Enter up to 100 URLs (Each URL must be on separate line)

Every time a browser or search engine requests a page, the server answers with an HTTP status code: 200 means success, 301 means permanently moved, 404 means not found, and 500 means a server error. A Server Status Checker fetches any URL and reports the exact status code returned, along with the redirect chain when one exists, so you see precisely what crawlers see.
For SEO, status codes are critical signals. A page that should rank but returns a 404 error is invisible to search engines, while a 500 error during a Google crawl can cause pages to drop from the index. Misconfigured 301 redirects leak link equity or trap visitors in redirect loops, and soft 404s waste crawl budget on pages that will never rank. Site owners often discover these problems only after traffic has already fallen, which is why proactive checking matters far more than reactive firefighting. Webmasters use status checks after site migrations, during technical SEO audits, and when diagnosing sudden ranking drops.
A 301 is a permanent redirect that passes nearly all link equity to the new URL — use it for moved pages and domain changes. A 302 is temporary and does not reliably pass ranking value. For SEO, moved content should almost always use a 301.
A soft 404 happens when a page returns a 200 success code but contains little or no real content, like an empty search results page. Google treats these as not-found pages. Either return a proper 404 or 410 status, or add genuine, useful content to the page.
Run a check after every migration, redesign, or bulk URL change, and include status audits in quarterly technical SEO reviews. If rankings drop suddenly, checking your key pages status codes is one of the first diagnostics to run.
500 errors usually come from server-side problems: misconfigured files, exhausted resources, broken plugins, or code errors. They are urgent because crawlers may de-index pages that repeatedly fail. Contact your hosting provider if the cause is not obvious.
