Which metric can be enhanced by using secondary dimensions?

The correct choice focuses on how secondary dimensions in Google Analytics provide deeper insights into the data by allowing you to segment and analyze metrics in relation to different attributes of users. The demographic breakdown of users is a metric that can be enhanced through secondary dimensions by letting you view how different demographic segments (like age, gender, or location) interact with your website.

For instance, by applying a secondary dimension to demographic data, you can analyze how various age groups or genders behave in terms of page views or engagement metrics, such as average session duration, providing a more nuanced understanding of user behavior.

In contrast, metrics like average session duration, page views, and new vs returning visitors are primarily aggregate metrics that do not benefit as directly from secondary dimensions in the same way that demographic breakdowns do. They provide overall insights into user behavior without the layered complexity that secondary dimensions add to demographic data.
