What does an HTTP status checker do?
An HTTP status checker requests a URL and reports the response status code — such as 200 OK, 301 redirect, 404 not found or 500 server error — along with the redirect chain it followed. SiteGuard Monitor's checker shows the status alongside SSL, DNS, email security and headers in one explainable 0-100 risk score.
A page can look fine yet return the wrong status code — a soft 404, a broken redirect chain or an intermittent 500. This free HTTP status checker shows exactly what a URL returns, then runs a full scan so you see it in context.
Why status codes matter
Status codes are how servers, browsers and search engines understand a page. A redirect loop, an unexpected 404 or a 5xx error can quietly hurt traffic and SEO long before anyone notices something looks off in the browser.
- Redirect chains and loops slow pages and confuse crawlers
- A soft 404 returning 200 wastes crawl budget
- Intermittent 5xx errors point to server trouble
What this HTTP checker shows
- The final HTTP status code
- The full redirect chain (301, 302 and more)
- Whether the URL resolves over HTTP and HTTPS
- Response timing for the request
Status in the bigger picture
A status code is one signal of overall health. This tool runs a full free scan, so the response appears next to the SSL certificate, DNS records, email security and security headers — combined into a single 0-100 risk score.
Turn a one-off check into uptime monitoring
Add a domain to SiteGuard Monitor and the status is checked continuously, not just once. If a URL starts returning errors or breaks, you get an instant email and Discord alert, with uptime history captured in branded client reports.
- Continuous HTTP/HTTPS status monitoring
- Instant alerts on error codes and downtime
- Uptime history included in monthly reports
A passive, read-only request
An HTTP status check is a single read-only request — the same thing a browser does when it loads a page. SiteGuard performs no load testing or aggressive scanning; it simply observes the response.
