Many of our users ask if they can unpublish a page without taking the whole website offline. Currently the answer is no, but there are some steps you can take that will essentially make your page "unpublished". You can either:
Make sure no other pages on your site link to this page. If there are no links going to a page, it will be hard for a visitor to your site to stumble across your site
In the page settings panel for your page, go to SEO settings, uncheck 'Index Page' and 'Follow Page', and click the Save Changes button at the bottom. This will help prevent the page from showing up in search results, in case your site is live with a custom domain.
Unpublishing a specific page is a feature we're currently working on, so stay tuned for that release!
