Source and Medium dimension values

The Source and Medium dimensions indicate where website visitors come from. Here is how they are determined:
  • URL parameters — when someone lands on your site, SegmentStream first looks for utm_source and utm_medium parameters in the URL. If these exist, their values are used for Source and Medium. If they are absent, SegmentStream uses the advertising platform name (such as Google Ads or Facebook Ads) as the Source and cpc as the Medium.
  • Google traffic — if the link contains parameters like gclid, wbraid, or gbraid, indicating traffic from Google, the Source is set to google and the Medium to cpc.
  • Organic search — when visitors come from a search engine’s unpaid results, the search engine domain is recorded as Source (for example, google.com) and the Medium is set to organic.
  • Referral traffic — if visitors come from another website, that domain is used as Source and the Medium is set to referral.
  • Direct visits — if visitors type your URL directly into their browser, or the source cannot be identified, Source is set to (direct) and Medium to (none).
