A Facebook Case Study
Welks (保育のお仕事) is an online recruitment service specializing in childcare, nursing, rehabilitation and welfare services. After running Facebook ads to build its “Childcare Jobs” membership, the company sought to improve ad placement and efficiency to acquire more customers while reducing management time.
Welks added the Facebook pixel, used Custom and Lookalike Audiences, and ran photo and carousel ads across Facebook, Instagram and the Audience Network, testing and adjusting creatives daily. The streamlined, cross‑placement campaign cut lead cost by 50%, increased daily leads 4×, and simplified campaign management.
