What is the difference between 301 and 302 redirects?

A 301 redirect is permanent, telling search engines to transfer all SEO value to the new URL. A 302 redirect is temporary, meaning the original URL retains its search rankings. Use 301 for permanent moves and 302 for temporary changes like A/B testing.

Why are redirect chains bad for SEO?

Redirect chains (A redirects to B, B redirects to C) slow down page load, dilute link equity with each hop, and may cause crawlers to give up after too many redirects. Google recommends keeping chains to 3 hops or fewer.

Why does this tool show CORS limitations?

Browsers enforce CORS security policies that prevent JavaScript from following redirects across different origins. This tool detects whether a redirect occurs but cannot read the Location header from cross-origin responses. For full redirect chain analysis, use server-side tools like curl.

⚠️ Browser Limitation: Due to CORS security policies, browsers cannot follow cross-origin redirect chains. This tool detects whether a redirect occurs and shows the final destination. For complete redirect chain analysis with status codes, use curl -vL from the command line.

HTTP Redirect Types Guide

301

Moved Permanently

The URL has permanently moved. Search engines transfer full SEO value. Best for: domain migrations, permanent URL changes, HTTP to HTTPS.

302

Found (Temporary)

Temporary redirect. Original URL keeps its rankings. Best for: A/B testing, maintenance pages, geo-targeting, seasonal content.

307

Temporary Redirect

Like 302 but strictly preserves the HTTP method (POST stays POST). Best for: API redirects, form submissions, HSTS enforcement.

308

Permanent Redirect

Like 301 but strictly preserves the HTTP method. Best for: API endpoint migrations, POST-preserving permanent moves.
