Lead scoring is a way of ranking and prioritizing leads, or potential customers, based on their value and interest in your products or services. Lead scoring uses both explicit and implicit data, such as professional information, website engagement, and buying cycle stage, to assign points or labels to each lead. Lead scoring helps align and collaborate between sales and marketing teams, and determine the right follow-up and approach for each lead. Lead scoring requires a common definition of a qualified lead between sales and marketing departments.
