If you're tired of calling your developer every time you need to install a Facebook pixel, a Google Ads tag, or a conversion event, this guide is for you.
Google Tag Manager (GTM) is a free tool that allows you to manage and deploy marketing tags on your website without having to constantly modify the source code. It is essentially a smart "container."
Step 1: Create your account and container
Go to tagmanager.google.com. Create an account with your company name and set up a container for "Website." Once you accept the terms, GTM will provide you with two code snippets.
Step 2: Installing the Code
You must paste the first code snippet as high as possible in the <head> section of your site. The second snippet should go immediately after the opening <body> tag.
If you use WordPress, you can use plugins like "GTM4WP" to facilitate this process without touching your theme files.
Step 3: Verify the connection
To make sure everything is working, use the "Preview" function in Tag Manager. Enter your site's URL, and a new window will open with "Tag Assistant." If you see that the container is correctly connected, you're ready to start measuring!
Conclusion
Implementing GTM is the first step toward a serious Growth Engineering strategy. It gives you autonomy, improves your site's loading speed, and allows you to measure every click from your potential customers.
