A standalone website or single web page. These sites are typically used to promote a company's products, services, campaigns, events, or brand. Microsites often have a different domain or subdomain from the company's main website.

In postsecondary education, microsites are increasingly being used to house information (course offerings, payment, shopping cart experience, etc.) for specific audiences such as those seeking continuing studies and professional development offerings.

Example:  In Ontario, Canada, Western University’s Continuing Studies microsite houses non-credit and credit-bearing certificates and professional education offerings. The site recognizes that a distinct web experience designed to attract and engage customers seeking continuing studies programs and courses is needed—that customers for the microsite are different than visitors the main campus website is set up to serve.
