For instance, third-party analytics cookies analyze how visitors interact with Microsoft websites to enhance user experience. Among the functions of these cookies, they track page visits and the number of clicks needed to complete specific tasks. Microsoft’s approach to advertising is multifaceted. They create user profiles based on browsing activity, which then informs how ads are targeted. For example, 512 partners build profiles that reflect users' interests and personal characteristics based on their online activity. This profiling is not limited to ads; it extends to content personalization as well, with 198 partners adjusting what non-advertising content is presented to users based on their preferences.

For example, they measure whether users click on ads or how long they spend reading articles. This data is crucial for refining advertising strategies and ensuring that the content shown aligns with user interests. Overall, the extensive data management practices reflect a broader trend in digital marketing aimed at maximizing user engagement through targeted content.
