/θri oʊ wʌn ˌridəˈrɛkt/
An HTTP response status code used for permanent redirection from an old URL to the new URL.
301 redirects are important when a company is renamed or rebranded. If the redirect is not in place, a user may reach the old URL by mistake, resulting in a 404 not found error. 301 redirects prevent declines in visitor traffic and product views and prevents loss of search engine optimization (SEO).
