Third-party cookies play a crucial role in native advertising by enabling user tracking, audience targeting, and ad personalization across websites. These cookies are placed by domains other than the one a user is visiting, allowing advertisers to collect behavioral data, such as browsing history and interests. This data helps build detailed user profiles, enabling more relevant and personalized display ads, which improves click-through and conversion rates. Third-party cookies also support retargeting campaigns, where users are shown ads for products they previously viewed. However, increasing privacy concerns and regulations, like GDPR and browser restrictions, are phasing out third-party cookies. This shift challenges advertisers to find alternative tracking methods, such as first-party data and contextual targeting, while maintaining ad effectiveness and user trust.
