# UTM parameters

Marketers use UTM parameters to track the effectiveness of online campaigns across traffic sources and publishing media. The parameters identify the campaign that refers traffic to a specific website and can be parsed by analytics tools and used to populate reports.

Copying these parameters and injecting them into your form submissions manually is tedious and error-prone, we built Formtrack to automate this integration.

# Installation & usage

Add the Formtrack script.

<script src="https://unpkg.com/@formspark/formtrack" async></script>

Add a data-formtrack attribute to your form element.

<form action="https://submit-form.com" data-formtrack>
  <input type="text" name="message" />
  <button type="submit">Send</button>
</form>

Formtrack will now automatically inject the supported parameters into your HTML form submissions.
