An ad campaign is a coordinated series of promotional messages designed to reach a specific audience. These campaigns often use various media channels, such as television, radio, social media, and print, to convey a consistent message about a product or service. The goal is to increase brand awareness, generate leads, or drive sales. Successful ad campaigns typically involve research to understand the target audience and creative strategies to engage them. Marketers analyze the effectiveness of their campaigns through metrics like reach, engagement, and conversion rates, allowing them to adjust their strategies for better results.
