Cross-site tracking refers to the practice of monitoring and recording a user’s online activity across multiple websites or platforms. This is typically done through the use of cookies or other tracking technologies, allowing companies to gather information about a user’s browsing habits and interests. While this can be used for targeted advertising and personalization, it also raises concerns about privacy and data security. Cross-site tracking can be used by both legitimate businesses and malicious actors, making it important for users to be aware of and take steps to protect their online privacy.
