ℹ️ About HTTP Status Codes List

The HTTP Status Codes List is a comprehensive reference for the three-digit codes returned by web servers to indicate the outcome of an HTTP request. These codes are the "language" of the web, allowing servers to communicate success, redirection requirements, client-side errors, or server-side failures to browsers and crawlers.

Understanding these codes is fundamental for SEO troubleshooting, API development, and general web administration. For example, a 301 Moved Permanently is critical for preserving search rankings during a site migration, while a 404 Not Found identifies broken links that frustrate users. This tool allows you to either browse the full list by category or quickly search for a specific code to understand its exact meaning and implications.

📖 How to use HTTP Status Codes List

  3. 3. Browse the categorized list to see the most common codes in the 1xx to 5xx ranges.
  4. 4. Use the 'Meaning' field to understand what the code tells the browser to do next.

Frequently Asked Questions

What is the difference between a 4xx and a 5xx error?

4xx codes indicate client-side errors (e.g., the browser requested a page that doesn't exist), while 5xx codes indicate server-side errors (e.g., the server crashed while trying to process a valid request).

Why is a 301 redirect better for SEO than a 302?

A 301 indicates a permanent move and passes 'link equity' to the new URL, while a 302 is seen as temporary and does not typically transfer ranking power.

What does a 429 status code mean?

429 stands for 'Too Many Requests.' It is used for rate-limiting, telling the client they have sent too many requests in a given amount of time.
