Reach

For three vacancies across three cities we ran six Meta campaigns side by side, each with its own creative and a short application funnel. Together they produced 93 application leads in just over five weeks, across a reach of 19,321 people and 65,293 impressions. The Amsterdam customer service campaign performed strongest with 51 leads; the Den Bosch and Sittard campaigns added the rest. Weaker variants were switched off along the way so budget flowed to the winners.

Assumptions
- Applications in this case: 93
- Your placement rate: 10%
- Staffing - gross margin per temp worker per year: € 10,000
- This case ran without ad spend, so we only show the estimated pipeline value.
Source: Staffing rates work with a conversion factor of 1.9 to 2.6 on gross hourly wage (2026). The agency's margin sits around 20-25% in technical work and 35-40% for general production work. At a gross hourly wage of EUR 16 and factor 2.1, the client pays EUR 33.60 per hour; the agency's gross margin typically comes to EUR 4 to EUR 7 per hour worked, or EUR 7,000 to EUR 12,000 per year per temp worker.
This is a model, not a realised result. Adjust the assumptions to your own margins and placement rate.
