# SMS Link Parameters


Link Parameters, also known as UTM Parameters, allow tracking of your click-through rates and enable passing personalized data to the URL.

<div class="highlight tip">No matter where your Link Parameters are added, they will be included in your message's preview and character count</div>

## Individual Link Parameters

To add parameters to a single link, add them directly in the SMS builder message content field. Ie `https://www.dyspatch.io/?utm_medium=sms&utm_source=dyspatch&order_number=45920788`

<div class="highlight note">Parameters added here will take precedence over all other link parameter settings.</div>

## Link Parameters per SMS

You can add UTM parameters and Custom Parameters to all links in an SMS message on the **Link Parameters** tab. This takes precedence over Workspace link parameters.

## Link Parameters per Workspace

To set UTM parameters for all links in an entire Workspace, or an entire Organization, Admins can include them in their <a href="https://app.dyspatch.io/admin/data/link-parameters" target="_blank">Admin dashboard Link Parameters page</a>.
