gtag vs Tag Manager

Last Updated: 2022-03-25

gtag (global site tag) and Tag Manager are two Google products that can help you track the traffic to your websites or mobile apps.

Key difference:

  • gtag: aggregate all tags for google products (ads, analytics)
  • Tag Manager: not limited to Google products, can also include Facebook Pixel or any javascript based tool that has a tracking code you can install.

Tag Manager is much more powerful; gtag is essentially a mini versin of Tag Manager, good for beginners.
