Understanding Basic Google Tag Manager (GTM)

Google Tag Manager is a tag management system that enables users to manage marketing tags on websites or mobile apps without changing code. It reduces the need for developers to update tracking codes while making it easy to implement.

To diagnose and improve the effectiveness of tagging, one needs to know the basic elements of GTM along with their interaction. In the coming lines, some critical building blocks of GTM- tags, triggers, and variables-have been discussed.

Core Elements of GTM (Tags, Triggers, Variables)

Google Tag Manager is based on three core elements: tags, triggers, and variables. A comprehension of how these work together is essential to tag management effectiveness.

Triggers

Definition: Definitions of when a tag should be fired.
Purpose: Define the triggers that execute under which conditions
Types: Pageview Click Custom Event Form Submission, to name a few.
Logic Behind Triggers: Triggers will be based upon page URLs that are clicked for elements, from submissions to custom events as well.

Variables

Definition: Placeholder for dynamic values to use in tags and triggers.
Aim: Implement flexibility and dynamism into the tags.
Types include built-in variables, like page URL and click element; user-defined variables, such as custom JavaScript; and data layer variables.
Examples: Product ID, product name, order value, and user ID.

How they work together

Triggers cause tags to fire: If the conditions of a trigger are met, the corresponding tags fire.
Variables provide dynamic data: Variables fill in tag parameters with relevant information.
Tags send data: Once the tag is activated, it sends data to the platform with the variables provided.

Understanding the core elements of GTM lets you establish effective tracking of essential user interactions to gather important marketing data.

Tag Firing Process

Google Tag Manager carries out its tag-firing sequence when users take actions on the page or when pages load completely. Tag Firing has these successive steps to follow:

Trigger Activation:

User interaction with the website or app; conditions set up in a trigger are met.
Trigger becomes active.

Tag Selection:

GTM finds all the tags that belong to the triggered tag.

Variable Resolution:

GTM resolves variables in the tag to replace them with actual values.

Tag Firing:

GTM carries out selected tags to transmit data through determined platforms.

Tag Sequencing:

GTM determines in what order the tags should fire if specified.

Firing Options for Tag

Google Tag Manager (GTM) controls the execution time and behavior of tags through its tag-firing options. The core options include:

Unlimited: Tags fire every time the trigger conditions are met.
Once per event: Tags fire only once for each event occurrence
Once per page: Tags fire only once per page load.

Factors Influencing Tag Firing

The execution of tags depends on various essential variables that include the following:

Trigger priority: Higher priority triggers take precedence over lower priority triggers.
Tag firing order: The tag configuration order can be one of the factors that affect their execution.
Variable availability: The availability of variables will also affect the tags.
Browser settings: Ad blockers or some other browser extensions could also disrupt the firing of the tag.

Understanding tag firing will be well helpful for troubleshooting purposes or when trying to optimize tags. Careful configuration of triggers and tags ensures proper data collection and the effectiveness of marketing campaigns.
