A landing page can be the designated page you’re taken to when you click on an ad. It can be the page that follows a call-to-action button. A landing page can also serve as the homepage of a website. What distinguishes a webpage as a landing page is its objective — the purpose of a landing page is to convert visitors into leads.
That’s it. The differentiating component of a landing page is that it contains a lead form that asks visitors for their contact information, typically in exchange for something the visitor values.
