Organizing Your Containers
How many accounts and containers do I need?
Most businesses will have one account for all of their containers.
In most cases you will want to have one container for each website or mobile app.
For example: Your company might have an information website, and ecommerce website on a separate domain, another domain that is hosting a blog, and a mobile app for Android and for iOS. In Google Tag Manager, they have it set up so there is one corporate Tag Manager account, and within that account they have four containers set up: one container for each of their web properties, a container for the Android app, and a container for their iOS app.
Important note for mobile apps: Each new major version of a mobile app should have a new container. (Minor revisions such as bug fix releases might not need new containers.) Use container export/import to migrate content between containers.
Use Folders to Organize Content
Tags, triggers, and variables created in Google Tag Manager can be organized into folders. Folders can help organize your container items by project, by category, by workgroup, and any other way that you like.
Tag Naming Conventions
It is likely that you may end up creating multiple Google Analytics, DoubleClick Floodlight, AdWords, and other tags. To keep things organized and easy to locate, we recommend using a naming convention similar to the following pattern: <tag type> - <name of app> - <detail>. To learn more, please read Naming conventions and setup tips.
Ultimately the naming convention you use is up to you. We recommend keeping it consistent for your organization and well documented so everyone involved knows what to expect.
Managing Container Size
Over time, the number of tag, triggers, and variables in your containers may grow. In order to keep your workspace manageable and to keep the size of your container under control, remove unneeded items from your container and look for efficient ways to manage and consolidate your container content. If you have items that are no longer in use or needed, see if you can delete them from your container. If you have multiple tags performing very similar functions, see if there is a way to consolidate their functionality into a single tag.
