GA4Lands in Paid Search when the source is a recognised search engine.
Enter a landing page URL to generate your tracked link.
Why the medium value decides your reporting.
GA4 assigns every session to a default channel by pattern matching the source and medium. Get the medium wrong and the spend still happens, it just lands in Unassigned where no one reviews it.
01 / Fixed rules
Medium is matched against fixed rules. affiliate and sms must be exact, and only display, banner, expandable, interstitial, cpm reach the Display channel.
02 / Both halves
Paid channels need both halves. A paid medium with a source GA4 does not recognise drops you into Paid Other instead of Paid Search or Paid Social.
03 / AI traffic
AI traffic has no native channel yet. referral is the cleanest mapping for ChatGPT and Perplexity clicks until GA4 adds one.
