Challenge

A leading European luxury retailer was losing critical customer data, creating blind spots in their marketing attribution. With incomplete visibility into customer journeys and acquisition performance, they needed a solution to capture 100% of user interactions while maintaining compliance. Two key challenges were identified:

• Third-party tracking scripts severely degrading core web performance and user experience
• Data loss from ad blockers and Safari’s Intelligent Tracking Prevention, even with server-side tracking

Solution

The retailer deployed Edgee’s data collection solution, which operates as a first-party environment completely immune to ad blockers and browser restrictions. Enabling them to capture 100% of web interactions while maintaining full GDPR compliance and delivering real-time attribution across all marketing channels, from social media to paid search. This enabled the company to:

• Track user activity even in environments with ad blockers or Safari ITP
• Capture 100% of web interactions and behavioural data
• Monitor the entire acquisition funnel and attribute performance across all marketing channels (e.g. social media, paid ads, SEO)
