Marketing pages are one column layouts that have an optional main navigation bar that is unique to that marketing section and do not display the mega footer. They are best used for marketing and email purposes.
You would edit a Marketing page like a Standard page in a one column layout. The main difference in a marketing page is that there is no side navigation option. Instead, you have the option to add a custom main navigation, this is the orange bar navigation that appears after the header.
*The unique marketing navigation is connected from the folder directory variables, if you are not a level 10 user please submit a project request to your lead administrator.
An administrator can also disable the page's template links (this includes the header and copyright links).
