Cover image for Redirect Chains Hurt SEO: Dead Link Checker Guide

You just migrated your site to a new CMS. Everything looks perfect. Then you notice page load times creeping up. Users start bouncing. Google Search Console shows declining rankings.

The culprit? Redirect chains—invisible performance killers where one redirect triggers another, then another. Each hop adds 100-400ms of latency your users feel but can't see. Meanwhile, search engines are bleeding away your SEO authority with every bounce.

A single 301 redirect is harmless. But when oldsite.com/page redirects to newsite.com/page, which redirects to www.newsite.com/page, which redirects to newsite.com/blog/page—you've just wasted half a second and 27% of your link equity. Your Core Web Vitals tank. Your conversions drop.

Broken link checkers and link monitoring tools can detect when links start redirecting, alerting you before chains accumulate. This guide shows you how redirect chains form, exactly how much they cost in performance and SEO, and the step-by-step process to check for broken links in redirect chains and eliminate them before they damage your rankings.

A redirect chain occurs when a URL redirects to another URL, which redirects to yet another URL, forming a multi-hop path before reaching the final destination. Broken link checkers detect these chains by following redirects and measuring response times.

A → B → C → D (final destination)

Here's what this looks like in practice when you request oldsite.com/product:

$ curl -IL oldsite.com/product
 
HTTP/1.1 301 Moved Permanently
Location: newsite.com/product
 
HTTP/1.1 301 Moved Permanently
Location: www.newsite.com/product
 
HTTP/1.1 301 Moved Permanently
Location: www.newsite.com/products/item
 
HTTP/1.1 200 OK

Four server round-trips just to load one page.

PatternHopsWhat Happens
Single redirect1A → B (200 OK)
Redirect chain2+A → B → C → D (200 OK)
Redirect loopA → B → A (never resolves)

Why they happen: Redirect chains typically form during site migrations, CMS changes, or when multiple URL consolidation rules stack on top of each other. A developer adds HTTP→HTTPS redirects, then another adds www consolidation, then a third changes the URL structure—suddenly you have a 3-hop chain nobody intended.

How Redirect Chains Hurt Page Speed

Every redirect hop adds round-trip latency between the browser and server. This delay is invisible in browser DevTools but devastating to user experience.

Latency per hop:

  • Desktop (broadband): 100-150ms per hop
  • Mobile (4G): 150-250ms per hop
  • Mobile (3G): 200-400ms per hop
Connection Type1 Hop2 Hops3 Hops4 Hops
Desktop100ms200ms300ms400ms
Mobile 4G200ms400ms600ms800ms
Mobile 3G300ms600ms900ms1200ms

Impact on Core Web Vitals:

Redirect chains delay the Largest Contentful Paint (LCP) metric—one of Google's primary ranking signals. Your browser can't start downloading the actual page content until it resolves all redirects.

Example: Your product page has great LCP (1.8s) when accessed directly. But 60% of traffic hits an old URL with a 3-hop redirect chain. Now their LCP is 2.3s (mobile 4G) or 2.7s (3G)—pushing you into the "needs improvement" range.

Real-world case: An e-commerce site migrated from Shopify to WooCommerce, then added Cloudflare CDN. Old product URLs went through this chain:

shopify-store.com/products/widget
  → woocommerce-store.com/products/widget (150ms)
  → cdn.woocommerce-store.com/products/widget (120ms)
  → cdn.woocommerce-store.com/shop/widget (180ms)
Total delay: 450ms before page load even starts

Mobile users on 3G saw page loads exceed 4 seconds. Bounce rate jumped 18%.

The SEO Cost of Redirect Chains

Search engines pass link equity (ranking authority) through 301 redirects, but not perfectly. Each hop in a chain leaks authority.

Link equity math (widely accepted estimates):

  • Single 301 redirect: Passes 90-95% of authority
  • 2-hop chain: 81% authority preserved (90% × 90%)
  • 3-hop chain: 73% authority preserved (90% × 90% × 90%)
  • 4-hop chain: 66% authority preserved
Redirect HopsAuthority PreservedAuthority Lost
0 (direct link)100%0%
1 hop90-95%5-10%
2 hops81%19%
3 hops73%27%
4 hops66%34%
Diagram showing SEO link equity decreasing through redirect chain from 100% to 73%

Example: Your affiliate blog has 500 backlinks pointing to an old product review URL. That URL has a 3-hop redirect chain to the new location. You're effectively wasting 135 backlinks worth of authority (27% of 500).

Crawl budget impact:

Search engines allocate a limited "crawl budget" for your site—a maximum number of pages they'll crawl per day. Redirect chains waste this budget on multiple requests for the same content.

If Googlebot has a daily budget of 10,000 URLs but encounters 4,000 redirect chains averaging 2.5 hops, it burns 10,000 requests just on redirects—leaving zero for new or updated content.

Case study: Affiliate site consolidation

An affiliate marketer consolidated three niche sites into one domain. Poor redirect planning created chains like:

site-a.com/review → main-site.com/review (temp redirect from DNS)
  → main-site.com/reviews/product (URL structure change)
  → www.main-site.com/reviews/product (www consolidation)

Results over 6 months:

  • Organic traffic: -23% (expected +15% from consolidation)
  • Average position: dropped 4.2 spots
  • Lost an estimated $8,400/month in affiliate revenue

Fixing the chains and implementing direct redirects recovered most traffic within 3 months.

Why Redirect Chains Form

Redirect chains rarely happen intentionally. They accumulate over time as different systems layer redirects on top of each other.

1. Multiple Migrations

Scenario: You migrate from WordPress to Shopify, then later to a custom platform.

old-wordpress.com/blog/post
  → shopify-store.com/blogs/news/post (migration 1)
  → custom-platform.com/blog/post (migration 2)

Each migration adds a redirect layer. The first migration's redirects stay in place, creating chains.

Scenario: You use a link shortener for social media, then add analytics tracking.

bit.ly/promo
  → yoursite.com/promo (shortener redirect)
  → yoursite.com/promo?utm_source=twitter (analytics redirect)
  → www.yoursite.com/promo?utm_source=twitter (www redirect)

Three hops to track one click.

3. Protocol + Subdomain Consolidation

Scenario: Site-wide HTTPS migration followed by www standardization.

http://site.com/page
  → https://site.com/page (HTTPS redirect)
  → https://www.site.com/page (www redirect)

Common pattern, but 2x slower than a single redirect to the canonical URL.

4. CDN Migrations

Scenario: Moving from one CDN provider to another without updating redirect rules.

cdn-old.com/assets/image.jpg
  → cdn-new.com/assets/image.jpg (CDN migration)
  → www.yoursite.com/assets/image.jpg (CDN deprecation)

5. CMS URL Structure Changes

Scenario: Changing permalink structure in WordPress or another CMS.

/2024/01/15/post-title (date-based URLs)
  → /blog/post-title (category-based URLs)
  → /content/post-title (another restructure)

Each URL structure change adds a redirect, but previous redirects aren't updated to point directly to the final destination.

Redirect chains hide in plain sight. Users experience slow page loads but don't know why. Dead link checkers and monitoring tools help expose them by tracking status changes and response times. Here's how to check for broken links and redirect chains.

Manual Detection: Browser DevTools

Step 1: Open Chrome DevTools (F12) → Network tab

Step 2: Check "Preserve log" to see all requests

Step 3: Navigate to the URL you want to test

Step 4: Look for multiple 301/302 status codes in sequence

Example output:

oldsite.com/page         301  150ms
newsite.com/page         301  180ms
www.newsite.com/page     301  120ms
www.newsite.com/blog/page 200  350ms
Total: 800ms before content loads

Manual Detection: curl Command

Command:

curl -IL https://oldsite.com/page

Flags:

  • -I: Fetch headers only (faster than full page)
  • -L: Follow redirects
  • Output shows every hop with status code and timing

Example output:

HTTP/1.1 301 Moved Permanently
Location: https://newsite.com/page
 
HTTP/1.1 301 Moved Permanently
Location: https://www.newsite.com/page
 
HTTP/1.1 200 OK

Count the 301 lines before 200 OK—that's your chain length.

Broken link checkers and link monitoring services like DeadLinkRadar detect when links start redirecting and alert you to investigate.

What gets monitored:

  • Status code changes: 200 OK301 Moved Permanently
  • Response time spikes: Sudden +300ms increase signals potential chain
  • Link health degradation: Working link becomes slow redirect

Limitation: Most dead link checkers (including DeadLinkRadar) detect that a redirect exists and measure response time, but don't automatically count hops or show the full chain. When you receive a "link started redirecting" alert, use curl or DevTools to diagnose the chain manually.

Why this matters: Redirect chains often form gradually. A link works fine for months, then a migration adds a hop. Without a broken link checker monitoring continuously, you won't notice until users complain about slow pages.

Fixing Redirect Chains

Once you've identified redirect chains, consolidating them requires careful planning to avoid breaking links or creating new issues.

Step 1: Audit All Redirects

For nginx:

grep -r "return 301" /etc/nginx/sites-enabled/
grep -r "rewrite.*permanent" /etc/nginx/sites-enabled/

For Apache (.htaccess):

grep -r "Redirect 301" /var/www/
grep -r "RedirectPermanent" /var/www/

Export to spreadsheet:

Source URLDestination URLStatusHops
oldsite.com/pagenewsite.com/page3011
newsite.com/pagewww.newsite.com/page3012

Step 2: Map Chain Endpoints

For each redirect, trace the final destination by following all hops with curl:

curl -IL oldsite.com/page | grep -E "HTTP|Location"

Identify the terminal URL (the one returning 200 OK).

Step 3: Consolidate Redirects

Before (2-hop chain):

# /etc/nginx/sites-enabled/default
server {
  # First redirect
  rewrite ^/old-page$ /new-page permanent;
 
  # Second redirect (somewhere else in config)
  rewrite ^/new-page$ /final-page permanent;
}

After (direct redirect):

server {
  # Consolidated: old URL → final destination directly
  rewrite ^/old-page$ /final-page permanent;
  rewrite ^/new-page$ /final-page permanent;
}

Before (Apache .htaccess):

Redirect 301 /old-page /new-page
Redirect 301 /new-page /final-page

After:

Redirect 301 /old-page /final-page
Redirect 301 /new-page /final-page

Search your codebase for references to old URLs:

grep -r "oldsite.com/page" /var/www/html/

Update links to point directly to the canonical URL. This eliminates redirects entirely for internal navigation.

Step 5: Test with Timing

After deploying changes, verify redirects are direct:

time curl -IL https://oldsite.com/page

Expected output:

HTTP/1.1 301 Moved Permanently
Location: https://newsite.com/final-page
 
HTTP/1.1 200 OK
 
real  0m0.18s  ← Single hop latency

Compare to pre-fix timing (should be 2-3x faster).

Set up alerts for status code changes and response time spikes on your most important URLs. Redirect chains can reappear during future migrations or configuration changes. A broken link checker provides continuous monitoring to catch new chains as they form.

Common mistake: Updating redirects in one config file but missing duplicates in another (e.g., nginx server blocks + .htaccess fallback). Always grep the entire web root.

Preventing Redirect Chains

The best redirect chain is one that never forms. Build prevention into your workflow:

1. Pre-Migration Redirect Planning

Before migrating URLs:

  • Map old URLs to new URLs in a spreadsheet
  • Identify existing redirects that will be affected
  • Plan to update those redirects to point directly to new URLs
  • Test redirects in staging with curl before deploying

Example checklist:

  • Exported current redirect rules
  • Mapped all URL changes (old → new)
  • Updated redirect rules to skip intermediate hops
  • Tested 20 sample URLs with curl timing
  • Verified no chains in staging environment

2. Redirect Governance Policy

Establish a rule: Never create redirects to URLs that themselves redirect.

Enforcement:

  • Document all redirect additions in a changelog
  • Require curl test showing single-hop redirect in PR reviews
  • Automate redirect chain detection in CI/CD pipeline

Example automation (GitHub Actions):

- name: Check for redirect chains
  run: |
    ./scripts/check-redirects.sh
    # Fails CI if any redirect chain detected

3. Quarterly Redirect Audits

Schedule recurring audits to catch accumulated chains:

Audit script (bash):

#!/bin/bash
# check-redirects.sh
 
URLS="urls-to-check.txt"
 
while read url; do
  hops=$(curl -ILs "$url" | grep -c "HTTP/1.1 30")
  if [ "$hops" -gt 1 ]; then
    echo "⚠️  CHAIN: $url ($hops hops)"
  fi
done < "$URLS"

Run quarterly:

bash check-redirects.sh > redirect-audit-$(date +%Y-%m-%d).txt

If using link shorteners (bit.ly, short.io), configure them to redirect directly to canonical URLs—not to intermediate tracking pages.

Bad:

bit.ly/promo → yoursite.com/promo → www.yoursite.com/promo

Good:

bit.ly/promo → www.yoursite.com/promo (direct)

5. Test Migrations in Staging

Before deploying URL structure changes:

  • Run full site crawl in staging with Screaming Frog
  • Filter for redirect chains (Status Code = 301, count chains)
  • Fix all chains before production deploy

6. Document Redirect History

Maintain a changelog of redirect changes with rationale:

## 2026-02-05: CDN Migration
- Moved static assets from cdn-old.com to cdn-new.com
- Updated 47 redirects to point directly to new CDN
- Verified no chains with curl audit
 
## 2026-01-12: HTTPS Migration
- Implemented HTTPS redirects site-wide
- Consolidated with existing www redirects (prevented chains)

This helps future maintainers understand the redirect landscape and avoid creating conflicts.


Prevention is easier than fixing. A broken link checker provides the foundation by alerting you when redirects appear, allowing immediate investigation. Check for broken links automatically to catch redirect chains early. Start monitoring free


Real Example: Before/After

Company: E-commerce site selling outdoor gear (127 product URLs)

Problem: Site migrated from Magento to Shopify, then restructured category URLs. Product pages had 3-hop redirect chains:

magento-store.com/catalog/product/widget-123
  → shopify-store.com/products/widget-123 (migration)
  → shopify-store.com/collections/widgets/products/widget-123 (restructure)
  → www.shopify-store.com/collections/widgets/products/widget-123 (www)

Before fix:

  • Average hops per product: 2.3
  • Average redirect latency: 340ms (desktop), 680ms (mobile 4G)
  • LCP (Largest Contentful Paint): 2.8s on mobile
  • Crawl budget wasted: 38% of Googlebot requests on redirects

Fix applied:

  1. Identified all 127 product URLs with chains
  2. Updated Magento redirects to point directly to final Shopify URLs
  3. Removed intermediate redirects from Shopify config
  4. Updated internal links to canonical URLs

After fix:

  • Average hops: 1.0 (direct redirects only)
  • Average redirect latency: 120ms (desktop), 180ms (mobile 4G)
  • LCP improvement: 2.8s → 2.4s (14% faster)
  • Organic traffic: +12% over 2 months
  • Crawl efficiency: Googlebot now crawls 41% more unique pages per day

Conversion impact:

  • Faster page loads → lower bounce rate (58% → 53%)
  • Better UX → higher conversion rate (+0.2 percentage points)
  • Revenue impact: +$1,840/month from organic traffic alone

curl timing comparison:

Before:

$ time curl -IL magento-store.com/catalog/product/widget-123
real  0m0.58s  # 580ms total

After:

$ time curl -IL magento-store.com/catalog/product/widget-123
real  0m0.18s  # 180ms total (68% faster)

The fix took 6 hours of developer time. ROI: $1,840/month = $22,080/year from a one-time investment.

Redirect chains accumulate quietly. A CMS plugin adds a redirect here, a CDN migration adds one there, a URL structure change adds another—suddenly you're bleeding 500ms of latency and 27% of your SEO authority on every page load.

The warning signs:

  • Declining Core Web Vitals scores
  • Slow page loads on URLs that used to be fast
  • Organic traffic drops after migrations
  • High bounce rates on specific pages

What to monitor with your dead link checker:

  • Product pages (especially after migrations)
  • Blog posts (URL structure changes)
  • Documentation (consolidations)
  • Affiliate links (tracking layers)

A broken link checker gives you the early warning system: status change alerts flag when links start redirecting, and response time tracking catches latency spikes before they hurt conversions. Check for broken links continuously to prevent chains before they damage your SEO.
