What is the "Cohort Analysis" report used for in Google Analytics?

The "Cohort Analysis" report in Google Analytics is specifically designed to examine user behaviors and conversion patterns across different user groups over time. This report allows analysts to group users based on shared characteristics or experiences (such as the time of their first visit) and track how these groups behave, including metrics like retention rates, conversion rates, and engagement over specified periods.

Cohorts can be particularly useful for understanding the impact of changes made to the site, marketing efforts, or the introduction of new features. By analyzing how different cohorts respond to these changes, businesses can gain insights into user retention and the value of specific segments of their audience. This dynamic perspective enables more informed decisions regarding marketing strategies and user experience enhancements.

Other options relate to aspects of analytics that do not encapsulate the core purpose of Cohort Analysis. While comparing site performance to industry standards is valuable, it falls under benchmarking rather than user behavior assessment. Assessing financial impact and measuring bounce rates are also focused on performance metrics rather than the time-based behavioral analysis that Cohort Analysis provides. Therefore, C stands out as the correct choice, as it accurately describes the intended use of the report in understanding user engagement over time across different groups.
