Li is an advertiser at a pharmaceutical company selling cold and flu medicine. She wants to compare product views across various geographical locations. Which audience type should Li use?

The correct answer is Demographic because using demographic audience data allows Li to analyze product views based on specific geographical locations, as well as other measurable characteristics such as age, gender, and income level. This audience type enables advertisers to segment their analysis effectively and understand how different groups in various regions interact with their products. In contrast, in-market audiences focus on consumers actively looking to purchase, while lifestyle audiences consider broader interests and behaviors, making demographic data the most appropriate choice for Li's comparison of product views across locations.
