in the category.
Our approach
We stopped selling a component and started selling the consequence it prevents.
- The stake stated in the image stack — what fails, where the water goes and what it costs, placed before any specification.
- A replacement-interval argument, since these parts are usually left in place until they fail and almost nobody knows they have a service life.
- Whole-house framing — every fixture that carries one of these parts named, which turns a one-item purchase into a walk-around.
- Campaigns following the consequence — searches about leaks, damage and prevention, which the specification-led competitors were not bidding on at all.
Inside the ad account

Anonymized account view, rebuilt from the figures reported above: ad sales growing from $43k to $104k a month while ACoS falls from 36% to 22% across the 8-month engagement.
The results
Conversion went from 6.4% to 10.5% and revenue grew 142%, with the price gap against the cheap competitors left exactly where it was.
Units per order rose 48% — the whole-house framing working: a shopper who understands what a failed connector costs does not replace one and leave the other five. ACoS fell fourteen points because the prevention-shaped searches are cheap, uncontested and full of people who have already decided the four dollars is worth it.
“We were arguing about four dollars with a customer whose real exposure was a forty-thousand-dollar floor. Nobody had ever said that out loud on the page.”
