The Google tag (gtag.js) is a single tag you can add to your website to use a variety of Google products and services (e.g., Google Ads, Google Analytics, Campaign Manager, Display & Video 360, Search Ads 360). Instead of managing multiple tags for different Google product accounts, you can use the Google tag across your entire website and connect the tag to multiple destinations.
