I can't figure out how to add the code to the site. I've put the code in the template, but the templates aren't updating on the pages unless I open them individually and save them. There are hundreds of pages on the site! Do I really have to open and save hundreds of pages just to be able to use Google Analytics? What if I need to make changes to my metrics later?! Will I have to do this every time I need to update the Google JS? Please help.
