Redirect chain: Definition and Use Cases

By Anatoly Oshmanovsky · Updated Apr 17, 2026

TL;DR:

Redirect chain is a sequence of 301/302 redirects for a single URL. Example: http://example.com → https://example.com → https://www.example.com → https://www.example.com/. Long chains (> 2 hops) slow loading and consume Google crawl-budget.

What is Redirect chain

Redirect ChainsEach extra redirect adds 100-300ms latency and reduces PageRank along the chain.

HTTP to HTTPSVerify the redirect is performed correctly without intermediate unencrypted hops.

Redirect LoopsCircular redirects cause ERR_TOO_MANY_REDIRECTS error and complete page unavailability.

301 vs 302 Codes301 permanently passes PageRank, 302 is a temporary redirect without passing SEO weight.

Redirect checker: optimize redirect chains

Incorrect or long redirect chains slow down the site, lose PageRank and confuse search crawlers. The tool visualizes the full redirect chain with response codes and timing for each hop.

Full hop chain

Shows each redirect step: URL → code → URL → code, through to the final destination.

Time per hop

Measures latency at each redirect step for precise identification of performance bottlenecks.

Redirect type

Distinguishes 301, 302, 303, 307, 308 — each has different behavior for SEO and browsers.

Loop detection

Automatically detects circular redirects and warns before the browser throws an error.

Common Mistakes

❌

Chains of 3+ redirectsHTTP → HTTPS → non-www → www — that's three redirects instead of one. Merge them into a single direct redirect.

❌

Using 302 instead of 301302 for permanently moved pages means losing PageRank. Use 301 for final migrations.

❌

Redirecting HTTP to HTTP before HTTPSAn intermediate unencrypted hop creates an MITM vulnerability and adds an extra request.

❌

Not updating internal linksRedirects are not a substitute for updated links. Links to original URLs should be updated directly.

Best Practices

✓

Use one redirect: HTTP+www → HTTPS+non-wwwConfigure a single nginx/Apache rule combining both conditions into one 301 redirect.

✓

Check redirects after migrationsDomain change, HTTPS migration, URL structure redesign — all create new redirect chains.

✓

Remove stale redirectsRedirects accumulated over years create hidden chains. Audit .htaccess and configs quarterly.

✓

Control redirects in sitemapSitemap should only contain final URLs without redirects — otherwise crawlers waste crawl budget.
