Redirects are essential tools in web development and SEO. They help guide users and search engines from outdated or changed URLs to relevant, live pages. But while good redirects can preserve SEO value and improve user experience, bad redirects can tank rankings, confuse crawlers, and even break your site.
In this post, we’ll cover:
- The difference between good and bad redirects
- Examples of each
- Best practices to avoid redirect loops and chains
🟢 What Is a Good Redirect?
A good redirect sends users and search engines from one URL to another in a clear, logical, and efficient way — typically using a 301
(permanent) or 302
(temporary) status code.
✅ Examples of Good Redirects
1. HTTP to HTTPS
Why it’s good: Improves security, essential for modern web standards
http://example.com → https://example.com (301)
2. Old URL to New URL (Post Migration)
Why it’s good: Preserves SEO value during site restructuring
https://example.com/old-page → https://example.com/new-page (301)
3. Non-WWW to WWW (or vice versa)
Why it’s good: Canonicalizes URLs for better SEO consistency
http://example.com → http://www.example.com (301)
4. Redirecting Deleted Content to Closest Match
Why it’s good: Prevents 404s and improves user experience
https://example.com/outdated-product → https://example.com/new-product (301)
5. Temporary Maintenance or A/B Testing
Why it’s good: Useful for short-term rerouting (use 302
or 307
)
https://example.com → https://example.com/maintenance (302)
🔴 What Is a Bad Redirect?
A bad redirect causes confusion, traps users or bots in loops, or results in SEO issues like lost rankings, duplicate content, or crawl inefficiencies.
❌ Examples of Bad Redirects
1. Redirect Loops
Page A (301) → Page B Page B (301) → Page A Result: A → B → A → B → ...
2. Circular Redirect Chain
Page A (301) → Page B Page B (301) → Page C Page C (301) → Page A Result: A → B → C → A → ...
3. Self-Redirects
Page A (301) → Page A Result: A → A → A → ...
4. Mobile/Desktop Redirect Loop
Desktop version (301) → Mobile version Mobile version (301) → Desktop version Result: Infinite redirect switching based on user agent
5. Parameter-Based Loop
Page A (301) → Page A?ref=abc Page A?ref=abc (301) → Page A Result: Looping variant URLs
6. HTTP to HTTPS Loop
HTTP (301) → HTTPS HTTPS (301) → HTTP Result: Security downgrade + loop
7. Trailing Slash Redirect Loop
Page A/ (301) → Page A Page A (301) → Page A/ Result: / → no-slash → / → ...
🚧 Why Bad Redirects Hurt SEO
- Wastes crawl budget — Bots may never reach your actual content
- Breaks user sessions — Users see endless loading or browser errors
- Hurts page rankings — Redirect chains dilute link equity (PageRank)
- Creates duplicate content — Search engines may index both versions
🛠️ Best Practices for Redirects
- ✅ Use
301
for permanent redirects - ✅ Avoid chains (A → B → C) — go direct (A → C)
- ✅ Limit the number of redirects per page (ideally 1)
- ✅ Use consistent URL structure (trailing slash, lowercase, HTTPS)
- ✅ Audit redirects regularly with tools like Screaming Frog or Ahrefs
