Tesco Media has launched video advertising across its app and Tesco.com to widen brand marketing opportunities within its online grocery journey. The retailer said the app format on its Grocery homepage could reach 12 million monthly unique visitors, while short-form video placements on Tesco.com delivered an average 14% click-through rate to product pages. Tesco added that the ads would be measured through its closed-loop system linking exposure to sales. (Media Leader)
