The challenge

The company sells online and through more than 300 specialist stores. Its existing data captured only part of the journey from first ad contact to purchase.

What we did

We revised how purchases are attributed to ad interactions and introduced automated bidding with a target ROAS. Ad variants were created with AI assistance, and cross-device signals were factored in. The analysis was used to allocate budgets based on each campaign's contribution to revenue.

The result

41% higher return on ad spend (ROAS) for local inventory ads: 1,282% in 2025, up from 907% in 2024. Across all campaigns with an internal budget, ROAS reached 2,853% in 2025. Store visits are included in these figures at a flat €23 per visit.
