Google Tag Manager (GTM) is a robust tag management system that has made website tracking extremely reliable and efficient. GTM saves you time, adds scalability to your complex tracking implementation and enables you to keep all your tracking scripts off your website, this significantly reduces any risk of losing analytics and tracking of your campaigns and other important events.
Here are 5 reasons why you should be using Google Tag Manager:
GTM will help speed up many processes. Changes and new tags can be made rapidly and most do not require code changes to the website.
The entire process of implementing Google Tag Manager will also help speed up your site. This is partly due to the fact that GTM loads asynchronously, allowing the rest of the page to load separately.
Two big concerns about maintaining a website are usually security and the possibility of the site malfunctioning. Don't worry! GTM will not crash and mess up with your website, nor will it be the cause for any future vulnerabilities.
You control who has access to your GTM account like Google Analytics, and can revoke access at any time. You'll still need to follow standard security practices with Google Tag Manager, just like you would any content management system or web development tool. There are other benefits like using standardized templates for common tagging scenarios and reducing the potential for mistakes and scripting errors on your site.
Making sure that your tags work before you publish them to the live site is really important. GTM has a built-in debug feature which allows you to personally test each update in your browser on your actual site before publishing the change. This is invaluable to seeing your changes in real-time, without risking the public seeing those changes and without adhering to a rigid development schedule.
Google Tag Manager comes with a built-in version control management feature. Every time you publish a change to a container, it creates a new version, which is archived. If at any time you need to rollback to an existing version, you can do so easily.
This also helps to create a history of what changes were made to the website, when they were published, and who published them.
GTM has a plenty of built-in tags for Google Analytics, Ads conversions, remarketing, as well as many other third-party tags.
Again, you'll benefit from the Google Tag Manager partners and community who are working to standardize various tagging challenges and make it easier to update the tracking on your site.
