Final answer:
To set up a successful campaign, it's important to give view-through credit, differentiate between prospecting and retargeting, and focus on specific geographies, so all options apply.
Step-by-step explanation:
In order to set your campaign up for success, you should consider several factors that can significantly affect the outcome. This includes giving view-through credit, which acknowledges the impact of an ad viewed by the audience even if they did not immediately act upon it.
Another factor to take into account is the importance of treating prospecting and retargeting separately, as they serve different purposes and require different strategies; prospecting is about finding new potential supporters while retargeting focuses on re-engaging those who have already shown interest. Additionally, focusing on a specific geography, such as targeting urban or rural areas, can help tailor the campaign message to the unique characteristics and concerns of these demographics, potentially increasing effectiveness. Therefore, the answer to the question is D. All apply.
