Cookie-Based Tracking
Cookie-based tracking is a web technology method that uses HTTP cookies to collect and store data about user interactions and behavior on websites. It involves placing small text files (cookies) on a user's device to track activities such as page visits, session duration, and preferences. This data is commonly used for analytics, personalization, and targeted advertising across web sessions.
Developers should learn cookie-based tracking when building websites or applications that require user session management, analytics, or personalized content delivery. It's essential for implementing features like shopping carts, login persistence, and behavior analysis in e-commerce, marketing platforms, and content sites. However, it's increasingly important to understand its limitations due to privacy regulations like GDPR and browser restrictions.
