Webtrends Tagging Deployment Options
With this option, the extension is automatically added to all modern pages in the tenancy when uploaded to the app-catalog.
As of the V3.0 release, Webtrends Tag Manager also supports a non-tenant wide deployment option allowing tagging of specified site collections without adding the extension to all modern pages in the tenancy. This version installs the Webtrends Tag Manager package to the desired sites, which adds the extension to all modern pages and the User Custom Action to all classic pages in just that site. The package can also be installed onto sub-sites within the site collection depending on the configuration of thesub-site depth option found in the web part side panel.
With this option, the extension is not installed to any sites when uploaded to the app-catalog. An Administrator must use the web part UI to install the package to the desired sites individually.
Webtrends also provides separate Add-in and App Extensions which can be deployed on a per site collection scope and and configured on each site rather than in a centralized location.
