HTTP Status codes are three-digit numbers returned by servers that indicate the status of a web element.
It is important to understand that the first digit of each three-digit status code begins with one of five numbers, 1 through 5. From the 100s through the 500s, status codes fall into the following categories:
• 100s - Informational: Request has been received and the process is continuing.
• 200s - Success: Request was received and processed successfully.
• 300s - Redirection: Request has been received, but needs to perform an additional step to complete the request.
• 400s - Client Error: Request was made by the client, but the page is not valid.
• 500s - Server Error: Valid request was made by the client, but the server failed to complete the request.
While there are many different HTTP status codes, most are not directly important to SEO.
