Some affiliate programs support the sending of lead data to you.
For the purpose of consistency, LinkClicky defines a lead as a visitor who signs up for said service but hasn’t paid for the service. They are, in effect, a lead to the merchant.
Some systems define a lead differently. LinkClicky tries to make them consistent across platforms. Some systems have a specific lead event action, while others merge them with conversion events as well.
LinkClicky separates leads into its own event named, oddly enough, Lead Event.
More specifically, for LinkClicky, a lead event has zero commission but may yield a commission in the future. It’s the next step in a sales funnel and shows higher intent by the visitor.
This data can be sent to the ad networks and retarget that visitor.
