301/302 Redirect Checker

Send a real request to any URL and verify its live HTTP status, whether it redirects, and where it lands. Browser security limits are reported transparently instead of guessed.

● 100% Free Tool

Configure Optimization Parameters

The tool sends one live request from your browser. Sites that block cross-origin reads cannot be inspected and the tool will say so instead of guessing.

How To Use The 301/302 Redirect Checker

1

Enter the Target URL

Paste the full address you want audited, including http:// or https://.

2

Run the Live Check

Click Generate. The tool sends a real request from your browser and reports the verified status, final URL, and whether a redirect occurred.

3

Read the Transparency Notes

If browser CORS rules hid parts of the response, those values are marked UNKNOWN — never fabricated. Use server-side tooling for hop-by-hop codes on blocked targets.

Aesthetic & Functional Benefits

Real Requests, Real Answers

Every reported value comes from an actual network response — never from guesswork or cached assumptions.

Catch Redirect Mistakes Early

Confirm old URLs land on their intended replacement so you avoid chains, loops, and lost link equity after migrations.

Transparent About Limits

When browsers hide information (CORS/opaque responses), the report says UNKNOWN instead of pretending to know.

Understand Redirect Codes

Includes a plain-language reference distinguishing 301, 302, 303, 307, and 308 behaviour.

Common Mistakes & How to Avoid Them

Ensure your implementation is search-engine compliant by avoiding these frequent validation traps.

⚠️ Trusting Tools That Never Really Checked

Many checkers print plausible-looking chains even when every request failed. This tool refuses to fabricate data.

Correction: Follow the recommended input formats and copy templates within this local browser sandbox.

⚠️ Mixing Up 302 and 301

Using temporary redirects for permanent moves delays re-indexing because search engines keep re-crawling the old URL.

⚠️ Redirecting Everything to the Homepage

Pointing deleted pages at the root instead of a relevant equivalent creates soft-404 signals and frustrates visitors.

Frequently Asked Questions (FAQ)

Common questions and specifications regarding correct operation of the free 301/302 Redirect Checker utility.

Browsers do not expose intermediate hops to JavaScript. fetch() either follows redirects silently or returns a fully opaque response, hiding status codes and Location headers. Hop-by-hop chains require server-side tooling.
UNKNOWN is printed whenever browser security prevented reading a value. It means the tool genuinely could not verify that detail — it never fills gaps with guesses.
Most websites send no Access-Control-Allow-Origin header, which blocks cross-origin reads from browsers. That failure means the check could not be performed, not that the site is broken.
Not reliably. Browsers abort silently when too many redirects occur and surface the same error as a CORS failure, so the loop cannot be distinguished honestly. Server-side checkers are required for loop detection.
Both are permanent redirects. 308 additionally preserves the original HTTP method, while 301 may switch POST requests to GET.
Permanent redirects (301/308) consolidate most ranking signals to the destination over time, while temporary ones (302/307) keep them with the original URL.
No. The request goes straight from your browser to the target site. Nothing is proxied or logged by SEOKit.
