Case Study: KNB Online Inc. achieves up to 12,280% client ROI with AdRoll

How Kevin Brkal Drives Incredible ROI for KNB Online Clients with AdRoll

KNB Online, led by Kevin Brkal, is a boutique digital agency that helps ecommerce businesses overcome wasted ad spend and poor campaign execution common at larger firms. Facing platform changes, privacy-driven data limits, and agencies that miss basic retargeting and targeting opportunities, KNB needed a reliable, data-driven way to reach high-value customers and improve return on ad spend.

The team rebuilt strategies around AdRoll’s retargeting, brand awareness, and managed services—using HTML5 creatives, lookalike and contextual targeting, and a deliberate split between cold and retargeting budgets—while giving clients full account transparency. The approach delivered dramatic results: clients saw ROIs like 12,280% ($5,654 → $700,000), 3,463% ($14,528 → $517,777), and 781% ($12,755 → $112,447), routinely achieving 9x+ ROAS and strong attributed revenue gains.
