Case Study: Marks & Spencer achieves brand suitability at scale with Zefr

Marks & Spencer achieves zero brand safety violations and 120% overdelivery with Zefr

Marks & Spencer partnered with Zefr to ensure brand safety and suitability for its charitable holiday TikTok campaign. The objective was to drive donations for a Christmas single while reaching a large audience, requiring confidence that their ads would not appear next to unsafe or unsuitable content on the platform.

Zefr implemented its post-campaign measurement solution for TikTok ads to verify brand safety and suitability. The campaign delivered over 17 million impressions, a 120% overdelivery on reach and views, and resulted in zero brand safety or suitability violations. Zefr provided M&S with transparency and peace of mind, allowing them to effectively utilize their budget and optimize performance.
