What is an HTTP header checker?

An HTTP header checker shows the response details a server sends when a browser or search engine requests a page.

Why HTTP status codes matter

Status codes help you find redirects, broken pages, server errors, blocked pages, and technical SEO issues that can affect crawling and indexing.

Common HTTP status codes

200 means the page is working. 301 or 302 means the page redirects. 404 means not found. 500 means a server error.
