What Is Google Tag Manager? (And How Does It Work With Google Analytics?)
Google Tag Manager (GTM) is a tag management system (TMS) that allows users to easily add and edit snippets of custom or templated code--called tags--to a website. Tags can add analytics tracking, manage advertising pixels, or create additional site functionality. GTM includes dozens of predefined tag templates requiring no custom coding.
How GTM Works with Google Analytics
For quite some time, Google Analytics (GA) has been around to help you collect, process, configure, and report website and mobile app data that results in actionable insights. Then in 2012, Google announced the release of its new groundbreaking product, known as Google Tag Manager (Tag Manager or GTM).
In short, we love it. And we write about it often! Despite GTM’s usefulness, there’s still a lot of confusion about what it is, what it does, and how it’s different from Google Analytics. So, we’ve decided to dedicate this bit to dissolve the confusion.
Where People Get Tag Manager Wrong
A common misconception is that Tag Manager is the same thing as (or the latest version of) Google Analytics. This is not the case! In actuality, Google Tag Manager is a completely separate tool.
Breaking It Down
Google Tag Manager consists of these three main parts:
- Triggers: Defines when and where tags are executed.
- Variables: Used to receive or store information to be used by tags and triggers.

Where Should the Google Tag Manager Snippet Be Placed?

Most importantly… You can take tagging into your own hands, and steer your tracking however you desire, quickly and easily, without those sometimes pesky backseat drivers (your developers).
So GTM And GA Aren’t An Old Married Couple?
Not necessarily. Google Tag Manager and Google Analytics are two completely separate tools, and can live independently of one another: You can use Google Analytics on your site by itself, just as much as you can use Google Tag Manager on your site by itself.
However, as our Technical Marketing Manager, Jon, always says, “Google loves Google.” Therefore, it shouldn't be surprising that they work very well together.
GTM And GA Working Together
Quite honestly, the possibilities of how the two tools work together are endless!
Here’s an example:
For Google’s sake, we’ll show you how to send data to Google Analytics using Tag Manager. Let’s say that you need to track resource downloads on your website (pdfs, docx, xls). For tracking purposes, it’s important to know two things:
- How many people downloaded the file?
- What page was the user on when it was downloaded?
In this case, GTM allows you to easily set up a Click Trigger and a Google Analytics Tag to see what and where resources are being downloaded without needing to add any additional code to your site.
Furthermore, you can use Google Tag Manager triggers to dictate when this data should be sent to Google Analytics. To expand on our previous example, maybe you want to only send a virtual pageview to Google Analytics when a user clicks on a resource download link. If so, you can use Tag Manager’s triggers to specify these conditions.
Seven Reasons Why Google Tag Manager Is Special
1. It’s F-R-E-E, Free.
Not to worry, it’s both free and awesome! Google Tag Manager has a multitude of robust features, including (but not limited to) usability, accounts and user roles, tag firing rules, and supported tags (Google, third-party, and custom HTML tags).
2. Do It Yourself
Insert the container tag once, make changes whenever you want without much hassle, and voilà! With the available debugging tools and preview mode, you can be sure of what you’re doing before you publish it.
3. Forget About Limitations
You can use Google Tag Manager with more than just Google products. Take a peek at the other predefined tags, such as Marin, comScore, AdRoll, and more! Can’t find the tag you need? Customize one! You can also add Tag Manager to not only your website, but also to your iOS and Android apps. You’re truly unlimited.
4. Cool Features With Google Analytics
Google Tag Manager makes it easier to implement some of the more complicated Google Analytics features, such as User ID tracking. User ID tracking gives you the ability to measure real users instead of devices. This provides more accurate data for you, which ultimately helps your users! It’s a win-win. Tag Manager also helps with common challenges in Google Analytics, such as Custom Dimensions, Cross-Domain Tracking for multiple sites that are tracked together in Google Analytics, and Enhanced Ecommerce that requires collaboration with developers.
5. Easily Track More Things
6. Worry-Free Security
No need to worry. Google Tag Manager has all of the security features you need. One awesome feature is two-factor authentication that requires both your normal password and then a numeric code that you receive via a text message, voice call, or mobile app. You are also able to control the access by granting different levels of permission at both the account and container levels.
7. Debug Central
With debug options, built-in error checking, and version controls, you can rest easy knowing that everything you do with Google Tag Manager can be tested and debugged before it goes live.
