Lead generation helps businesses build a pipeline of potential customers by nurturing and engaging with prospects, and providing them with relevant information and offerings to move them through the sales funnel and convert them into paying customers.

How Much Do Lead Generation Marketing Agencies Charge?

Lead generation companies use a combination of pricing models to charge for their services. In the Pay-Per-Lead (PPL) model, the agency charges for each qualified lead generated. 

Some lead generation agencies charge an hourly rate for their services which can range from $50 to $300 or more, depending on the agency’s experience and the quality of the lead.
