What is Google Tag Manager

Google Tag Manager is a free tool for managing tags on a website. We can easily add, modify and remove them from the site and more effectively analyze website data, track conversion growth and traffic sources.

GTM components

Google Tag Manager consists of 4 basic elements: tags, containers, rules and variables.


Tags, which are JavaScript codes, send information about website traffic and user behavior messages so that they can be updated and detailed data can be collected and submitted to Google Analytics.

We could think of them as small pieces of JavaScript code that we can add with most functionality to our website.

Tags are responsible for collecting data correctly where they are placed and are an integration (such as between our site and Facebook).


The collection of tags and scripts is contained in a container. GTM tool experts usually advise using the principle of one container for one site. Then there is no doubt what exactly our container supports.


Rules are elements that are responsible for determining when a predetermined tag should be called.

If we want our website to display a thank you message when a customer makes a purchase, this is an example of a rule based on which Google Tag Manager calls the tags.

There are many examples of ready-made rules, such as: opening a page, clicking on a link, a timer, clicking on an element on a page, scrolling through a page or submitting a form


Variables are information that are used in tags or events.

Who is GTM for?

The tool is user-friendly and recommended for any analyst, online store owner, website data person, in other words, anyone interested in analyzing and influencing the improvement of user experience. Responsive site actions and smart, thoughtful rules make it easier and more enjoyable for users to use sites.

Many advantages, 0 disadvantages


Simple, intuitive and easy to use – these are the most important advantages of Google Tag Manager. No one now has time to create long javascript codes, correct them, learn how to code, send them to an IT specialist and wait for feedback from him. With tags, every website owner will learn how to use the tool and add tags on their own.


You don’t have to know coding and programming, let alone call your IT guy every time you want to make a change to your website. You don’t have to wait weeks for feedback from your IT department. You can manage the tags yourself, and without setting up a ticket (and without waiting for it to be processed).

Analytics at your fingertips

With Google Tag Manager, you have access to a professional tool at your fingertips – without the need for a programming degree, expensive IT courses or hiring a Google analyst. You won’t need expensive and complicated programs or expensive hardware either.

Oh, did we mention that Google Tag Manager is a free tool?


Adding, changing and deleting tags are typical tasks that can be done as ASAP as possible 🙂

If you are the tag manager and you care about time and changes, get started right away. You don’t have to explain any more to the programmer what you actually mean, you just get to work right away with the tool. And you get the results right at the press of an entera.

Preview and correction at once

Among the most important features of Google Tag Manager, according to users, is the ability to see the results of your work right away, but not necessarily implement them yet. With the tool, it’s easy to preview how it all works, see if the effect is satisfactory. If not, we make corrections. And then more. Finally, if everything is ok, you can fire up the tag and observe its impact on our site.


Using GTM we save time – we make changes immediately and independently, and we see the effects immediately. We also make corrections on the spot.

The savings are also financial – we do not hire a programmer to implement the changes. We transform ourselves into an IT employee.


If we are not sure if a particular tag is useful to us or not, or we are checking it all the time, we can temporarily disable it and enable it again after some time without making a revolution.


Working on our own site and having a real impact on its “behavior” can give a lot of satisfaction and pride. We gain new competencies and develop our skills.

If you want to take control of your website, have savings and satisfaction at the same time, get interested in the tool and the benefits of Google Tag Manager – simple, functional and easy to learn even for non-programmers.
