What type of data is described as being gathered by user behavior?

The correct choice is implicit data, which refers to information collected about users based on their behavior, preferences, and interactions. This type of data is gathered passively, often without the user explicitly stating their preferences or providing direct input. Examples include tracking a user's browsing history, clicks on emails, time spent on pages, and engagement with specific content. This behavior-driven data is valuable as it provides insights into user interests, habits, and patterns, helping marketers to personalize communication and improve user experience.

In contrast, explicit data encompasses information that users intentionally provide, such as survey responses, contact forms, or preferences they set. Static data refers to fixed information that doesn’t change frequently and usually includes details like names and addresses. Transactional data is related to specific transactions or interactions, such as purchase history or service requests. Each of these types of data serves unique purposes, but implicit data stands out for its ability to reveal insights based on observed user behavior.
