Which attribution model attributes 100% of a conversion to the last Google Ads channel clicked before converting?

• A. Ads-preferred attribution model
• B. First-click attribution model
• C. Time decay attribution model
• D. Linear attribution model

Answer: (A)

Credit is given entirely to the final Google Ads interaction that occurred before the conversion. This means the last Google Ads click is the sole source of conversion credit, making that moment the decisive touchpoint in this model. In practice, this emphasizes the impact of the last ad impression on driving the sale, which is why it’s described as the ads-preferred attribution model in this context.

This approach differs from first-click attribution, which assigns all credit to the initial touchpoint; time decay, which allocates more credit to touchpoints closer to conversion but distributes some to others; and linear attribution, which splits credit evenly across all touchpoints.
