Referrer and UTM Parameters ​

Pirsch supports special URL query parameters to improve the quality of your statistics. They can be used to reduce the number of unknown referrers on the dashboard and to track your paid or unpaid marketing campaigns.

Setting the Referrer ​

The following parameters can be added to a link to set the referrer:

  • ref
  • referer (due to a typo in the HTTP specification)
  • referrer
  • source
  • utm_source

We recommend using ref as it is the shortest, or utm_source when used with other UTM parameters. A simple example of a query parameter is https://example.com/?ref=Docs. When visitors click on the link, they will appear under Docs in the referrer panel.

Urchin Tracking Module (UTM) parameters were first introduced by Google Analytics' predecessor, Urchin, and are a widely accepted tool for tracking the effectiveness of online marketing campaigns. With Pirsch, you can use UTM parameters to break down how many people visited your website and compare the results of your campaigns.

A UTM parameter is added to a link in the same way as referrers, as described above. For example, to track how many visitors came from a paid newsletter, you can add the source, medium and campaign to the URL: https://example.com/?utm_source=Newsletter&utm_medium=Email&utm_campaign=Paid+Newsletter. How you use these parameters is up to you. To add spaces to a parameter, use %20 or a plus sign (+): ?utm_source=with+space or ?utm_source=with%20space.

utm_source, utm_medium and utm_campaign are essential parameters that you usually set for a campaign. utm_content and utm_term can be used to further break down the traffic and are often used for A/B testing. The panels for these parameters will only appear on the dashboard if you filter on one of the essential parameters.

UTM Source ​

utm_source identifies the source of the traffic. This could be a website or a newsletter, for example.

UTM Medium ​

utm_medium identifies the medium, such as social media or Twitter to be more precise.

UTM Campaign ​

utm_campaign identifies the marketing campaign, such as summer sale.

UTM Content ​

utm_content identifies which content drove the traffic. For example, if you have multiple links to the same page in a newsletter, you can tell which link was clicked. Examples of utm_content are top and bottom, or menu and sidebar.

UTM Term ​

utm_term is only relevant for paid ads and is used to filter for search terms used by visitors.
