Bringing the Best Practices to the Team

Market challenges

  • Scaling SEA across four distinct European markets simultaneously, each with different competitive dynamics, search behaviours, and conversion patterns.
  • Maintaining acquisition cost efficiency while pushing for volume growth across multiple languages and geographies.

Paid challenges

  • Google and Bing accounts lacked the structure needed to maximise performance across four markets.
  • Best practices weren't consistently applied, creating inefficiencies that capped growth potential.
  • Limited visibility into what was actually driving conversions made confident scaling difficult.

What we did

Rebuilt the SEA engine across four European markets โ€” bringing structure, best practices, and a clear performance framework that unlocked confident scaling.

1. Account Restructure & Organisation: Audited and reorganised Google and Bing accounts across all four markets โ€” creating a clean, scalable structure that made performance drivers immediately visible.

2. Best Practice Implementation: Embedded SEA best practices across bidding, campaign architecture, and keyword strategy โ€” eliminating inefficiencies and raising the performance baseline across every market.

3. Multi-Market Scaling: Pushed conversion volumes systematically across France, Italy, Spain, and Germany โ€” balancing growth with acquisition cost control to ensure efficiency at scale.
