What is Landing Page and what are its types?

A simple answer...  when a web user clicks on one of your links, the page that loads first is the landing page. Take for example the simple search prompt that opens up when you try to go to Google.com.

Social media marketing sees us using perhaps several landing pages based on who our audience is. For example, a person coming to your website from the UAE will see different content on the first page they arrive (localized content) from that which will be seen by a person from USA.
