Which of the following is considered a manual metric?

Revenue is considered a manual metric because it typically requires more intervention to track accurately. Unlike some automatic metrics derived from user engagement data, revenue often involves calculating total sales from various sources, including e-commerce platforms, accounting systems, or financial reports. This process demands manual input to account for returns, discounts, and overall sales performance, making it a more complex and less automated metric compared to the others listed.

For instance, while pageviews, sessions, and time on page are automatically tracked by analytics tools, revenue necessitates periodic reviews of sales data, adjustments, and reconciliations to provide an accurate financial overview. This level of detail and manual oversight differentiates revenue from the other metrics, which are primarily calculated based on direct user interactions tracked in real-time by web analytics systems.
