URL Mappings: How to Set Up 301 & 302 Page Redirects
URL mappings are powerful tools for managing website traffic and SEO by forwarding visitors from inactive to active pages. There are two main types of redirects:
301 Redirects (Permanent)
- Used for permanent URL changes
- Transfers search engine ranking to new page
- Best for: URL changes, deleted pages, domain changes, or imported content
- Tells search engines the move is permanent
302 Redirects (Temporary)
- Used for temporary URL changes
- Maintains original page's search ranking
- Best for: Seasonal content, temporary updates, or rotating pages
- Tells search engines the move is temporary
Creating Redirects:
- Access Developer tools panel
- Click URL mappings
- Add redirects using correct format:
old-url -> new-url 301/302
- Click Save
Key Formatting Rules:
- Match URL capitalization
- Avoid ?, &, # symbols (except RSS feeds)
- Follow proper syntax: old-url -> new-url redirect-type
- Limited to 400 KB (~2500 redirect lines)
- Higher redirects take priority
Common Use Cases:
For Single Pages:
/old-page -> /new-page 301
For Multiple Blog Posts:
/old-blog/[name] -> /new-blog/[name] 301
For Store Products:
/old-store/p/[name] -> /new-store/p/[name] 301
Important Notes:
- Can't redirect image/file URLs
- Homepage (/) can't be redirected
- Redirects only work if original page is deleted/disabled
- Only works with connected domains
- Keep redirect list manageable by removing inactive ones
Troubleshooting:
- Check correct formatting
- Ensure destination pages are active
- Verify redirect type (301/302)
- Monitor for redirect loops
- Watch for character limits
