A permanent redirect that sends users and search engines from one URL to another. 301 redirects transfer most of the original page's ranking authority to the new URL.
A 301 redirect is an HTTP status code that indicates a permanent redirect from one URL to another. When a user or search engine crawler requests the original URL, the server responds with a 301 status code and the new URL, and the browser or bot automatically follows the redirect to the new destination. In SEO terms, a 301 redirect is the proper way to move content from one URL to another while preserving the ranking authority and link equity that the original URL has accumulated.
The importance of 301 redirects becomes most apparent during website migrations, URL restructuring, or domain changes. Without proper 301 redirects, all the SEO value built up at old URLs — backlinks, ranking history, user bookmarks — is effectively lost. Every link pointing to the old URL would lead to a 404 error, wasting the authority those links carry. A properly implemented 301 redirect preserves the vast majority of that authority, ensuring a smooth transition that maintains your search rankings.
It is worth understanding the distinction between 301 (permanent) and 302 (temporary) redirects, as using the wrong type is a common mistake. A 301 redirect tells search engines that the move is permanent, signaling them to transfer ranking authority to the new URL and eventually replace the old URL with the new one in their index. A 302 redirect, by contrast, indicates a temporary move — search engines should keep the original URL in the index and not transfer authority. Using a 302 when you mean a 301 can prevent proper authority transfer and cause indexing confusion.
The practical guidelines for 301 redirects are straightforward but important. Redirect each old URL to its most relevant equivalent on the new site — not blanket redirecting everything to the homepage, which search engines may interpret as soft 404s. Minimize redirect chains (where URL-A redirects to URL-B which redirects to URL-C) as each hop introduces latency and can dilute authority. Monitor your redirects after implementation using Google Search Console to ensure they are being followed correctly. And maintain your 301 redirects indefinitely — removing them prematurely can cause traffic and ranking losses.
