301 redirects are essentially Legacy URL redirected pages. You can map "legacy" URLs from your existing website to your new site structure so that users do not receive error messages for bookmarked pages or search results.
1. Select Settings (gear icon) in the navbar
2. Select Legacy URLs
3. Complete the first field with the URL that users will enter in their browser
4. Complete the second field with the URL that the users will actually arrive at
5. Select Save
Redirect from: Enter a legacy URL path to redirect from. This should not contain a domain name; rather it should be everything after the domain name (e.g. /my-legacy-page.html)
Redirect to: Select content or enter a URL to redirect to (e.g. /newest-legacy-page.html)
