Browser tracking refers to the methods used by websites and advertisers to collect data about users' online activities. This can include tracking the pages you visit, the time spent on each page, and your interactions with ads. The information gathered helps companies understand user behavior and preferences, allowing them to tailor content and advertisements to individual users. There are various techniques for browser tracking, such as cookies, web beacons, and fingerprinting. Cookies are small files stored on your device that remember your preferences, while web beacons are tiny images embedded in web pages that track user activity. Fingerprinting involves collecting unique information about your device to identify you without using cookies.
