Landing pages are used to create one-off campaigns where all you need is a single page to help maximize the conversion rate for your products, features, or services. You'll find a contest landing page sample to dive into as an example of the marketing content that you can create.
The landing page manager is similar to your site manager but focuses on creating and editing the page settings of a single landing page used for marketing campaigns. Managers and administrators can create new landing pages. Editors can update existing landing pages by editing content directly on the landing preview, or by using the content editor.
