If you're finding that one of your landing pages is not performing the way you'd like it to, you don't have to delete it - just archive it! Here's how:
1) Go to Pages at top of your account.
2) Move your curser over the landing page you would like to archive (it will look like this:)
3) Click on the three dots on the top right and select Archive.
4) Click Archive after reading the prompt.
5) Once archived, it will disappear from your Pages.
Note - You can access any archived pages by clicking ‘See archived pages’ at the bottom of the Pages Section.
