Google Tag Manager, or GTM, is a free tool that makes it easy for marketers to add and update website tags—including conversion tracking, site analytics, remarketing, and more—with just a few clicks and without needing to edit your website code.

A tag is a snippet of code that sends information to third parties. Tags are used for marketing and analytics, like tracking conversions or remarketing. Previously, adding and updating these tags was a big challenge for marketers—it meant asking developers for help whenever new tags were needed or updates had to be made. If a developer made an error in the coding process, it could cause bigger problems on the site.

For marketers with limited coding experience, this can be a game changer. Before GTM was around, you'd usually need to work with your web developers to make even the smallest tag changes. Now, you can add and update tags for conversion tracking, site analytics, remarketing, and more—all without needing help from your IT team or webmaster.

Here are some benefits of using Google Tag Manager.

• GTM gives marketers more agility and control over how tags are fired across their sites. They can make updates in real time, instead of waiting weeks or months for developer resources to become available. It's also easier to test and deploy new tags because you can do so without disturbing any code currently on your website.

• GTM makes it simple for marketers to manage their tags and track their website visitors' behavior across a variety of devices. This allows marketers to measure important metrics like site analytics, conversions, and remarketing goals—all in one place.

• Another benefit of using Google Tag Manager is that it allows you to deploy tags across multiple websites from a single interface. This can save you a lot of time if you manage multiple websites, as you will only need to update the tag manager container instead of each individual website.

• Finally, Google Tag Manager can help reduce errors on your website, as it will automatically test and debug any tags that are added before they are deployed live. This means that there is less chance of something going wrong when adding or updating tags, which can save you a lot of time and frustration in the long run.

Overall, Google Tag Manager can save time and make managing your website or mobile app's tracking and advertising easier.
