Imagine your website is a physical store. Google Tag Manager (GTM) is like an advanced "camera system" that observes visitors when they enter your store and notifies your "partners" (such as Google Analytics, Google Ads, or Meta) about what those visitors do. For example, GTM can simply notify when a visitor arrives or provide more detailed insights, like tracking the areas they visit, the products they view, the items in their cart, or whether they complete a purchase or submit a form. However, it’s important to note that GTM itself does not analyze the data. Instead, it enables the tools you connect to it—like Google Analytics or Facebook Ads Manager—to perform the analysis and give you insights. Think of GTM as the messenger, not the decision-maker. The great part? Instead of installing a separate system for each of your partners, you install one GTM system and configure it to notify all your tools as needed. How GTM Works: Tags: Tags are the connections between GTM and your partners. Each tag sends specific information (like clicks, purchases, or video plays) to tools like Google Analytics or Meta Ads. Triggers: Triggers are the actions you want to monitor, such as a visitor clicking a button, submitting a form, or scrolling down a page. Variables: Variables are like reusable templates or placeholders for information. For example, you can store your Google Analytics ID in a variable and reference it across multiple tags. If the ID changes, you only need to update the variable once, and all related tags will update automatically. To set it up, you install a JavaScript tag on your website. Then, by configuring triggers, tags, and variables, you can track visitor behavior and share that data with the tools you use to analyze it.

GTM is an external tool installed in a website or app that allows you to insert user behavior tracking elements without having to modify the website itself or use a developer to code. It is especially beneficial to non-technical marketing people who can use the pre-defined tags and triggers to monitor, report, and analyze specific events that occur, such as a form submission, add to cart, or a puchase. These events can then be attributed to the traffic source for the website owners to understand how customers find their site and what is generating the leads or purchases.

The first thing to understand about Google Tag Manager is that it consists of three elements—Google tracking tags, triggers, and variables. Marketing tags are tiny snippets of code or tracking pixels from third-party tools like GA4 tracking code, Hubspot, or Adjust’s trackers. Triggers tell GTM where, when, or how to fire, or issue, a tag. Examples include pageviews, form submissions, time on page, and link clicks. Variables add additional information needed for the tag and trigger to work like a page URL, a form ID, or Google Analytics settings.

Google Analytics is a tool that collects visitor data and displays it in various reports, while Google Tag Manager is responsible for activating tools like GA4.

It means you can manage it in one place, and you can roll back to previous versions. You've got kind of version control so you can go and see what is was like before, so it gives you more control. It’s quite a technical tool. It’s not necessarily for everyone, so I’d be a bit cautious with it. The important thing is that that Google Tag Manager code goes on every single page of your website.
