🔄 Redirect Checker

💡 Helps detect cloaking or user-agent-specific redirects

🔄 Trace every hop in a redirect chain, classify each step (301 vs 302, HTTPS upgrade, www toggle, trailing-slash, cross-domain) and surface SEO problems — long chains, mixed types, downgrades, loops.

Redirects: Where Sites Quietly Lose Rankings

Redirects are how the web survives renames, restructures, HTTPS migrations, and consolidations. They're also where ranking signals leak away if you're not careful. A handful of common mistakes — using 302 instead of 301 for a permanent move, chains of three or more hops, downgrading from HTTPS to HTTP at any step, or accidentally creating a loop — can quietly drop a site's organic visibility for months before anyone notices.

According to Google Search Central, proper redirect implementation is essential for maintaining search visibility during site migrations. Our Redirect Checker helps you identify and fix these issues before they impact your mobile SEO and Core Web Vitals.

What This Tool Does

Our Redirect Checker follows every redirect, times each hop, classifies the type (permanent vs temporary, scheme upgrade, www toggle, slash toggle, cross-domain) and calls out the issues that hurt SEO. Toggle the user-agent comparison to detect cases where bots are sent down a different path than humans — a smell of cloaking or fragile redirect logic.

This tool is essential for maintaining a mobile-friendly website. Combined with our HTTP Status Checker, you can ensure your redirects are properly configured for both users and search engines.

301 vs 302 vs 308: Understanding Redirect Types

301 Moved Permanently

The 301 redirect is permanent and passes nearly all PageRank to the new URL. According to Google's documentation, 301 redirects preserve the vast majority of ranking signals. For an HTTPS migration, a www toggle, or a permanent move always use 301.

302 Found / 307 Temporary Redirect

The 302 redirect is temporary and Google is more conservative about transferring signals through it. Only use 302 when the move is genuinely temporary. Our Redirect Checker identifies when 302s should be 301s.

308 Permanent Redirect

The 308 redirect is permanent and preserves the request method (POST stays POST). Use 308 when method preservation matters. It's less common but increasingly supported.

Why Redirect Chains Matter for SEO

1. Page Speed and Core Web Vitals

Each extra hop in a redirect chain adds latency for users. This directly impacts Core Web Vitals, particularly Largest Contentful Paint (LCP). web.dev recommends minimizing redirects for optimal performance. Use our Page Speed Checker to measure the impact.

2. Link Equity and PageRank

Industry research suggests roughly 5–10% of equity dissipates per extra hop. Updating incoming links to point to the final URL is one of the highest-leverage technical SEO tasks you can do after a migration.

3. Crawl Budget

Redirect chains waste crawl budget. Googlebot spends time following redirects instead of indexing new content. Google Search Central recommends keeping redirects direct.

4. Mobile-First Indexing

With mobile-first indexing, Google primarily crawls and indexes the mobile version of your site. If mobile URLs have different redirect chains than desktop, your mobile SEO can suffer. Our Redirect Checker helps identify these discrepancies.

Common Redirect Issues and How to Fix Them

1. Using 302 Instead of 301

The Problem: Temporary redirects used for permanent moves, diluting link equity.

The Fix: Change 302s to 301s for permanent redirects. Use our Redirect Checker to identify these issues.

2. Long Redirect Chains

The Problem: Multiple redirects (e.g., A → B → C → D) slow down page loads.

The Fix: Update redirects to point directly to the final destination. Our tool shows you every hop in the chain.

3. HTTPS to HTTP Downgrades

The Problem: Redirecting from secure HTTPS to insecure HTTP at any point.

The Fix: Ensure all redirects maintain HTTPS. Use our SSL Checker to verify your HTTPS configuration.

4. Mixed www/non-www Redirects

The Problem: Inconsistent handling of www vs non-www versions.

The Fix: Choose a preferred domain and redirect the other version consistently. Use our Canonical URL Checker to verify.

5. Redirect Loops

The Problem: A → B → A creates an infinite loop.

The Fix: Review your redirect configuration and break the loop. Our tool detects and reports loops.

Best Practices for Redirect Implementation

1. Use 301 for Permanent Moves

For any permanent URL change, use 301 redirects. They preserve SEO value and signal to search engines that the move is permanent. Google recommends 301 for permanent moves.

2. Minimize Redirect Chains

Keep redirect chains to a maximum of 3 hops, and ideally zero. Each redirect adds latency and can dilute link equity. Our Redirect Checker helps you identify and fix chains.

3. Maintain HTTPS Throughout

Always redirect to HTTPS, never away from it. This ensures security and maintains user trust. Use our SSL Checker to verify your certificates.

4. Update Internal Links

After implementing redirects, update internal links to point directly to the final URL. This reduces redirect chains and improves site performance. Use our Link Checker to identify internal links that need updating.

5. Set Correct Canonical URLs

Even with proper redirects, set canonical URLs to indicate the preferred version. Our Canonical URL Checker helps verify your implementation.

User-Agent Specific Redirects: Hidden SEO Risks

Some websites serve different redirects based on the user-agent. This can be a sign of cloaking, which violates Google's Webmaster Guidelines. Our Redirect Checker includes a user-agent comparison feature that checks:

  • Googlebot: How Google's crawler sees your redirects
  • Mobile Safari: How mobile users experience your redirects

If these differ significantly, you may have a problem that needs investigation.

Frequently Asked Questions (FAQs)

What is a Redirect Checker?

A Redirect Checker is a tool that traces the full redirect chain of a URL, showing every hop, timing, and status code. It identifies SEO issues like long chains, mixed types, and loops that can impact search rankings.

How do redirects affect SEO?

Redirects directly impact mobile SEO by affecting crawlability, link equity, and user experience. Proper 301 redirects preserve rankings, while 302s, chains, and loops can harm visibility. Google's guidelines emphasize proper redirect implementation.

What's the difference between 301 and 302 redirects?

301 redirects are permanent and pass full link equity. 302 redirects are temporary and don't pass full ranking signals. Use 301 for permanent moves and 302 for temporary ones. Our Redirect Checker identifies which type you're using.

Are redirect chains bad for SEO?

Yes, redirect chains can slow down page loads, dilute link equity, and waste crawl budget. Keep redirects direct and chains minimal. Our tool shows you every hop in the chain.

How many redirects are acceptable?

For optimal performance, keep redirect chains to 3 hops or fewer. Each redirect adds latency, especially on mobile networks. web.dev recommends minimizing redirects for better Core Web Vitals.

What is a redirect loop?

A redirect loop occurs when URL A redirects to B, and B redirects back to A, creating an infinite cycle. This prevents users and search engines from accessing your content. Our tool detects and reports redirect loops.

Should I use 301 or 308 redirects?

Both are permanent redirects. The difference is that 308 preserves the HTTP method (POST stays POST), while 301 may change POST to GET. For most SEO purposes, 301 is sufficient and more widely supported.

Why should I care about user-agent specific redirects?

User-agent specific redirects can indicate cloaking, which violates Google's Webmaster Guidelines. Our user-agent comparison feature helps you detect if bots and users see different redirects.
