What is a key impact of not competing for last-touch credit in a marketing plan?

The correct response focuses on a significant aspect of marketing attribution and its effects. Not competing for last-touch credit can indeed lead to situations where ads do not reach their intended audience effectively. This is because prioritizing last-touch credit often means that marketers focus heavily on the final interaction before a conversion, potentially overshadowing other important touchpoints in the customer journey.

When marketers neglect these earlier interactions, it may result in a failure to understand the complete customer experience. Therefore, advertising efforts might miss out on engaging customers through channels where they had previously expressed interest or interacted with the brand. This lack of comprehensive view can diminish the overall effectiveness of a marketing plan since it overlooks the synergy between various marketing channels that work collectively to drive conversions.

The other options, while they may have relevance in different contexts, do not directly reflect the specific implication of not competing for last-touch credit as clearly as the possibility that ads may not reach the audience effectively.
