HTTP Status Code Checker – Check URL Response Codes, Errors & Redirects

The HTTP Status Code Checker helps you instantly verify how a web server responds to a request. It shows HTTP response codes, redirect behavior, headers, and error states so you can quickly identify broken pages, misconfigured redirects, or server issues.

This tool is essential for SEO audits, website migrations, API testing, performance monitoring, and debugging web infrastructure.

What Is an HTTP Status Code?

An HTTP status code is a three-digit response sent by a server to indicate the outcome of a request made by a browser, bot, or API client.

Common examples include:

• 200 OK – Page loaded successfully
• 301 Moved Permanently – Permanent redirect
• 302 Found – Temporary redirect
• 404 Not Found – Page doesn’t exist
• 500 Internal Server Error – Server-side issue

Search engines rely heavily on these codes to decide indexing, crawling, and ranking behavior.

Why Use an HTTP Status Code Checker?

Status codes directly impact SEO, user experience, and system reliability.

Use this tool to:

• Detect broken links (404, 410)
• Identify redirect issues (301 vs 302)
• Track full redirect chains
• Debug server errors (5xx)

HTTP Status Code Categories Explained

2xx – Success

• 200 OK – Page loads normally
• 204 No Content – No content returned

✅ Ideal for pages you want indexed.

3xx – Redirection

• 301 – Permanent redirect (SEO-friendly)
• 302 / 307 – Temporary redirect
• 308 – Permanent redirect (method preserved)

⚠ Too many redirects can harm SEO and performance.

4xx – Client Errors

• 400 – Bad request
• 401 / 403 – Unauthorized or forbidden
• 404 – Page not found
• 410 – Page permanently removed

❌ Pages returning 4xx errors are not indexed by search engines.

5xx – Server Errors

• 500 – Internal server error
• 502 – Bad gateway
• 503 – Service unavailable
• 504 – Gateway timeout

🚨 Persistent 5xx errors can cause deindexing.
