5 Install Google Tag Manager
I am going to make the assumption that you have chosen for and are ready to install Google Tag Manager (disclosure – author works at Google). The first step is to log in to Google Tag Manager using your Google account. You should see this the first time you log in.
If you insert the company name you are looking to set Google Tag Manager up for, you are then asked to name you first container and where you will be running this container. I have named the container “all pages” after the trigger that I will use. Every website should have an “all pages” container as there are always several tags that need to be deployed on all pages of your site.
After agreeing to the terms and conditions I then get the code for Google Tag Manager. To implement Google Tag Manager, copy the code snippet provided in the Tag Manager interface or from the notification (you get if you click on the blue create button) below, replacing both instances of GTM-XXXX with your container ID. Paste this snippet into your website template page so that it appears immediately after the opening
<body> tag. Or alternatively, if you are using one of the big CMS out there, you can use the GTM account number (grey-ed out below) to insert into your plugin.
Plugins for WordPress, Joomla & Drupal sites
Are you using one of the large content management systems? This site uses WordPress and thus a WordPress plugin for Google Tag Manager. Drupal and Joomla have the same plugin available. Together, these three content management system cover eighty five percent of the websites out there. Most other tag management solutions have plugins available for the large content management system.
Whatever plugin you use, it can place the necessary container code snippet into your website so that you do not need to edit your theme files. So there is no need for developers whatsoever to realise a Google Tag Manager (GTM) implementation.
It is as simple as that.
Code implementation of Google Tag Manager
You could also install Google Tag Manager code on each of your pages. Or drop it in a page template for example. You paste the Google Tag Manager snippet into your website template page so that it appears immediately after the opening
<body> tag. You can read all about how to do that in the quick start guide.
