1) Google Analytics provides various metrics and reports to analyze website traffic and user behavior in context. Pageviews, visits, visitors, time on site, traffic sources, and content reports all provide insights but must be analyzed together rather than in isolation.
2) Pageviews count each page load, visits are sessions between a user and website, and visitors are uniquely identified. Time on site, pageviews, and bounce rates provide different perspectives on user engagement.
3) Traffic source reports show where users come from and which sources drive quality traffic as measured by metrics like bounce rates and conversions. Navigation and entrance path reports help optimize the user experience.
