Case Study: Qube achieves sustainable lead growth with 303 London

Qube boosts monthly leads 16% with 303 London

The customer Qube partnered with 303 London to overcome a challenge with their paid media strategy. They were generating a high volume of low-quality leads and needed to shift their focus from cheap lead generation to a system optimized for sustainable, long-term growth and better lead quality.

303 London rebuilt Qube's paid media strategy around real business outcomes by implementing server-side tracking and a new campaign structure. This allowed optimization based on high-quality signals like MQLs and SQLs instead of just form fills. As a result, Qube saw a 16% increase in average monthly leads, a 56% increase in traffic volume, and a 20.8% improvement in click-through rate, creating a foundation for scalable growth.
