Як використовувати перевірку CDN

An HTTP status code is a 3-digit number returned by a web server to indicate the result of a request. Common status codes include: status code 200 (OK — the page loaded successfully), status code 301/302 (redirect), status code 400 (Bad Request), status code 401 (Unauthorized), status code 403 (Forbidden), and status code 500 (Internal Server Error).

Status code 200 means the request was successful — the server returned the page without any errors. This is the ideal status code for any URL you want indexed by search engines. Use this 200 status code checker to confirm that all your important pages are returning the correct HTTP response.

Status code 401 (Unauthorized) means the request requires authentication — the user needs to log in to access the resource. Status code 403 (Forbidden) means the server understood the request but refuses to authorize it, even with valid credentials. Both indicate access restrictions and can affect SEO if applied to pages that should be publicly available.

Status code 400 (Bad Request) is a client-side error — it usually means the URL is malformed or the server cannot interpret the request. Status code 500 (Internal Server Error) is a server-side error indicating something went wrong on the server. Both should be fixed promptly as they prevent users (and search engine bots) from accessing the page.

Our bulk status code checker supports up to 10 URLs per batch. Simply paste one URL per line and click "Check HTTP Status Code". For larger lists, split them into groups of 10. You can also export all status code results to CSV for further analysis.

Using an http status code checker online is essential for SEO audits. Broken pages returning status code 400, 401, 403, or 500 can harm your rankings and user experience. A website status code checker helps you quickly identify which URLs are healthy (status code 200), which are redirecting, and which have errors — so you can fix issues before they impact your search performance.
