Gary Milner, Director of Global Digital Marketing Strategy at Lenovo, discusses using real-time bidding (RTB) to unify Lenovo's brand. He argues that RTB can help reduce wasted media spending, drive creative efficiencies through testing, provide immediate scale with transparency and brand safety, and allow Lenovo to respond quickly to changes. Milner provides examples showing how RTB can lower campaign costs and dynamically optimize ads to improve metrics like completion rates and shares.
