Final answer:
Web analytics typically include data on returning users, the average time spent on pages, and which pages users view before leaving the site, focusing on user behavior and website optimization rather than personal details.
Step-by-step explanation:
The web analytics of a website can provide a wealth of information to website owners and marketers about their visitors' behavior. Importantly, web analytics focus on data that can help understand and optimize web usage, rather than collecting personal information like home addresses or dates of birth, which would not be ethical or legal to track without consent.
Among the data that web analytics may include are: how many visitors were returning users who have visited the site previously; this helps understand user loyalty and engagement. Another key metric is the average amount of time users spend on a particular page, indicating the content's appeal and relevance. Lastly, it is common to track which pages users were typically viewing when they left the website, as this can pinpoint areas where the site may not be meeting user needs or areas that could be causing users to leave.
Overall, web analytics are a powerful tool for improving website performance, providing insights into how users interact with the site, rather than collecting sensitive personal information.
