International customer survey at the POS with more than 9,000,000 participants

Since 2016 Lidl has been conducting customer surveys in more than 25 countries all around the world. After their purchase, customers are asked about their place of residence, receipt of the weekly advertising flyer and other topics.

Since the start of the project, over 9.2 million interviews have been conducted in Lidl stores. Provided address data is compared with stored street lists and automatically enriched by geocoordinates within the system. To secure the conformity with the data protection regulations in the respective survey countries, the data collection is anonymous.

Collected data is managed in a custom developed portal and displayed as charts. The obtained results provide valuable information for future expansion planning and the distribution of advertising material.
