First-Click Attribution
All credit to the first touchpoint in the journey
In Simple Words (Zero Jargon):
All credit to the first touchpoint in the journey
Why It Is Critical
First-click attribution assigns 100% of conversion credit to the initial discovery touchpoint. While it ignores middle and closing interactions, it is a valuable lens when compared side-by-side with last-click data to see which discovery channels start journeys vs which ones finish them.
