"A landing page is a website page with a specific purpose -- the objective of a landing page is to convert visitors into leads. While there are many types of landing pages the intent is the same -- get more leads." (Hubspot)

In the past, when newspaper ads, mailers, magazine ads, massive billboards, and other traditional marketing mediums were the only channels to advertise. Measuring the marketing return on investment (ROI) was difficult and typically created tensions between the sales and marketing departments because each believed they should receive recognition for the increase in revenue. The marketing department would mark the date a new campaign was started and, if revenue increased, they were the hero's. Then, the sales department, which was made up of pavement pounders would claim they were the hero's because they were generating the leads and closing the deals. Neither were necessarily wrong.
