Every HTTP request returns a status code that tells browsers and search engines whether the request succeeded, redirected, or failed. A 200 OK means the page loaded normally. A 301 signals a permanent move. A 404 tells crawlers the page no longer exists. A 500 indicates a server error that may cause Google to temporarily drop the page from its index. Our HTTP Status Code Tester makes a server-side request to any URL and reports the exact status code returned—without following redirects or loading the full page—so you can quickly diagnose broken links, misconfigured redirects, server failures, and soft 404 errors that silently damage your site's health.
Why this tool is needed
The tool sends an HTTP HEAD or GET request to the specified URL and reports the response status code, response headers, and redirect destination if applicable. Unlike browser-based tools that follow redirects automatically, it captures the status at each hop, revealing intermediate 301/302/307 redirects, meta refresh tags, and server-side error codes. It distinguishes between hard 404 errors (page not found), soft 404s (page returns 200 but displays a 'not found' message), and 500-level server errors that indicate backend failures.
Role in SEO
Search engines rely on status codes to understand your site's structure. A 200 on a page that should be deleted tells Google to keep indexing outdated content. A 302 where a 301 belongs splits ranking signals between the old and new URLs. A 500 error during a crawler visit causes Googlebot to retry later, potentially demoting the page in search results. Broken links returning 404s waste crawl budget and create dead ends for users. Systematic status code auditing catches these issues across thousands of pages before they accumulate into significant SEO problems.

Frequently asked questions
What's the difference between a hard 404 and a soft 404?
A hard 404 returns an actual 404 HTTP status code, clearly telling search engines the page doesn't exist. A soft 404 returns 200 OK but displays 'page not found' content. Search engines may continue crawling soft 404s, wasting crawl budget, and may eventually treat them as 404s anyway.
Should I return 404 or 410 for deleted pages?
Use 404 if the content might return in the future or if you're unsure about the permanence of the deletion. Use 410 Gone if the content is permanently removed and will never return. Both tell search engines to stop indexing the page, but 410 is a stronger signal that the deletion is permanent.
Can 500 errors cause Google to deindex my pages?
Temporary 500 errors typically don't cause permanent deindexing—Googlebot will retry the crawl. However, persistent 500 errors over days or weeks can lead to temporary removal from the index. Extended server downtime during a crawl can also cause Google to reduce crawl frequency for your domain.
Why do some tools show 200 but my server logs show 301?
This often happens when redirects are implemented at the CDN or load balancer level. Browser-based tools may follow the redirect automatically and report the final destination as 200, while server logs record the initial response. Use a server-side status code checker to capture the true initial response.

Example output
Sample Output: URL: https://example.com/about Status: 200 OK Response Time: 180ms Content-Type: text/html; charset=UTF-8 URL: https://example.com/old-product Status: 301 Moved Permanently Location: https://example.com/products/new-product Response Time: 45ms URL: https://example.com/removed-page Status: 404 Not Found Response Time: 12ms Recommendation: If this page was permanently removed, return 410 Gone instead to signal permanent deletion to crawlers. URL: https://example.com/api/data Status: 500 Internal Server Error Response Time: 5020ms Recommendation: Server error detected. Check application logs for the root cause. Extended response time (5s) suggests a timeout or database connection issue. URL: https://example.com/soft-404-page Status: 200 OK Content: 'Sorry, this page could not be found.' Recommendation: Soft 404 detected — page returns 200 but serves not-found content. Return 404 or 410 status code instead.
Best practices
- Audit status codes for all URLs in your sitemap at least quarterly to catch newly broken pages
- Ensure pages that permanently moved return 301, not 302, to consolidate ranking signals to the new URL
- Fix soft 404s by returning actual 404 or 410 status codes for deleted content rather than serving a 'not found' page with 200
- Monitor 500-level errors in server logs and set up alerts to detect backend failures before they impact indexing
- Use 410 Gone instead of 404 for content that has been permanently removed and will never return
- Test status codes with and without following redirects to distinguish between the initial response and final destination
