The Active Users report provides insights into which aspect of user interaction over time?

The Active Users report specifically focuses on user retention by tracking the number of users who engaged with the website or app within a specified time frame, such as the past day, week, or month. This report provides insight into how many users return to the platform after their initial visit, allowing businesses to measure the effectiveness of their efforts in not just attracting visitors but also retaining them over time. By analyzing this data, organizations can assess user loyalty and identify patterns that may influence retention strategies.

Regarding the other options, while total number of visitors is important, it does not provide the same depth of insight into user behavior over time as the Active Users report does. User engagement on social media is also valuable but falls outside the scope of what the Active Users report tracks, which is strictly focused on direct application interactions. Lastly, return on marketing investment is a financial metric and does not directly relate to user interaction insights in the same context as retention behaviors. Thus, the choice of user retention accurately captures the core aspect of the Active Users report.
