What does the first-click attribution model do?

• A. Distributes attribution equally across all channels engaged with before conversion.
• B. Attributes 100% of the conversion to the last channel clicked before conversion.
• C. Attributes 100% of the conversion to the first channel clicked before conversion.
• D. Attributes to the channel with the most spend.

Answer: (C)

Attribution models determine how credit for a conversion is distributed across touchpoints in the customer journey, and the first-click model assigns all credit to the very first channel the user interacted with before converting. This means even if later channels played a role, the initial touch gets 100% of the conversion credit. This approach emphasizes which channel sparked the journey and began the customer’s path toward conversion.

The other options describe different approaches: a last-click model would hand all credit to the final channel before conversion; distributing credit equally across all touched channels would spread credit rather than concentrate it on the first interaction; and attributing based on the channel with the most spend isn’t a standard attribution method.
