The problem

The campaign generated conversions, but 221.05% ROAS and $37.68 cost per conversion limited profitable scale. Search relevance, signals, assets and location efficiency needed closer control.

What we did

We reviewed campaign structure, search-term insights, high-intent search themes, audience signals, ad copy, assets, locations, negative keywords and creative quality. Daily monitoring connected each change to ROAS, conversion value, CPA and conversion-rate trends.

The outcome

ROAS increased from 221.05% to 341.37%, CPA fell from $37.68 to $20.71 and conversion rate increased from 6.56% to 9.86%. The 49-day post-optimisation period recorded 1.63K conversions and $115K in tracked conversion value.

Why this matters

The campaign created more room to scale because acquisition efficiency improved alongside conversion value.
