How To Create A Custom 404 Error Page in Squarespace
What you’ll need: A specific page on your site to assign
How to add it:
Navigate to your Design Menu
Select 404 page
Use the drop down menu to select the page you want to use
Click save on the top left hand side
Important info: I recommend moving this page to the not linked section of your site. You can also hide it from search results by selecting the page settings menu and opening the SEO section you can toggle on the option to hide the page from search results.
