A sales funnel is a marketing concept that illustrates the journey potential customers go through before making a purchase. It typically consists of several stages, starting with awareness, where customers first learn about a product or service, followed by interest, consideration, and finally, the decision to buy. Each stage narrows down the number of potential buyers, hence the term "funnel." Businesses use the sales funnel to identify where they can improve their marketing strategies and increase conversions. By analyzing customer behavior at each stage, companies can tailor their messaging and offers to better meet the needs of their audience, ultimately driving more sales and enhancing customer satisfaction.
