McArthurGlen, a leading developer of designer outlet villages in Europe, faced a dilemma about whether to standardize their brand communication strategy across multiple countries. Lucidity London was commissioned to evaluate the effectiveness of McArthurGlen's pan-European "Guilt-Free Shopping" advertising campaign by analyzing footfall data from three villages over three years. While the campaign coincided with growing footfall and sales, the analysis found the campaign was only partially implemented in some markets due to cultural differences. It also highlighted the need for McArthurGlen to better measure advertising performance in individual countries. In the end, Lucidity London recommended retaining the standardized strategy but emphasizing local adaptations and best practices.
