Google Tag Manager allows you to quickly and easily update
- Tags on your website (such as tracking and marketing optimization tags). You can add and update AdWords, Google Analytics, Floodlight, and non-Google tags from the Google Tag Manager user interface instead of editing site code. This reduces errors, frees you from having to involve a webmaster, and allows you to quickly deploy tags on your site.
- The configuration and flag values of mobile apps that you have created. Instead of rebuilding and deploying new binaries, you can use the Google Tag Manager interface to change configuration values (for example, timeout, ad position, game play dynamics) and turn on flag-enabled features in your mobile apps.
