What is a landing page?

A page designed to get someone to take an one action.

For a SaaS product actions usually include signing up for a service, booking a demo, or making a purchase.

A landing page is usually the first page someone lands on after clicking a link found through a search provider. A homepage is a common landing page, as are pages specifically designed to sell a product or a service.

Landing pages should be centered around one action for a user to take.
