Abstract: Techniques for measuring the value of marketing contributions to deals are discussed. An account interest score of an account for a product or service is generated at a time of sale of the product or service to the account. The generating may be based on the individual interest scores of the members of the account for the product or service. The individual interest scores may be calculated based on marketing output that pertains to the product or service and is received by the members of the account before the sale. A determination is made that the account interest score exceeds a marketing contribution threshold value. Based on the determination that the account interest score exceeds the marketing contribution threshold value, a credit for the sale is assigned to a marketing organization that created the marketing output received by the members of the account before the sale.
