In Google Analytics, what is an objective of setting up conversion tracking?

Setting up conversion tracking in Google Analytics is primarily aimed at measuring specific user interactions that are critical to the goals of a business or website. By establishing conversion tracking, you can identify which actions users take that lead to desired outcomes, such as completing a purchase, signing up for a newsletter, or filling out a contact form. This level of measurement enables businesses to assess the effectiveness of their online strategies, understand user behavior, and allocate resources more efficiently towards activities that drive meaningful engagement and return on investment.

The other options, while relevant to website analytics, focus on different aspects of data analysis rather than the core purpose of conversion tracking. Total page views provide information about website traffic but do not indicate whether users are engaging in valuable actions. Optimizing user interface design is about improving user experience and layout, which does not directly relate to tracking conversions. Analyzing traffic sources is essential for understanding where visitors are coming from, but it does not specifically measure interaction outcomes tied to conversions. Thus, option B stands out as the fundamental objective of leveraging conversion tracking in Google Analytics.
