Which of the following is an example of on-site web analytics?

On-site web analytics refers to the processes and tools used to measure and analyze data collected directly from a website. This typically involves understanding user behavior, traffic sources, and engagement metrics that occur within the site itself.

Using trend-analysis software to analyze server logs is a prime example of on-site web analytics because it directly examines the data generated by visitors interacting with the website. Server logs contain a wealth of information, including details about page views, user sessions, and the paths taken through the site. By analyzing the trends in this data, web developers and marketers can glean insights into how users navigate the site, identify popular content, and detect any issues related to site performance. This information is crucial for optimizing the user experience and improving overall site effectiveness.

The other choices focus on metrics or data collection methods that are either external or not directly linked to user interactions on the website itself. While valuable, they fall outside the definition of on-site analytics.
