How do I check an HTTP status code?

Enter any URL in the ToollLive HTTP Status Code Checker and click Check. The tool fetches the URL via a CORS proxy and returns the live HTTP status code, response headers, server info and redirect chain.

What does HTTP 301 vs 302 mean?

HTTP 301 (Moved Permanently) tells search engines the page has permanently moved — they should update their index and pass link equity to the new URL. HTTP 302 (Found/Temporary Redirect) means the move is temporary — search engines keep the original URL in index and do not transfer link equity.

Why is my URL returning a 404 error?

A 404 error means the server cannot find the requested page. Causes include: the URL was deleted, mistyped, or the page was moved without setting up a redirect. 404 errors waste crawl budget and lose link equity — set up 301 redirects to the correct URL.

What is the difference between 301 and 308 redirects?

HTTP 301 (Moved Permanently) allows search engines and browsers to change the request method from POST to GET on redirect. HTTP 308 (Permanent Redirect) preserves the original HTTP method — a POST request must remain a POST on the redirect destination. Both pass link equity.

Frequently Asked Questions

What is an HTTP status code?

An HTTP status code is a 3-digit number returned by a web server indicating the result of a request. 2xx means success, 3xx means redirect, 4xx means client error (like 404 Not Found), and 5xx means server error. Status codes are critical for SEO — 4xx and 5xx pages waste crawl budget and lose link equity.

What is the difference between 301 and 302 redirects?

A 301 (Moved Permanently) tells search engines the page has permanently moved. Google passes ~100% of link equity to the destination and updates its index. A 302 (Found / Temporary Redirect) is temporary — Google keeps the original URL in index and does NOT transfer link equity. Use 301 for permanent changes, 302 only for genuine temporary moves.

Why is 404 bad for SEO?

404 errors waste your crawl budget (Googlebot visits dead pages instead of live ones), lose any link equity pointing to those URLs, and create poor user experience. Fix 404s by setting up 301 redirects to the closest relevant live page, or restoring the page if it was accidentally deleted.

What does HTTP 200 mean?

HTTP 200 OK means the server successfully processed the request and returned the requested resource. This is the normal, healthy status for any page you want indexed by search engines. All your key pages should return 200.

What is a soft 404?

A soft 404 is when a page returns HTTP 200 but shows a "not found" or error message in the content. Google detects these and treats them like real 404s. Common causes: CMS pages with no content, search pages with no results, or error pages that return 200 by mistake. Fix by returning a proper 404 status code on error pages.
