Using UTM Parameters

Requires Pro Standard or higher

UTM parameters are a subset of URL parameters used to track the performance of online marketing campaigns. Here's a quick summary:

utm_source
Tracks the source of the visitor (eg. google).
utm_medium
Tracks the channel of the clicked link (eg. search).
utm_campaign
Tracks the campaign associated with the visit (eg. black_friday).
utm_term
Tracks the search terms or keywords associated with the visit (eg. widget%20sale).
utm_content
Tracks the actual link clicked (eg. buy_now).

Carrd supports UTM parameters in two ways: automatically via form elements, and manually via variables.

Via Form Elements

To automatically include all detected UTM parameters with a form's submissions, enable its Collect UTM parameters option (if available). The values will then be processed based on the form's mode:

Custom

Via Variables

Requires Pro Plus or higher

Like other URL parameters, the values of UTM parameters can be accessed and used via variables. For example, linking to the following URL from a button will automatically pass along the values of utm_source and utm_medium:

https://vaporware.ext/?utm_source={{url.utm_source}}&utm_medium={{url.utm_medium}}
