Cookie

A Cookie (specifically an HTTP cookie) is a small text file that a website stores on a user's computer or mobile device through their web browser. Cookies are used for various purposes, including remembering login information, tracking user preferences, maintaining shopping cart contents, and collecting data about user browsing behavior for Analytics and targeted advertising. In advertising, third-party cookies have been widely used for Behavioral Targeting, Ad Retargeting / Remarketing, and measuring Campaign effectiveness across different websites. Due to privacy concerns, the use of third-party cookies is declining, with a shift towards first-party data and other tracking methods.
