Google Analytics tracking code

Hi, is there some file where you recommend to insert Google Analytics tracking code?

I would recommend putting the google tracking code in your theme's base.html.twig. So if you were using antimatter that would be:

user/themes/antimatter/templates/partials/base.html.twig

Specifically in the bottom block where the other JS is initializing.

Yes, that seems to be the right place. Thanks.
