What is Google Tag Manager, and How Does it Work? 

What is Google Tag Manager

Successful campaigns begin with prospect information: who is your target audience, and how can you reach them? But, the actions to gain and use that information create trouble for your team and customers. The JavaScript tags let marketers leverage data about their target audience. But as soon as you use it, copying, pasting and creating small-line codes cause another concern when building campaigns and pages. This is where the Google Tag Manager comes to your aid. If you are someone not familiar with it, you would wonder what is Google Tag Manager and how does it works? So, to answer your questions, the blog today will cover the concept of GTM straightforwardly. 

What is Google Tag Manager? 

Google Tag Manager (GTM) is a free tool that lets you efficiently manage tags on the back-end of web pages and simplifies working on them. Users can change and include tags through an inherent interface without needing to manipulate or deploy the code. 

It allows you to track your visitors’ activity on your website and identify the sections on which your visitors are clicking. All tags in a Google Tag Manager are managed in a single place, enabling everyone with the required permissions to download them. 

The Tags are JavaScript and non-JavaScript code snippets code added to a web page as a medium to gather data such as file downloads, clicks, and page views. Google Ads, Facebook, and Google Analytics are sources to tag for digital marketing campaigns. 

There is no restriction on the creation of several tags, and in case a title doesn’t work correctly after streaming life, you can instantly shift to the previous versions performing well. 

How Google Tag Manager Works? 

The Google Tag Manager has its container tag and can be placed on your website if required. This removes the need to put too many codes on a site. After that, the same code is set on every page, so you do not have to rewrite the code for the respective pages. 

Another way you can work with this tool is by tracking what’s happening with your mobile application. It would help if you now used it with iOS, Android, and Firebase SDK. 

Now, despite manually coding tags on your website, use the Google Tag Manager so that they automatically upgrade on the site and don’t need you to put in all those efforts. 

You can also Tag for over one website at the moment so that your task is not restricted to the number of tags you use in a day. All this makes it very easy for you to manage the titles on one or more websites. Even if you work on multiple companies or websites, you must have an account for every business. 

Once you add the code snippets relevant to your application or website, you can link it with the Google Tag Manager. While all this will happen, a web-based interface will then take action to place those codes on the pages. This way, all the tasks are automatically performed for you, and you don’t have to hassle over them. When anything happens, the trigger will be in action. 

Some of the best examples of this event will be if the page loads, a user selects an option, taps on the screen or presses submit on whichever section you have data on your website. Once all such events successfully occur, the Google Tag Manager gathers the information and dispatches it to Google Analytics. 

It will also assist you in handling the tags of your website so that you don’t have to overburden yourself with all the tedious tasks in the series. 

Setting Google Tag Manager for Websites 

It is pretty easy to set Google Tag Manager for websites. All you need to do is build a free and easy-to-set-up account. It doesn’t take much time to set up an account but visit the tagmanager.google.com. After you set your username and password, give a name to the container. Keep in mind the services of your website and the information you are searching for. 

After accepting the terms and conditions, open your website’s HTML section and paste it into the entire code. Because if you do not paste the code correctly, nothing will work properly. 

Setting Google Tag Manager for Mobile Apps 

In this part, the Google Tag Manager functions along with Firebase (a mobile platform for Google applications). It offers the resources you need to set up an account with Google Tag Manager for mobile app. Ensure to sign up for account registration; that is the initial step to setting up a website tool. 

Once again, you must build a container and describe its name. Just ensure to press the mobile app option. It would help if you chose the container type for your mobile application. This can be used with SDK, iOS, and Android versions such as Legacy SDKs and Firebase. 

Two Significant Benefits of Using Google Tag Manager 

There are several Google Tag Manager benefits the GTM tools offer users. They are as follows: 

Site Speed: The asynchronous tag loading and lesser line of code boost the overall speed of the website page. Before the Google Tag Manager, defining event-specific JavaScript code was the only way to track the events. Therefore, many lines of code were needed to track the number of events and drag on the website’s speed. Being a significant ranking factor, the site speed was improved by GTM. 

Less Dependency on Developer: Using the Google Tag Manager minimized the need to involve the developer significantly. You will still need the help of the developer to perform the code deployment process to describe the data layer. GTM tools enable developers to concentrate on vital tasks instead of writing and optimizing the code. 


The GTM tools are undoubtedly free, quick, and easy to track how your visitors use your site. Because it improves the site speed and offers less dependency on developers, consider adding it to your toolbox to know how your visitors engage on the website in real time.
