First-Party vs. Third-Party Cookies: Key Differences and Implications First-party and third-party cookies play distinct roles in the online experience, particularly in marketing and user engagement. While they share some similarities, their creation, functionality, and reputation differ significantly. What Are Cookies? Cookies are small data files stored on a user’s device to track activity and save information from a website visit. They enhance browsing by personalizing experiences—for example, saving login credentials, remembering preferences, or enabling targeted advertisements. When a user inputs their ZIP code to check the weather or adds items to a shopping cart, cookies store this information for future convenience.
