HTTP Status Code Checker – Free Bulk URL & Internal Link Checking Tool

An HTTP Status Code Checker is a helpful online tool designed for website owners, SEO specialists, developers, and digital marketers who want to make sure their websites are working properly. Whenever a browser or search engine visits a webpage, the server responds with an HTTP status code. This code explains whether the request was successful, redirected somewhere else, or failed due to an error.

Our Free HTTP Status Code Checker allows you to check the response codes of single URLs, bulk URL lists (up to 100 URLs), and internal links. It provides detailed insights such as redirect information, response time, server behavior, and headers. This helps you quickly identify and fix problems that could affect your website’s performance, search engine rankings, and user experience.

What Is an HTTP Status Code?

An HTTP status code is a numeric message returned by a server when someone requests a webpage. It tells the browser or search engine what happened while trying to load that page.

For example:

• 200 OK – The page loaded successfully
• 301 Moved Permanently – The page has been permanently redirected
• 404 Not Found – The page does not exist
• 500 Internal Server Error – The server encountered a problem

Search engines like Google rely heavily on these status codes to understand your website. If the wrong codes are returned, it may cause indexing issues, ranking drops, or loss of traffic.

What Is the HTTP Status Code Checker Tool?

The HTTP Status Code Checker is a free online tool that tests the HTTP response returned by a server for any URL. It supports both HTTP and HTTPS and delivers quick and reliable results.

With this tool, you can:

• Confirm whether a webpage is active, redirected, or broken
• Identify redirect chains and loops
• Detect SEO-related issues such as 404 or server errors
• Test URLs during development, migration, or performance checks

This makes the tool extremely useful for SEO audits, troubleshooting website errors, and testing site performance.

Key Features of the HTTP Status Code Checker

✔ Bulk URL Checker (Up to 100 URLs)

You can check up to 100 URLs at the same time. This is especially useful for large websites, blog audits, and SEO campaigns where multiple pages need to be reviewed quickly.

✔ Internal Link Checker

Simply enter a single webpage URL, and the tool will scan and extract all internal links from that page. It will then check their status codes automatically, helping you find broken links that may affect SEO and user experience.

✔ Redirect Analysis

The tool provides complete redirect details, including:

• Total number of redirects
• Redirect chains such as 301, 302, or 308
• Final destination URL

This helps you avoid unnecessary redirects or loops that can slow down your website.

✔ Response Time & Performance Tracking

Each URL report includes response time, allowing you to identify slow pages that may negatively impact user satisfaction and Core Web Vitals.

✔ Detailed Request and Response Information

You can view complete HTTP request and response headers, which helps developers and technical SEO professionals understand server behavior more clearly.

Types of HTTP Status Codes

HTTP status codes are grouped into five main categories:

1xx – Informational Responses

These indicate that the request has been received and is still being processed.

Examples:
 100 Continue
 101 Switching Protocols
 102 Processing

2xx – Successful Responses

These confirm that the request was completed successfully.

Examples:
 200 OK
 201 Created
 202 Accepted
 203 Non-Authoritative Information

3xx – Redirection Responses

These indicate that the requested resource has moved to another location.

Examples:
 301 Moved Permanently
 302 Found
 303 See Other
 304 Not Modified

4xx – Client Error Responses

These occur when the request is invalid or the requested page cannot be found.

Examples:
 400 Bad Request
 401 Unauthorized
 403 Forbidden
 404 Not Found

5xx – Server Error Responses

These indicate that the server failed to complete a valid request.

Examples:
 500 Internal Server Error
 501 Not Implemented
 502 Bad Gateway
 503 Service Unavailable
 504 Gateway Timeout

Why Checking HTTP Status Codes Is Important

Regularly monitoring HTTP status codes helps you:

• Detect broken pages before visitors notice them
• Improve website crawlability for search engines
• Prevent ranking losses caused by errors
• Fix redirect and server problems quickly
• Improve overall site reliability and performance

If your website contains too many broken links or server errors, search engines may reduce crawling frequency or lower rankings.

The Role of HTTP Status Codes in SEO

HTTP status codes play a major role in how search engines understand and rank your website. They help search engines decide:

• Whether a page should be indexed
• Whether link authority should be passed
• How redirects should be handled

For example:

• 301 redirects should be used when permanently changing URLs to maintain SEO value
• 404 errors should be fixed or redirected properly
• 5xx errors should be resolved quickly because they block access to your website

Our HTTP Status Code Checker helps you identify and fix these issues before they impact your search rankings.
