The scaling problem

Scaling paid media for a fashion brand is harder than it looks from the outside. You can increase budget. What's less clear is whether performance holds as you do. The brands that scale paid well aren't just spending more. They're managing the tension between reach and relevance, between volume and efficiency, and between short-term ROAS and long-term customer economics.

Boy London came to us with a paid programme that worked at a certain level. The challenge was that every attempt to push budget meaningfully higher had resulted in ROAS deterioration. The team knew the creative was strong. They knew the product had an audience. But the ceiling on performance kept appearing at roughly the same spend level.

What we found

The account had too few creative assets running for the budget level. Three to five ads were carrying the majority of spend. Creative fatigue was setting in within three to four weeks of launch. By the time new creative was briefed, produced, and live, the existing ads had already degraded significantly.

Audience structure was contributing to the problem. Multiple ad sets with overlapping targeting were competing against each other in the auction, driving up CPMs across the account. Warm audiences and cold prospecting were running concurrently without clear separation or budget logic.

Attribution was being read optimistically. Meta's reported ROAS looked reasonable. Shopify revenue told a different story. The gap was significant enough that the account appeared to be performing better than it was, which delayed the diagnosis.

What we changed

Creative was the first fix. We moved to a minimum of 15 to 20 new assets per month, weighted toward UGC-style formats and creator content. Boy London's brand aesthetic is strong and distinctive, but the feed rewards native-feeling content alongside editorial. The testing cadence changed: concept and angle first, then hook, then format.

The audience structure was rebuilt. We consolidated from multiple overlapping ad sets to three clear objectives: broad cold prospecting through Advantage+, a retargeting set for engaged non-purchasers, and a separate campaign for existing customers with different creative and messaging. Exclusions were added throughout.

Reporting was aligned to blended CAC rather than Meta-reported ROAS. This gave a more accurate view of actual performance and removed the optimistic attribution bias that had been masking the real efficiency picture.

What happened

Within 60 days of the account rebuild, we were able to increase daily spend by 40% without the ROAS deterioration that had characterised previous attempts to scale. The creative refresh cycle was the primary driver. The algorithm had more to work with, which meant it could find new audiences and new angles rather than exhausting the same assets.

By month four, spend had doubled from the starting point. Blended CAC was lower than it had been at the previous spend level. The brands that can't scale paid are almost always either running too few creative assets or too concentrated in warm audiences. Usually both.
