Case Study: École Polytechnique achieves 1060% ROI with LinkedIn Marketing Solutions

Investing in LinkedIn targeting transforms ROI for École polytechnique

École Polytechnique, France’s top engineering school, needed to launch an Executive Master in just four months and reach a new audience of senior professionals (7+ years’ experience) interested in technology and innovation. The team had to raise awareness, drive traffic and registrations, and convert inquiries into applications using channels they hadn’t used before.

By combining LinkedIn Sponsored Content for broad awareness with highly targeted Sponsored InMail for personalised calls-to-action—segmented by country, sector, company size and job function—the campaign drove roughly half of all inquiries and applications, 53% of brochure downloads and 40% of information-session registrations. Sponsored Content achieved a 1.8% CTR while InMails in France saw >50% open and >30% click-through rates, delivering a 1060% ROI.
