Where is the right place to insert the Google Analytics code on the Bitrix website?

Question

Google Analytics

On the site, the last developer left a wild dump, found a bunch of different template folders, where what is responsible for what and where it is displayed, try to figure it out. What is a 100% way to put code in the footer to make it work?

Answer 1

/bitrix/templates/#template name#/footer.php

Answer 2

Just take it and paste it into the footer.php file of your template. Nothing more needs to be done.
Well, or if you want more flexibility, then create a file with such scripts and do it through the include area also in the footer
