From the Website Portal, navigate to Content > Design > Landing Pages.
Find the Landing Page you want to edit in the list and either click the Landing Page name hyperlink or the Edit icon in the actions column in the list view.
The following tabs are only displayed when an existing Landing Page is being edited:
The SEO Tab lets you view and edit the page’s SEO related information such as the Meta Title, Meta Description, Meta Keyboard, whether the page is Indexed or not, and whether to allow the page to be marked as No Follow.
The Header/Footer Tab lets you view and edit the page specific header and footer code.
When you are done editing, click Save and Close or Update if you still are working on the page and you just want to save your progress.
