Thank you Tanmay. I was aware of Instances definition. Just wanted to be sure that Next Page Report can only have instances and there is no way to use visits in Next Page Report. Thanks for you reply. Things are clear to me now.

We prefer to use Page name instead of URL to understand the report in easy way. Tons of URL will be slight difficult to understand as which URL belongs to which page. But if use use friendly page name, then it will make more sense while analyzing the report.E.G. www.mysite.com/home can be defined as...

In next page report we get instances as default metric. What is the reason for it? What if I want to see visits metric in next page report.Thanks
