The task

The account was spread across 17 campaigns. As a result, budget and data were distributed across too many small units.

What we did

In March 2026, we consolidated the 17 campaigns into 8 and reviewed the conversion tracking. Since then, we have managed budget and bids by inquiries.

The result

54% lower cost per inquiry in March 2026, with 60 inquiries and a 47% higher click-through rate. By July 2026, the cost per inquiry fell further to €141.39, 44% less than in March, with 62 inquiries.
