Third-Party Cookies
Cookies set by domains other than the website the user is currently visiting, typically used for cross-site tracking and advertising.
Third-party cookies are placed on a user’s browser by a domain different from the website they are visiting. For example, when you visit a news site, an advertising network embedded on that page may set its own cookie to track your browsing habits across multiple websites. These cookies enable cross-site tracking, retargeting ads, and building detailed user profiles without users necessarily knowing which companies are following their activity.
Third-party cookies have come under intense regulatory and technical scrutiny. Privacy regulations like the GDPR require explicit consent before setting these cookies, and browsers like Safari and Firefox already block them by default. Google Chrome has also been moving toward phasing them out. This shift is pushing the advertising industry toward privacy-preserving alternatives like contextual advertising and first-party data strategies.
