<div class="alert">
When you install this version of Matomo Tag Manager, users with admin access will be able to create custom HTML tags, triggers, and variables that may execute JavaScript on your website. These custom templates could be misused to steal for example sensitive information from users (known as <a href="https://en.wikipedia.org/wiki/Cross-site_scripting">XSS</a>). You can disable these custom templates under "Administration => General Settings". We will later have new permissions in Matomo that allow you to configure who will be able to use these kind of templates.

Matomo Tag Manager lets you manage and unify all your tracking and marketing tags. Tags are also known as snippets or pixels. Such tags are typically JavaScript code or HTML and let you integrate various features into your site in just a few clicks, for example:

* Analytics
* Conversion Tracking
* Newsletter signups
* Exit popups and surveys
* Remarketing
* Social widgets
* Affiliates
* Ads
* and more

It makes your life easier when you want to modify any of these snippets on your website as you will no longer need a developer to make the needed changes for you. Instead of waiting for someone to make these changes and to deploy your website, you can now easily make the needed changes yourself. This lets you not only bring changes to the market faster, but also reduces cost.

For example want to track an event into your Matomo whenever a certain button is clicked? It will take you only a few clicks to get the insights you need when you need them which in return lets you make decisions faster.

Matomo Tag Manager also comes in handy if you embed many third-party snippets into your website and want to bring in some order to oversee all the snippets that are embedded and have a convenient way to manage them. It also makes sure all that all snippets are implemented correctly and improves the performance of your website.

If you have different environments for your website or platform or want to test new changes before making them available globally you will be please to hear that we have you covered. With a click of a button you can deploy your tags to an environment of your choice.

Last but not least Matomo Tag Manager keeps track of all changes that you make and lets you restore snapshots at any given time.
