How to setup or use Google Analytics?

Question 2: I have placed the google analytics widget in the form, but where and how do find the data in Google anyltics itself? Do i have to set-up something? 

Based from your requirements, I believe you might need a couple of widgets or more tools on how to analyze your visitors activity. But I believe the best widget that you can use is the Google Analytics widget. To add a widget, you can follow this guide. To use it, you'll need to setup a Google Analytics account, from the dashboard there, you can easily see your visitors activity. Here's a link to know more about Google Analytics: https://www.google.com.ph/analytics/.

I hope that helps.
