First-party cookies

What is a first-party cookie?

First-party cookies are stored by the domain a user visits and help websites remember user preferences, login details, and shopping cart contents. Unlike third-party cookies, they are considered more privacy-compliant as they do not track users across multiple sites. Advertisers leverage first-party data for personalized targeting and improved customer experience. Want to understand how first-party cookies impact digital marketing?
