How to Use Google Tag Manager?
Login with your existing Google account into Tag Manager
Enter the account name. In most cases, it's your company name.
Create a container for your domain name. A container is the place which holds all the individual tags of your website.
Get the container snippet code generated automatically by Tag Manager and paste in on your site below the opening <body> tag.
Start adding tags on the site container. You can add both Google and Non Google tags on your container. For example, if you want to use the Google Analytics tag on the site, then go to "add new tag" under the tags tab. Enter tag name as "Google Analytics", choose "Google Analytics" under the tag type drop down menu. Enter the web property id, add a rule for the tag (in this case it would be "all pages" as we need to track visitor data from all the pages of your site. Save and its done.
