(1) Google says "To get all the benefits of Universal Analytics for this property, copy and paste this code into every webpage you want to track."
Does it really go to every webpage I've created (quite a lot), or just site setting > custom code > header, and do it once?
(2) Webflow mentions (https://help.webflow.com/article/integrate-google-analytics-and-mixpanel-into-your-website) that I need to add a footer code. Whereas google doesn't mention this. What does the footer code do and is it necessary? (I have quite a few links)
Thanks in advance.
