HTTP status codes communicate how a server responds to a request from a browser or search engine. They help identify successful page loads, redirects, client errors, and server errors. Understanding these codes helps website owners maintain performance, improve user experience, and support search engine visibility.

A 200 OK status code indicates that a page has loaded successfully and the server processed the request correctly. This is the ideal response code for pages that should be indexed and accessed by users and search engines.

A 301 status code indicates a permanent redirect from one URL to another. It is commonly used when pages are moved or URLs change. Properly implemented 301 redirects help preserve SEO value and guide users to the correct destination.

A 404 Not Found status code means the requested page cannot be located on the server. This can occur when a page has been deleted, moved without a redirect, or the URL was entered incorrectly. Excessive 404 errors can negatively impact user experience and website performance.

A 500 Internal Server Error indicates that the server encountered an unexpected problem while processing the request. This error often requires technical investigation because it can prevent users and search engines from accessing important pages.

You should regularly monitor important website pages, especially after website updates, migrations, redesigns, or SEO changes. Routine checks help identify broken links, redirect issues, and server problems before they affect traffic or conversions.

Yes. Search engines use HTTP status codes to understand whether pages should be crawled, indexed, redirected, or removed from search results. Incorrect status codes can lead to indexing issues, lost rankings, and reduced organic traffic.
