Short answer

Audience segmentation is the practice of dividing customers or prospects into groups based on shared attributes or behaviors, such as demographics, location, purchase history, interests, or engagement. Each segment can then receive messaging, offers, and channels suited to it. Segmentation makes marketing more relevant, improves conversion rates, and reduces wasted spend on poorly matched audiences.
