Check URL status codes and final response details
The checker follows a limited number of public HTTP redirects and reports the final status, destination URL, elapsed fetch time, response content type and selected headers. This is useful when a browser appears to load a page normally but crawlers or integrations are receiving a different response path.
Common SEO debugging cases include an old URL returning 200 instead of redirecting, a migrated page returning 404, an HTTP URL taking multiple hops before HTTPS or a final response carrying an unexpected X-Robots-Tag.
HTTPS status checker: test a secure URL response
If your task is specifically to check an HTTPS status, enter the full secure URL beginning with https://. Toolmera tests the public HTTPS response and shows the returned status code, final URL, redirect hops, response time and selected response headers so you can confirm whether the secure page ends in 200 OK, redirects elsewhere or returns an error.
This is useful for checks such as “is this HTTPS URL returning 200?”, “does the secure page redirect?”, or “what status does the final HTTPS destination return?”. For certificate-focused questions such as HTTPS availability and HSTS behavior, use the separate SSL Checker; this page is focused on the HTTP status and response path.
What 200, 3xx, 4xx and 5xx mean in practice
A 2xx status indicates a successful HTTP request. 3xx statuses signal redirection, 4xx statuses describe client-side request problems such as 404 Not Found, and 5xx statuses indicate server-side failures. The exact meaning depends on the specific status code.
For SEO, the distinction matters because search engines treat a working content URL, a permanent redirect and a missing page differently. A status checker is therefore one of the fastest ways to verify a migration or diagnose a crawl error.
Response time is a network diagnostic, not Core Web Vitals
The elapsed time shown here measures the Toolmera edge request and any redirects until the final response is read. It is not the same as browser rendering performance, Largest Contentful Paint or Interaction to Next Paint.
Use the timing as a quick comparison signal for slow responses or redirect chains, then use a dedicated browser performance test when you need rendering and Core Web Vitals data.
