What does having only one person on a marketing plan affect in terms of ads served?

When there is only one person associated with a marketing plan, it typically prevents higher ad frequency for that individual. This means that the same ad is less likely to be shown repeatedly to that specific person. In programmatic advertising, frequency capping is often implemented to avoid overwhelming users with the same advertisement, which can lead to ad fatigue. By limiting how often an individual sees the same ad, marketers strive to maintain engagement and reduce the likelihood of users becoming disinterested or annoyed with repetitive messaging.

This saturation avoidance is crucial for maintaining a positive user experience and ensuring that the ad remains impactful. In scenarios where multiple personas or segments are included in a marketing strategy, the potential for higher frequency could lead to diminishing returns on the effectiveness of the ad campaign. Thus, having only one person limits the exposure to the ad, allowing for more varied advertising approaches rather than saturating a single user's experience.

The other choices are less relevant because they speak to broader implications of ad strategies rather than directly addressing the effect of having a solitary participant in the marketing plan. For instance, ad effectiveness, competing ads, and attribution credits are influenced by various factors beyond just having one individual involved.
