Microsite
A Microsite (or minisite) serves the same purpose as a landing page, which is to deliver a very focused user experience to a very specific, targeted visitor, and to track their traffic. Whereas landing pages are single pages, Microsites are a cluster of pages and offer a more substantial user experience.
Microsites are generally independent from the main site, in both purpose, message, and design, and the microsite’s home page can have its own domain name or subdomain.
