Fixing a DTC account that was scaling itself broke
Revenue kept climbing while contribution margin fell for three quarters running, and the ad account looked fine throughout.
Where things stood
Two years of straightforward growth had stopped. Platform-reported return on ad spend still looked acceptable, but contribution margin had fallen for three quarters in a row. That is the usual signature of an account buying more of the same demand at rising prices while claiming credit for organic and returning-customer revenue.
Three things were true at the same time. Creative output had slowed to a handful of new concepts a quarter. The post-click experience had not been touched since launch. And email was running a welcome flow and not much else.
What we did
Changed the target. Reporting moved from platform ROAS to contribution margin after cost of goods, shipping, payment fees and media. Bidding and budget rules were rebuilt against a payback threshold the finance team agreed to.
Established what the spend was causing. Geo holdout tests on the two largest channels showed what was incremental, which moved a meaningful share of budget away from a channel that had been taking credit for demand it did not create.
Industrialised creative. Ad-hoc production was replaced with a concept, hook and variant framework on a fortnightly shipping cycle, so testing throughput stopped being the thing limiting growth.
Fixed what happens after the click. Product and landing page work, checkout friction removed, and structured testing on the pages carrying the most revenue.
Made retention a growth channel. A full lifecycle programme covering post-purchase, replenishment, winback and segmentation, because raising repeat rate raises what the business can afford to pay for a first order.
How it went
The account got smaller before it got better. Spend was cut in the channels that failed the incrementality test, and revenue dipped for a month while creative volume ramped up. That month was not comfortable for anyone.
