Understanding your visitors and their actions on your website can help achieve your goals. Google Analytics can take the guesswork out of the equation, bringing you key trends, rich data and actionable insights. The following reports under "Visitors" tab are a great place to start.
- Map Overlay report shows from where in the world your visitors are accessing your site. Hover your mouse over an area to quickly access the metrics associated with that geography. Best of all, you can use the tab at the top to change what metric is used for the map.
- New vs. Returning report shows you a breakdown of visitors into two categories - returning users and new users. You can view through a variety of lenses - total visits, bounce rate, conversions and more.
- Visitor Trending reports overview what your visitors are doing over a period of time. Do my visitors tend to spend more time browsing my site during the week, or on weekend?
