Stellantis partnered with Integral Ad Science and Publicis Media to implement attention measurement across its global media strategy, deploying Quality Attention across 19 countries and 20+ brands with over 13 billion measured impressions. The initiative revealed that attention drivers varied by market – visibility in the US versus lower clutter in Europe – enabling refined media allocation strategies. Results demonstrated significant business impact, including a 165% increase in engagement on high-attention inventory and a 33% increase in ad recall among key audiences.
