CRO Without Big Numbers: Personalization in The VodafoneZiggo Way - Daniël Granja Baltazar

Not Enough Traffic for A/B Testing?

Here’s How VodafoneZiggo Scales Personalization Anyway

📉 In B2B marketing, low traffic volume is often a CRO killer. But that hasn’t stopped VodafoneZiggo from building a smart, insight-driven personalization engine anyway.

In the latest episode of the Hello $Firstname podcast, I had the pleasure of speaking with Daniel Granja Baltazar, CRO Specialist at VodafoneZiggo, about how his team is rethinking Conversion Rate Optimization and Personalization in a B2B context—where statistical significance isn’t always an option, and complexity is the norm.

Daniel shared how qualitative research, from customer interviews to service center conversations, plays a central role in shaping the personalized customer experience. The transcripts and insights collected feed directly into the Personalization Layer—alongside behavioral data—and are then activated across web and email touchpoints.

🔍 Key Insights from the Episode

🎯 Why qualitative research is the backbone of B2B CRO With limited traffic and massive variation in the SME segment, Daniel's team relies heavily on qualitative methods—interviews, feedback loops, and even in-person time at customer service—to shape hypotheses and content strategies.

🧠 From assumptions to insights: how interviews feed content strategy By analyzing common misunderstandings and recurring questions, the team uncovers "invisible friction" in the journey—then translates that into smarter, simpler content that helps guide customers toward the right solution.

📬 Lifecycle content that prevents service calls Many of the best content ideas come directly from the call center. Proactive outbound emails that answer questions before they’re asked can save thousands of service hours—and create a better experience in the process.

🌐 Personalization in B2B is about people, not just companies At VodafoneZiggo, they’re working toward tailoring content not just by segment or industry, but by the individual’s role, preferences, and behavior—whether that’s a founder, an IT manager, or someone else entirely.

🤖 Generative AI as a CRO co-pilot Daniel also shares how their internal GPT instance helps summarize interviews, categorize feedback, and analyze large sets of qualitative data—saving time and enabling faster learning.

🔗 How It All Connects to the CX Layers

Daniel’s approach aligns beautifully with the CX Layers framework—with qualitative insights feeding the Content Layer, behavioral signals informing the Data Layer, and personalization being orchestrated across inbound and outbound channels.

It’s a great example of how Experience Optimization in B2B isn’t about volume—it’s about relevance. And sometimes, it starts by just sitting down and listening to your customers.
