Reuse configuration settings in Google Tag Manager

This page is for users who maintain their Google tag in Google Tag Manager and want to define shared configuration settings that are valid for multiple Google tags.

What is a configuration settings variable?

You can reuse configuration settings across several Google tags using a Google tag: Configuration settings variable. For example, let's say you publish your website in multiple languages, and want to segment your audience according to the language they read in. You can create a configuration variable with a language parameter and use it across your Google tags, instead of manually updating each tag.

How to set up a configuration settings variable

To create a new configuration settings variable:

  1. Open Google Tag Manager
  2. In your workspace, open the Variables menu on the left.
  3. Create a New user-defined variable.
  4. In Variable Configuration, select the Google tag: Configuration settings variable.
  5. Add the parameters you want to reuse. You can find a table of pre-defined parameters below. If none of these fit your needs, you can always create a custom parameter. Just type a name of your choice in the Name field.
  6. Name your variable and Save.

content_group string undefined Content groups let you categorize pages and screens into custom buckets. Learn more about content groups.   x  
conversion_linker boolean
Use this parameter to opt out of conversion linking for Ads and Floodlight. When set to false, you can opt-out of conversion linking. x    
cookie_domain string
Specifies the domain used to store the analytics cookie.
To set the cookie without specifying a domain, set to 'none'.
Set to 'auto' (the default value) to set the cookie to the top level domain plus one subdomain (eTLD +1). For example if cookie_domain is set to 'auto' would use for the domain, and would also use for the domain.
x x x
cookie_expires number
Every time a hit is sent to Google Analytics, the cookie expiration time is updated to be the current time plus the value of the cookie_expires field. This means that if you use the default value time of two years (63072000 seconds), and a user visits your site every month, their cookie will never expire. If you set the cookie_expires time to 0 (zero) seconds, the cookie turns into a session based cookie and expires once the current browser session ends. Caution: If you set the cookie to expire too quickly, you will inflate your user count and decrease the quality of your measurement. x x x
cookie_flags string undefined Appends additional flags to the cookie when set. Flags must be separated by semicolons. See write a new cookie for some examples of flags to set. x x x
cookie_path string
Specifies the subpath used to store the Google tag cookie. x x x
cookie_prefix string undefined Specifies a prefix to prepend to ads and analytics cookie names. For example, you can rename ads cookies starting with _gcl_aw to <your-prefix>_aw. x x x
cookie_update boolean
When cookie_update is set to true:
  • GA4 and Merchant Center update cookies on each page load. This will update the cookie expiration to be set relative to the most recent visit to the site. For example, if cookie expiration is set to one week, and a user visits using the same browser every five days, the cookie expiration will be updated on each visit and will effectively never expire.
  • Ads and Floodlight update cookies with the original expiration date, so it is still relevant to the first visit.
When set to false, cookies are not updated on each page load. This has the effect of cookie expiration being relative to the first time a user visited the site.
