Our cooperation company provides recruiting services to a broad range of other companies (“clients”). One of these services is active sourcing, i.e. they actively search for new employees by posting job ads on social media platforms. The social media platforms then display the ads to their user group. To use this service, clients provide a job description as well as additional information, e.g. the employee benefits offered, to our cooperation company.
During the experimental period, our cooperation company posts job ads in three different versions. Each user of the social media platforms can only see one version of the job ads. A user can either see a version highlighting that a job offers work-from-home, a version highlighting that a job offers flexible working hours or a version not highlighting any job characteristic. If a job only offers one of these employee benefits, e.g., it only offers work-from-home, the company does only post two versions, the version without any highlighted job characteristics and the one with the employee benefit offered, i.e. work-from-home. If a job does not offer any of the two employee benefits, it is not included in the experiment
The three versions are shown for up to two months. If the job ad is online for longer than two months, only the version that has generated the lowest costs per lead during the first two months will be displayed after that for budget reasons.
Update: Due to technical difficulties, who can see which version of the job ad is re-randomized after one month. This happens before I have had a chance to look at the data.
