Audience research involves gathering information about audience segments to understand their attitudes, interests, and behaviors regarding a topic. It is important to conduct audience research before finalizing a project to understand the target audience and design something that will appeal to them. There are many ways to categorize audiences, such as by demographics like age, gender, income level, and occupation. Gathering this information through surveys, interviews, and focus groups can provide insights into what the audience wants. Internet forums, social media, and online ratings are also effective research methods because many younger audiences spend time online.
