A tag is snippet of JavaScript that sends information to a third party, such as Google. Tags collect data, target your ad campaigns, track ads, and perform other functions. The Analytics tracking code is an example of a tag. If you don't use a tag management solution such as Google Tag Manager, you need to add these snippets of JavaScript directly to the source code of your site.
