Retargeting by scoring is a marketing strategy that involves using a scoring system to identify and target potential customers who have shown interest in a product or service. This method utilizes data analysis and algorithms to assign a score to each potential customer based on their behavior, such as website visits, clicks, and purchases. The higher the score, the more likely the customer is to convert, allowing businesses to focus their advertising efforts on the most promising leads. This approach not only increases the effectiveness of retargeting campaigns but also helps businesses save time and resources by targeting only the most relevant and engaged audience.
