THE SITUATION

The dual win: growth and efficiency together

Discover how precise spend direction grew UK sales 177% year-over-year while cutting TACOS in half.

THE STARTING POSITION:

✕

UK marketplace performing well below its potential relative to the brand’s strength

✕

Efficiency already reasonable — making further gains harder, not easier

✕

Growth that needed to come from precision, not just bigger budgets

When ads stop subsidising the wrong traffic, two things happen at once: the same spend buys more sales, and organic momentum compounds on top. That’s how TACOS halves while sales nearly triple.

THE STRATEGY

The objective: Unlock the UK marketplace’s growth potential while improving an already-decent efficiency baseline.

1

Initial Optimisation

  • Eliminated residual waste and corrected misdirected bids
  • Quick wins banked while the restructure was built
2

Restructure For Control

  • Refined keyword groups and buckets on exact match targets
  • Every pound of spend pointed at terms with proven conversion
3

Compound The Momentum

  • Scaled into winners as organic rank strengthened
  • Momentum accelerating: May 2026 finished +226% vs May 2025
THE RESULTS

What changed
