Scale revenue while protecting contribution margin.
Overview
The situation.
This store had proven it could sell—the question was whether it could grow without giving the margin back. Every time spend increased, returns on ad spend fell, and one-time buyers rarely came back for a second order.
The account relied on a handful of winning ads that had been running for months. Audiences were saturated, creative fatigue was setting in, and the product feed hadn't been touched since launch. Email existed only as a monthly newsletter, so nearly all revenue depended on paid traffic finding new customers.

Approach
How we tackled it.
The first month stabilised measurement and rebuilt the feed. Creative testing ran in weekly rounds from month two, with winners graduating into the scaling campaigns. Email flows launched in parallel, and by month three repeat revenue was meaningfully contributing to blended returns—giving the paid campaigns room to scale into.
Structured creative testing
A weekly testing rhythm separated hooks, formats and offers, so every round produced a clear learning instead of a guess.
Feed and Shopping hygiene
Titles, images and attributes were rebuilt around how people actually search, improving both Shopping and Performance Max efficiency.
Post-purchase flows
Welcome, post-purchase and win-back email sequences turned one-time buyers into repeat customers, raising the value of every order the ads produced.

Questions
Questions about this kind of engagement.
How much creative volume does this need?+
Enough to test weekly—typically four to eight new concepts a month, mixing video and statics. The discipline of the testing rhythm matters more than any single ad.
Why did email matter to ad performance?+
Repeat purchases raised customer lifetime value, which raised the return target the ad account could profitably chase. Retention and acquisition reinforce each other.
What was the first thing fixed?+
Measurement. Until revenue and margin signals were trustworthy, every other decision was guesswork.
