Many people complain that Google Analytics interface is not very good for examining the flow of user behavior.
It offers the Behavior Flow report in Behavior section. It is a great tool for visualization, but it is a bit hard to work with it.
Luckily, Google Analytics offers more reports. They might seem hidden, but in reality, they are not. You just need to know where to look.
Navigation Summary report
You can find this report in Behavior section, in Site Content and All Pages report. The trick is that you need to change the interface on top, from Explorer to Navigation Summary.
In the Current selection, you can choose any website you want. The report will then show you all Previous Pages, as well as Next pages.
It is also important to note that in Entrances sections, you can see traffic coming from an external source and Exits sections show number of visits with Exits.
Finally, do not forget that the percentages are more important than actual numbers.
