Google Tag Manager is an efficient way of dynamically managing tagging on a website from Google. Instead of adding tracking code from multiple sources (eg Google Ads, Facebook, Twitter etc), you simply add Google Tag Manager to your site and then add the 3rd party codes to GTM.
Google Tag Manager allows you to manage which tags load on which pages and why. It’s honestly a real lifesaver for people who need to add code to their site, but don’t want to be constantly messing with the code of their site.
