This article is about Google Analytics 4 properties. Refer to the Universal Analytics section if you're still using a Universal Analytics property, which will stop processing data on July 1, 2023 (October 1, 2023 for Analytics 360 properties).


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 your site prior to August 2017, your site is probably tagged with analytics.js.
