The term "addressable" or "identifiable" refers to the ability to specifically target and reach a particular group or individual. In marketing, this means that businesses can identify and engage with consumers based on their preferences, behaviors, or demographics. This targeted approach allows for more effective communication and personalized experiences. In the context of digital advertising, addressable audiences are created using data collected from various sources, such as social media, web browsing, and purchase history. This data enables advertisers to deliver tailored messages to specific users, increasing the likelihood of engagement and conversion.
