Why you should use Google Tag Manager
These days more and more people are adopting Google Tag Manager as their preferred way to set up site tracking. In this article, we will provide an overview of what Google Tag Manager is, why you should use it, and how to get started.

What Exactly is Google Tag Manager?

Google Tag Manager is a free tag management system that lets you manage all of your website tags from a single web interface just by adding one snippet of code to your site. But before we go further into Tag Manager, lets talk tags.

Tags are snippets of code that you add to your website to understand user behavior, monitor online advertising campaigns, or measure traffic to your site. Common marketing systems that would ask you to add tags to your site include:

  • Google Analytics – Google Analytics tags track website visitation and user engagement with items on your site like buttons, forms, and more.
  • Google AdWords – Google AdWords tags measure whether users that you are advertising at complete your intended actions, like making a purchase or requesting information.
  • Facebook Advertising – Similar to Google AdWords tags, Facebook tags assess how many users from your Facebook campaigns completed your desired on-site actions.
  • AdRoll Remarketing – Remarketing tags like those used by AdRoll place a cookie on your visitor’s browsers so that you advertise to your website visitors across the web, remaining top of mind.

Managing all these separate tags can be complicated and messy. Cue the awesomeness of Google Tag Manager! Instead of asking your developer to add website tags to your site or messing around with code yourself, you can simply hop into the visually intuitive Google Tag Manager interface and set up tags with just a few clicks. Yes, please!

Why Should You Use It?

  1. Flexibility – as stated above, the core value of Tag Manager is that you can update your website tags quickly and easily, freeing you up to work on more exciting things related to your business!
  2. Plug & Play – Tag Manager comes with a number of pre-built templates, including tags for Google Analytics, AdWords conversions, Remarketing, and other ad networks.
  3. Event Listeners – event listeners make it easy to track Google Analytics events on your site like link clicks, button clicks, and form submissions.
  4. Avoid Redundancy – over time it’s easy for sites to accrue many tags from different sources. Google Tag Manager keeps all your tags organized in one place.
  5. Versioning and Process Control – Tag Manager allows you to create snapshots of the currents state of your tags, so if anything goes awry you can always roll back to a previous version.

Who Doesn’t Need Google Tag Manager?

If you meet both of the following conditions, you can probably skip Google Tag manager:
