Thus, you cannot create a tag without a trigger. A trigger can take the value “true” or “false”. It is executed only if its value is true and if all the conditions of the trigger are met.
And to determine this (true or false), the value of the variable is compared to the one set in the trigger. All triggers in Google Tag Manager are event-related. They may also have additional conditions or filters. In the old version of Google Tag Manager, a trigger was called a “rule”.
