The document discusses defining a target audience for a website. It recommends first determining the website's purpose and intended users. Key questions to answer include the audience's demographics like age, gender, location and interests to develop a clear profile. The profile should then be used to guide website development to best meet the target audience's needs and encourage them to engage with the site.
