Lead – SEO WIKI
Lead (lead) – this is an action that the user performs with receiving further rewards from the advertiser.
There are two types of lead actions that are paid by advertisers: CPL (cost-per-lead – pay per lead) and CPA (cost-per-action – pay for lead action). In the case of CPL, payment takes place for the lead transition, that is, a manifestation of his interest in the information of the advertiser. In the second case, the specific action of the lead is paid, for example, placing an order, registering on the site, following the link and so on.
