Describe an attribution model and explain how it affects budget allocation.

• A. A rule-set to assign credit across touchpoints; e.g., last-click vs multi-touch; attribution shapes optimization and budget distribution across channels.
• B. An entity that monitors social media follower counts.
• C. This model determines the best creative asset for a campaign.
• D. It has no impact on channel budgeting.

Answer: (A)

An attribution model is a rule-set that assigns credit for a conversion across the different touchpoints a customer interacts with on their path to purchase. This matters for budget because the model determines which channels are seen as driving or supporting conversions, and those insights guide how you allocate spend. If you use a last-click approach, the final touchpoint gets most or all credit, which can lead you to overinvest in channels that close sales. A multi-touch approach spreads credit across all relevant interactions, giving visibility to upper-funnel or assistive channels that help raise awareness or nurture leads. That fuller picture helps you optimize and reallocate budgets toward the channels that truly contribute to outcomes, not just the last action.

Other options don’t fit because they describe functions unrelated to attribution (like monitoring followers or selecting a creative asset), or they claim there’s no impact on budgeting, which contradicts the purpose of attribution—how value is assigned to touchpoints to inform spending decisions.
