— 01 · The challenge
Meta couldn’t see the sales.
After iOS privacy changes, Maison Mode’s Pixel was missing a large share of purchases. Campaigns optimised on incomplete data, ROAS sat at 2.4× and the team was close to cutting the channel.
Creative was refreshed rarely, and every audience saw the same ads whether they had never heard of the brand or had abandoned a basket yesterday.

— 02 · Our approach
Signal first, then scale the creative.
What we changed, in the order we changed it.
Step 01
Conversions API & deduplication
Implemented server-side Conversions API alongside the Pixel with proper event deduplication — capturing 97% of purchases.
Step 02
Simplified account structure
Consolidated fragmented ad sets into Advantage+ shopping and broad prospecting so the algorithm had enough data to learn.
Step 03
Weekly creative testing
Launched a steady cadence of UGC, try-on Reels and catalogue ads, keeping winners and retiring fatigued creative quickly.
Step 04
Full-funnel retargeting
Dynamic product ads for viewers and basket abandoners, with frequency caps and exclusions for recent purchasers.
— 03 · The results
From cost centre to growth channel.
ROAS more than doubled from 2.4× to 5.1× and cost per acquisition fell 38%. With reliable data, Maison Mode now scales Meta spend alongside Google Ads with confidence.
Measured over 4 months, in the client’s own ad accounts and CRM.

We were about to switch Instagram off. Once the tracking was fixed, it became our second most profitable channel.
