First-Party Data Strategies in a Cookieless World: Practical Steps for Retailers

As the era of third-party cookies draws to a close, retailers face a pivotal moment in how they understand, engage, and serve their customers. The shift to a privacy-first digital landscape is not just a compliance challenge—it’s a strategic opportunity. By building robust first-party data strategies, retailers can unlock deeper personalization, drive customer loyalty, and maintain marketing effectiveness, all while respecting consumer privacy.
