I know that I can create one Analytics account, and add Filters for individual domains (http://domain1.com, [domain2.com,
...] domain3.com etc). When I log in to Google Analytics I go to -> Admin, and -> +New Account. I need to enter a Website Name, Website URL, and Account Name. What URL should I use if this account is suppose to work with multiple domains and not just one. It would be probably best if I could leave it blank, but there is no way to do that. Or maybe there is a different way to set up a website network Google Analytics account?
