# UTM Tracking Basics

Why UTM tracking matters and how Molecule Data uses it.

{% hint style="info" %}
**IMPORTANT:** Accurate UTM tracking is the foundation of Molecule Data's attribution reporting. If this part is set up incorrectly, we will not be able to provide accurate reports. We will help you along the way with detailed instructions and live customer support, and it is important to keep using the same structure when creating new campaigns in all supported channels.

## The basics

There are many different ways to structure UTM parameters, and every marketer usually has their own beloved structure per channel. You don't need to worry about this — in these guides we explain how to keep most of your current UTM structure intact, so other tools like Google Analytics are not disturbed.

If you are not familiar with UTM parameters, you can read about them [here](https://en.wikipedia.org/wiki/UTM_parameters) or watch this [video](https://www.youtube.com/watch?v=pNRgUq5sDhc). Google also offers a handy [campaign URL builder](https://ga-dev-tools.web.app/campaign-url-builder/) that generates UTMs without mistakes.

For Molecule Data to work properly, you must copy and paste the provided template into the right field for each channel. The following pages walk you through this channel by channel:
