“The founders thought their Meta ads were broken. They weren't. The leak was between the click and the checkout.”
CAC down 38% in 90 days — same ad spend, sharper system.
A bootstrapped D2C skincare brand was spending roughly ₹4.8L a month on Meta for a 1.6% sitewide conversion rate. The team had already "optimised" the ads three times. Every optimisation moved CTR by 10% and CAC by zero — because CAC isn't an ads problem if the leak is downstream.
- Audited all 184 live creatives against their 90-day performance window. 72% had never recouped their CPM — we paused them and doubled down on three ugly-duckling winners the brand had almost killed.
- Rewrote the product detail page so the messaging matched the ad. The mismatch between "gentle for acne-prone skin" in the ad and a dense ingredient wall on the PDP was the single biggest bounce driver.
- Launched a 9-touch email + WhatsApp sequence for abandoned carts and first-time buyers. Separate tracks for each: abandoners got a use-case education arc, first-time buyers got an onboarding arc.
- Kept monthly ad spend flat through the entire 90 days — this was deliberate. We wanted the CAC drop to come from the system, not more money.
