Call retargeting is a marketing strategy that involves tracking and reconnecting with potential customers who have previously interacted with a business through a phone call. This technique uses data from call tracking software to identify and target individuals who have shown interest in a product or service by calling the company. By retargeting these individuals with personalized ads or offers, businesses can increase the chances of converting them into paying customers. Call retargeting is a powerful tool for businesses looking to optimize their marketing efforts and drive more conversions from phone calls.
