An advertiser notices that conversion data in Campaign Manager 360 is lower than expected for their Search-to-Display journeys. Which technical feature should be used to append a unique ID to the landing page URL, allowing the system to accurately attribute these click-through activities?

Enhanced attribution improves click-based attribution by appending a DCLID value to the landing page URL after eligible clicks. The Google tag can read that identifier on the landing page and associate later conversion activity with the originating click. This helps Campaign Manager 360 identify click-through activity across Google Marketing Platform display and video inventory. It is the correct technical feature when conversion data is undercounted because click identifiers are not being captured.
