What is HTTP Status Code Checker?

An HTTP status code checker reports the three-digit code a server returns for a URL — 200 (OK), 301 (moved permanently), 404 (not found), 500 (server error) and the rest. Every web request gets one, and it's the server's one-word verdict on what happened, invisible to normal visitors but decisive for SEO, monitoring and debugging.

The codes group by first digit: 2xx success, 3xx redirects, 4xx client errors (the request was wrong — 404, 403), 5xx server errors (the server failed — 500, 503). Knowing which a URL returns turns "the page is broken" into a specific, fixable diagnosis.

About the HTTP Status Code Checker

Enter a URL and read its status code with a plain explanation of what it means.

Why it matters per code: 200 — healthy, the page works; 301 vs 302 — permanent (passes SEO value) versus temporary (doesn't) redirects, a distinction that silently costs rankings when wrong; 404/410 — genuinely missing (correct for deleted content) versus the dreaded soft-404 (a "not found" page returning 200, confusing crawlers into indexing empty pages); 403 — forbidden (permissions/firewall blocking); 500/503 — server broken/overloaded (the emergency codes). SEO audits live here: pages returning wrong codes leak crawl budget and rankings.

Uses: verifying redirects work as intended, confirming deleted pages return real 404s (not soft-200s), catching server errors before visitors do, and checking that a "fixed" page actually returns 200 now. For multi-hop redirect chains, our Redirect Checker traces the whole path; for full response detail (headers, caching), the HTTP Headers Checker goes deeper. This gives the one number that starts every diagnosis.

Frequently Asked Questions

2xx success, 3xx redirect, 4xx client error (bad request — 404, 403), 5xx server error (server failed — 500, 503). The first digit tells you the category; the full code the specifics.

A "page not found" that returns status 200 (OK) instead of 404 — the CMS serves a not-found PAGE with a success code. It confuses crawlers into indexing empty pages. Genuine missing content must return an actual 404/410.

301 (permanent) for real moves — it passes ranking signals to the new URL. 302 (temporary) tells Google to keep the old URL indexed. A permanent move mistakenly served as 302 quietly withholds SEO value.

Forbidden — the server understood the request but refuses it, usually permissions, authentication, or a firewall/security rule blocking access. Different from 404 (doesn't exist); 403 means "exists but you can't have it".

500 = the server hit an unhandled error (application bug, misconfiguration, database failure). 503 = service unavailable (overloaded, or in maintenance). Both are server-side emergencies — check logs; visitors see a broken site until resolved.
