URL redirects transfer traffic from old pages to new ones through 301 (permanent) or 302 (temporary) redirects. Here's how to effectively manage URL mapping:

301 vs 302 Redirects

301 Redirect (Permanent)

  • Transfers search engine ranking to new page
  • Use when:
    • Changing page URLs permanently
    • Removing pages
    • Importing content with different URLs
    • Redirecting to different domains

302 Redirect (Temporary)

  • Maintains original page ranking
  • Use when:
    • Temporarily updating pages
    • Rotating seasonal content
    • Switching between services

Creating Redirects

Format your redirects as:

old-url -> new-url 301/302

Key Guidelines:

  • Original URL must not exist
  • New URL must be active
  • Case-sensitive matching
  • Avoid ?, &, # symbols
  • 400 KB limit (≈2,500 redirects)
  • Higher redirects take priority

Redirecting Multiple Items

For collection pages (blogs, stores, events):

  • Use [name] variable to redirect all items
  • Example:
    /old-blog/[name] -> /new-blog/[name] 301

Common Scenarios

Page URL Change:

/about -> /team 301

Deleted Page:

/history -> / 301

External Domain:

/fundraiser -> https://external-site.com 301

Seasonal Updates:

/summer-sale -> /winter-sale 302

Troubleshooting

Common errors:

  • Missing parts (arrow or redirect type)
  • Invalid format
  • Multiple redirects within 2 minutes
  • Redirecting to invalid pages

For RSS feeds, remove query parameters:

/feed -> /new-feed 301

Remember to clean up old redirects and regularly verify redirect functionality to maintain optimal site performance.
