Which of the following business questions can be answered with an overlap analysis?
- What was the average impressions per day per campaign per unique user_id value?
- What are the top performing geographic regions for your campaign based on purchase rates?
- What is the impact of your Sponsored Products campaigns and Amazon DSP campaigns in isolation or in combination?
Explanation: The correct answer is **What is the impact of your Sponsored Products campaigns and Amazon DSP campaigns in isolation or in combination?** because an overlap analysis helps you understand the relationship between different groups or segments by comparing how users exposed to multiple campaigns, such as Sponsored Products and Amazon DSP, overlap. This analysis enables you to determine whether the campaigns are having a combined effect or whether they perform better in isolation. It can also show the incremental impact of each campaign or their intersection on driving conversions or other metrics. The other options, such as analyzing impressions per day per unique user or identifying top-performing geographic regions based on purchase rates, are more related to other types of analysis, such as performance reporting or geographic segmentation, and are not the focus of overlap analysis.
