gtag.js

Websites need a snippet of JavaScript code (called a "tag") on each page in order for the reports in your Analytics property to show data. If you set up Analytics on your site during August 2017 or later, your site is probably tagged with gtag.js (also called the global site tag). If you set up Analytics on your site before August 2017, your site is probably tagged with analytics.js.
