Case Study: Leading Public Relations Firm achieves $10.41 eCPA and 2,000+ conversions with Centro

Leading Public Relations Firm - Customer Case Study

Leading Public Relations Firm engaged Centro to help promote an energy initiative and drive positive perception by signing the target audience up for an email list with a CPA goal under $15. The PR firm struggled to reach users across multiple site types with relevant content (national security, conservative political, jobs, and labor), so Centro was brought in to provide targeted digital buying support using Centro DSP.

Centro implemented contextual targeting across the identified site types, used Centro DSP to identify correlations between national security and political content viewers, isolated high-value domains for retargeting, and expanded reach by uncovering additional content verticals. The campaign generated over 19 million impressions, more than 2,000 conversions, and achieved an eCPA of $10.41—well below the $15 goal—prompting the Leading Public Relations Firm to pursue further campaigns with Centro.
