# 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.
