The challenge
Lumio's GA4 showed 'direct' traffic as the second-largest source. The growth team assumed it was brand loyalty and couldn't explain why it doubled during influencer campaigns. Without visibility, budget was being wasted on channels that looked scalable but weren't.
How Zobrx helped

Let the AI Advisor narrate the weekly GA4 story to the CEO and Head of CX.
The results
The team discovered 70% of 'direct' traffic was coming from WhatsApp group shares of Instagram Stories. They launched a formal WhatsApp channel, broadcast program, and click-to-chat ad strategy. In 6 months, they recovered $4.1M in attributable revenue, cut blended CAC by 26%, and doubled repeat purchase rate.
"Zobrx caught that 70% of our GA4 'direct' traffic was actually dark social from WhatsApp groups. Re-attributing that unlocked a whole new channel strategy."
