What is a possible use of the 'Goals' feature in Google Analytics?

The 'Goals' feature in Google Analytics is designed specifically to measure conversions based on user-defined criteria. This functionality allows users to determine whether their website is fulfilling its objectives, such as completing a purchase, signing up for a newsletter, or reaching a specific page. By defining goals, businesses can analyze user behavior and understand how effectively their website converts visitors into customers or leads, offering insights into overall performance as well as the effectiveness of various marketing efforts.

The other choices do not align with the primary purpose of the 'Goals' feature. Setting alerts for server downtime falls outside the scope of goals, as it pertains more to website reliability and uptime monitoring rather than user actions or conversions. Tracking the number of ads clicked is related to measuring ad performance, which is typically managed through other reporting tools rather than goals. Deleting outdated data is a data management task rather than a measurement of user interactions or conversions, which is the essence of the Goals feature in Google Analytics.
