How Diffusion reversed a 30% revenue decline and scaled profitably with Meta Ads.
The Brand
Diffusion is an established Irish boutique founded in 1991, originally operating from Clontarf, Dublin before transitioning fully online in 2015. Curated by founder Kate, the brand focuses on timeless, handpicked fashion pieces designed to mix, match and be worn season after season.
Operating as a multi-brand boutique model, Diffusion works with limited stock depth across a rotating mix of brands, making inventory management and product selection critical to performance.
The Problem
Diffusion had built its reputation through strong organic demand and loyal returning customers. However, by early 2025, revenue had begun to decline, with sales down close to 30% year-on-year in the first quarter.
The business had no structured paid acquisition system in place and was heavily reliant on organic performance. There was no scalable engine to consistently attract new customers, and growth had plateaued.
To move forward, Diffusion needed Meta to become a reliable source of profitable new-customer growth, reducing their dependence on organic alone.
“Heavy Head Social didn’t just run ads, they brought clarity, structure and a real growth strategy to our business at a critical time.”
Their Goal
Diffusion’s goal was clear: grow revenue, increase new customer acquisition, and reduce reliance on organic channels, all while maintaining profitability.
Because of the boutique retail model and limited stock units per SKU, scaling had to be disciplined. The objective wasn’t aggressive spend; it was controlled, profitable growth that took stock depth and product mix into account.
The Strategy
Because Diffusion had never run Meta Ads before, we built the account from scratch with new-customer acquisition at the centre.
Their boutique model meant we couldn’t manage Meta in isolation. Stock moved quickly, key sizes sold out and new products arrived constantly, so what we advertised had to move with the business.
Product mix became central to performance. We avoided relying too heavily on one section or bestseller, continuously introduced newness, and monitored stock closely so products could be removed as key sizes sold through.
Creative diversity was equally important. Rather than relying solely on try-on videos, we used a balanced mix of formats to reach different customers and continually give Meta new opportunities to find buyers.
The result was Meta working around the realities of the business, rather than blindly scaling whatever happened to be performing inside the ad account.
The Result
Our efforts delivered a clear performance turnaround for Diffusion:
Revenue Reversal: Shifted from a near 30% year-on-year decline to consistent double- and triple-digit monthly growth.
+264% Revenue Growth: Achieved in June compared to the previous year.
+140% Revenue Growth: Delivered in October during the scaling period.
+276% Increase in Orders: Significantly increased order volume during peak growth months.
+163% Increase in New Customer Rate: Built a sustainable acquisition engine rather than relying on repeat buyers.
8x Average MER: Maintained strong profitability while scaling.
4x Average aMER: Ensured acquisition-driven growth remained sustainable.
These results reflect more than revenue growth. Diffusion went from relying heavily on organic demand to having Meta consistently bring new customers into the business while maintaining strong profitability.
After several months of profitable growth, Diffusion chose to bring Meta execution in-house, with a clear structure and proven approach already established.
