First-Click vs Last-Click Attribution

Attribution models determine how credit for a conversion is assigned across marketing touchpoints. First-click attribution gives all credit to the initial touchpoint that introduced a customer, while last-click gives all credit to the final touchpoint before conversion. Both are single-touch models with inherent limitations, but understanding their differences is critical for budget allocation decisions.

Our recommendation

Where DPL would point you.

Neither first-click nor last-click attribution tells the full story. Move to a multi-touch attribution model that distributes credit across the customer journey. If forced to pick between the two, use last-click for short sales cycles and first-click for longer consideration periods, but recognize that both are oversimplifications. Digital Point implements data-driven models that reflect how customers actually convert.
