Custom Metrics can be applied at which scopes?

Custom Metrics in Google Analytics can indeed be applied at the hit scope level. This means that these metrics are designed to track specific interactions and behaviors that occur on individual hits, such as page views, events, or transactions. When you set a Custom Metric at this scope, the metric will record data specifically related to that single hit, providing granular insights into user interactions.

Custom Metrics can also be set at other scopes, including session, user, and product levels, which allows for more comprehensive data analysis. However, the question specifically asks about the scope at which Custom Metrics can be applied, and the correct interpretation leads to hit scope since it directly relates to measuring specific actions in real-time, making it essential for understanding user engagement at a detailed level.

Understanding the different scopes is crucial for effectively leveraging Google Analytics to gather insights that can help with decision-making and optimizing marketing strategies.
