Ecommerce's rapid growth during the pandemic has spurred the rise of retail media networks, which leverage consumer data to create targeted advertising opportunities for brands. These networks function similarly to advertising businesses, allowing brands to purchase ad space on retailers' online platforms, thus hastening the conversion from ad exposure to sales and providing clear attribution metrics. As third-party cookies are phased out, retailers' first-party data becomes increasingly valuable for personalized marketing, enhancing brand loyalty and enabling upselling and cross-selling strategies. With significant market potential, retail media spending is expected to grow substantially, driven by major retailers like Walmart, Target, and Home Depot, who are developing their own media networks to capitalize on this trend. Aerospike supports these networks by providing a robust data infrastructure that enhances recommendation engines, user profiling, and data management, ensuring secure, scalable, and efficient operations.
