Redirects send users and search engines from one URL to another. They are essential during site migrations, URL changes and HTTPS moves, but mistakes are common: chains of multiple redirects, loops that never resolve or temporary redirects used for permanent moves. Redirect checker tools reveal exactly what happens when a URL is requested.

When to Check Redirects
- After moving from HTTP to HTTPS
- After changing domain or permalink structure
- When merging or deleting content
- When setting up a CDN or new host
- When Search Console reports redirect errors
Bulk Checking
For large sites, use site crawlers or bulk redirect checkers to test many URLs at once. Export results and prioritise important pages and URLs with backlinks.
Best Practices
- Use 301 or 308 for permanent moves
- Keep redirects to a single hop where possible
- Update internal links to final URLs
- Remove redirected URLs from sitemaps
- Keep important redirects in place long-term
Browser Developer Tools
You can also see redirects in the Network panel of browser developer tools by loading a URL and inspecting the sequence of requests.
Common Mistakes
- Redirecting all old URLs to the homepage
- Creating new chains with each URL change
- Forgetting www and non-www variations
- Relying on JavaScript or meta refresh redirects
Frequently Asked Questions
Do redirect chains hurt SEO?
Long chains slow users and crawlers; Google may stop following very long chains. Keep them short.
How many redirects are too many?
Ideally one hop; avoid chains of more than a few.
Is 302 bad for SEO?
Not when used for genuinely temporary moves.
Can redirect checkers test mobile?
Some tools let you choose user agents.
Conclusion
Redirect checker tools show exactly how URLs resolve. Use them to confirm clean, single-step permanent redirects to the right destinations, fix chains and loops and keep migrations smooth for users and search engines.
