Amazon has introduced a new feature in the Standard Display creative settings of its DSP. This feature allows users to compare creative sizes and supply sources, providing insights on which sizes perform best on specific supplies. The data obtained can guide the creation of creatives based on performance and supply availability across different channels. The goal is to refine and target creatives more effectively at the audience or supply side level, thereby improving ad efficiency. This feature was discovered by the Straight Up Growth = Amazon DSP team.
