Here I am trying to add this website "http://www.ngi.ae/" in Google Analytics. For this first I created account and added this website then when I click on audience all figures are displayed as 0. What should I do?

Check this image 2 where audience is 0.

Note: This is not my website/blog. This is another public website like every normal company website have. So I want to fetch data from public websites.
