We introduced Performance Max (pMax) campaigns and restructured Shopping activities to focus on high-converting SKUs. This strategic shift led to a 152% increase in ROAS, achieving an impressive 10.82x return. Revenue soared, with Shopping campaigns alone generating £374k at a 5.58x ROAS.
On TikTok, we developed a full-funnel approach using trend-driven content that resonated with Belier’s audience. Over 12 months, our campaigns generated £140k in revenue from a £33k spend, delivering a strong 4.23x ROAS. Our strategy focused on creating ads that felt organic, driving engagement and conversion throughout the customer journey.
By activating programmatic display campaigns across all funnel stages, we broadened Belier’s brand presence beyond traditional platforms. This approach supported retargeting efforts and introduced new sources of traffic, ensuring continuous growth and engagement.

We restructured ASSOS’s Paid Search and Shopping campaigns, optimising ad spend and prioritising high-converting products. The result? A dramatic increase in CTR from 10% to 32% and an additional 225% in revenue, almost doubling their previous performance.
By activating campaigns across all funnel stages and introducing new creative formats, we broadened ASSOS’s reach beyond Google and Facebook. This strategy drove significant traffic, supported global retargeting, and ensured that ASSOS’s brand remained top of mind across multiple platforms.
We refined audience targeting, stacked interests and lookalikes, and utilised Ad Set Budget Optimisation (ABO) to give Facebook’s algorithm more flexibility. This led to improved ROAS, reduced CPMs, and allowed ASSOS to reach broader, more engaged audiences.
To reduce reliance on traditional digital platforms, we launched ASSOS on two new display channels and expanded into Canada, Australia, and Benelux. These efforts not only increased YouTube views and programmatic channel activity but also opened up significant new revenue streams.
Our expertly timed campaign for the Archive Sale—ASSOS’s biggest sales event—generated over 400% in revenue with a ROAS of 4.8.
Over 80% of this came directly from our campaign, solidifying its success.
