What are HTTP status codes?
Every page on your website will return a status code when a browser or search engine attempts to access it. These HTTP status codes essentially tell the machine trying to access a URL whether the page is active and live (that is, “valid”), whether the page has been moved and requires a redirect to a different URL, or if the page associated with that URL cannot be found (an “invalid” page; for example, one with a 404 status code).
