Slurm.io Grows Kubernetes Course Registrations 150% with 300% ROI
EZCA ran a targeted multi-platform paid campaign for Slurm.io's Kubernetes course — tripling registration volume and delivering 300% ROI on ad spend through precise DevOps audience segmentation.
Slurm.io is a technical education platform for developers and DevOps engineers. EZCA built and ran paid campaigns across Google Ads, Yandex.Direct, and social media to promote their Kubernetes course, achieving 150% growth in registrations versus the prior period and 300% ROI on the advertising investment.
Slurm.io had a strong Kubernetes course but limited reach into the DevOps and systems administration audience that needed it.
Slurm.io had built a credible library of technical courses for IT professionals and developers. The Kubernetes course was high-quality, but awareness among the target audience — engineers evaluating container orchestration training — was low. The challenge: DevOps professionals are a specialized audience that requires precise segmentation by technical interest, skill level, and geography. Generic ad targeting wastes budget on irrelevant users; the course needed to reach exactly the practitioners searching for container management training. Without a structured paid acquisition program, enrollment growth was organic and slow.
EZCA ran a precision multi-platform campaign — segmented by technical interest and skill level, with daily optimization and systematic creative A/B testing.
EZCA started with detailed audience research to map the interests, learning needs, and online behavior of Kubernetes course candidates: developers, DevOps engineers, system administrators, and IT operations staff. Platforms were selected based on where this audience was reachable — Google Ads, Yandex.Direct, and social networks. Campaigns were built with tight targeting: technical interest segments, skill-level filters, and geographic targeting. Ad creatives and copy were developed to emphasize the unique depth of the Kubernetes curriculum. A/B testing was run continuously across formats, audiences, and messages. Daily monitoring allowed fast iteration — underperforming placements and audience segments were cut quickly, budget shifted to what converted. Audience feedback was incorporated in real time to sharpen the creative and targeting approach.
Slurm.io's Kubernetes course registrations grew 150% and ad spend delivered 300% ROI — proving that DevOps audiences convert when reached with the right message on the right platform.
Registrations for the Kubernetes course grew 150% compared to the period before EZCA's campaign — a direct result of precise audience targeting and continuous optimization. ROI on advertising reached 300%, making the paid acquisition program self-evidently viable to scale. Page traffic to the course on Slurm.io increased significantly, building awareness among the broader DevOps community beyond direct converters. The campaign framework — audience segmentation by technical specialty, daily iteration, and systematic creative testing — is directly transferable to other technical courses on the platform.
