Pay Per Lead (PPL) affiliate marketing program pays the affiliates when they generate leads at the destination website. No sale is required for the affiliates to get paid. Lead generation usually involves capturing the contact information of the visitor directed by the affiliates. The merchant qualifies commissionable leads and affiliates get paid only after the visitors qualify as leads by completing the sign-up process. Generally, the visitor is expected to complete a sign-up form, membership registration or subscription to be validated as a lead. The non-cash conversion activity enables merchants to contact the visitor later with irresistible offers. The lead generation page could be a simple sign up form or a complicated one with multiple pages.
