Online lead generation is the fastest growing segment of the online advertising industry according to the Internet Advertising Bureau.
Although it is a broadly used term, Online Lead Generation refers to the practice of turning Internet traffic into an Internet Lead (where a user submits a form requesting contact) or an Inbound Call (where a user calls the Advertiser). Three common ways in which online advertising is purchased is CPM(Cost per Thousand impressions), CPC (Cost Per Click), and CPL (Cost Per Lead).
