The three changes we would make first
01
Tracking counts sales twice
Meta reports 210 purchases a month. The shop shows 150. The pixel and the Conversions API send the same purchase without a shared event ID, so budget is being scaled on numbers that are 40% too high. Two ad sets that look profitable cost €190 per real customer.
- Fix
- Deduplicate events and reconcile against shop data every week. Move €4,000 a month from the two weak ad sets to the ones that win customers under €100.
- Worth
- About 20 more customers a month at the same spend.
02
Three ads carry the account, and they are wearing out
80% of spend runs through three ads. Each person sees them almost five times. Click-through has fallen 35% in six weeks, and cost per customer is rising with it.
- Fix
- Six new concepts across three angles, tested against each other, and fresh concepts every month after.
- Worth
- Bringing cost per customer from €120 back toward €100, about €3,000 a month at the current volume.
03
Paid traffic lands on the homepage
Ads send visitors to a homepage built for returning customers. Mobile conversion is 1.1%, and checkout requires creating an account first.
- Fix
- One landing page for the offer in the ad, with guest checkout.
- Worth
- Lifting mobile conversion to 1.5% means about a third more customers from the same clicks.
Estimated total
€4,000–6,000 a month
At current spend, before any increase in budget.
