Cost Per Lead
The Cost per Lead metric measures how cost-effective your marketing campaigns are when it comes to generating new leads for your sales team. This metric is closely related to other key business metrics such as the cost to acquire new customers. The purpose of this metric is to provide your marketing team with a tangible dollar figure so they understand how much money is appropriate to spend on acquiring new leads.
The cost per lead metric also provides important data to use in your return on investment calculations. In fact, each stage of the purchase funnel should have similar metrics associated with it, such as cost per visitor and cost per win. Likewise, these metrics can be used to monitor individual campaigns such as AdWords, banner ads, or social ads, or the sum of your marketing efforts.
