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.

❓ 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.
