The objective<\/strong><\/h3>\n\n\n\n

UEFA\u2019s <\/strong>Men\u2019s Club Competitions Online Store (operated by Event Merchandising Ltd), supporting fans of the massively popular UEFA Champions League and UEFA Europa League, chose TikTok<\/strong> to promote its clothing and accessories website during the 2024 finals. UEFA cares deeply about privacy and needed a solution that allowed it to measure the impact of its advertising on TikTok without sending any user personal information to the entertainment platform directly.<\/p>\n\n\n\n

The solution<\/strong><\/h3>\n\n\n\n

To accomplish this objective, UEFA and Event Merchandising, Ltd. partnered with Anonym<\/strong>, a sophisticated privacy-first data analytics solution harnessed by TikTok to balance campaign performance with user privacy. UEFA leveraged Anonym Private Lift to measure the incrementality (or causal impact) of its three week campaign on TikTok across Europe. All processing occurred in Europe and results were delivered within days of the campaign end. No integration work was required from UEFA or Event Merchandising Ltd. They simply leveraged Anonym\u2019s drag-and-drop interface, ensuring all data was correctly formatted and encrypted.<\/p>\n\n\n\n

The results<\/strong><\/h3>\n\n\n\n

After the campaign ended, Anonym matched hashed and encrypted sales data with hashed and encrypted impression data from TikTok within a confidential computing environment. The data was processed using a differentially private conversion lift algorithm. Differential privacy is a method that makes individual data points indistinguishable and actionable at the same time \u2014 simultaneously enhancing user privacy while allowing effective analysis of ad performance. <\/p>\n\n\n\n

The results were impressive:<\/p>\n\n\n\n
