URL redirects help prevent visitors from encountering non-functioning or duplicate pages by forwarding traffic from inactive to active pages. These redirects can be permanent (301) or temporary (302).

301 Redirects (Permanent)

  • Informs search engines that a page has permanently moved
  • Transfers ranking from old page to new page
  • Use when:
    • Changing page URLs
    • Deleting pages
    • Importing content with different URL structures
    • Redirecting to different domains

302 Redirects (Temporary)

  • Indicates temporary page relocation
  • Maintains original page ranking
  • Use when:
    • Temporarily removing pages for updates
    • Rotating seasonal content
    • Replacing pages temporarily

Creating Redirects:

  1. Open Developer Tools panel
  2. Click URL Mappings
  3. Add redirects using proper formatting
  4. Click Save

Format Structure:

/old-url -> /new-url 301

For Collection Pages (blogs, stores, events):

/old-collection/[name] -> /new-collection/[name] 301

Important Formatting Tips:

  • Match case sensitivity
  • Avoid ?, &, or # symbols
  • Limited to 400 KB (~2500 lines)
  • Redirects process top to bottom
  • Only works if original page is deleted/deactivated

Common Examples:

  1. Modified URLs:
/about-us -> /team 301
  1. Deleted Pages:
/history -> / 301
  1. Seasonal Content:
/summer-sale -> /fall-sale 302
  1. External Domains:
/fundraiser -> https://external-domain.com 301

Troubleshooting:

  • Verify redirect format is correct
  • Ensure destination pages are active
  • Check for redirect loops
  • Confirm proper URL structure
  • Monitor for 404 errors

Remember: Always test redirects after implementation to ensure proper functionality and user experience.
