Case Study: Grocery retailer achieves GDPR-compliant analytics and 35% shorter customer journeys with Piwik PRO

Online grocery prepared for the GDPR and optimized their website with Piwik PRO

Grocery Retailer, a leading online supermarket in Western Europe with over 7,000 locations, faced GDPR-driven requirements to secure customer data, collect compliant consents, host data in Europe with full ownership, and improve website usability across ~350 domains and subdomains. To meet these challenges they engaged Piwik PRO and its products (Piwik PRO Analytics Suite, Consent Manager, Tag Manager and Customer Data Platform) as a privacy-first analytics and consent partner.

Piwik PRO implemented a locally hosted Analytics Suite with Consent Manager and Tag Manager, managed the infrastructure, enabled data anonymization to fill analytics gaps, and used the Customer Data Platform to build audience clusters and link online behavior to local stores. As a result, Piwik PRO helped shorten paths to the branch finder and promotional booklet by 35%, increase newsletter signups by 17%, and raise consent opt-ins from 6% to 36%, while providing the retailer with GDPR-compliant, actionable omnichannel insights.
