Case Study: Vodafone achieves 40% incremental sales and higher-quality leads with Quantcast's cookieless solution

Vodafone dials up higher quality leads and more sales with Quantcast’s cookieless solution

Vodafone, a leading global telecommunications company, faced the industrywide shift away from third‑party cookies and needed a cost‑effective way to reach audiences and measure conversions in cookieless browsers like Safari and Firefox. The company wanted to assess how prospecting in cookieless environments compared to traditional cookie-based advertising while driving incremental customer sales.

Partnering with Quantcast, Vodafone ran identical customer‑acquisition campaigns—one cookie-based and one fully cookieless—using Quantcast’s autonomous audience selection and cookieless conversion reporting. The cookieless campaign delivered strong results: 40% of total sales came from cookieless advertising, leads converted 25% better, and cost per sale was roughly 20% lower.
