301 Redirect
A 301 redirect is a permanent HTTP redirect that sends both users and search engine crawlers from one URL to another. The “301” refers to the HTTP status code the server returns. It tells browsers and search engines that the original URL has moved permanently to the new destination.
301 redirects are the most SEO-safe type of redirect because they pass the majority of link equity from the old URL to the new one. When you have backlinks pointing to an old URL and you redirect it with a 301, those links effectively point to the new destination.
Common situations requiring 301 redirects include changing URL slugs after publishing, migrating from HTTP to HTTPS, consolidating duplicate pages, redesigning site architecture with new URL structures, merging two websites or domains, and retiring old pages while wanting to preserve their link equity.
A 301 redirect is implemented at the server level, in your .htaccess file for Apache servers, in nginx configuration for Nginx servers, or through your CMS settings in platforms like WordPress.
Avoid redirect chains whenever possible. If Page A 301s to Page B and Page B 301s to Page C, some equity is lost at each step and page load speed suffers. Audit your redirects periodically and update chains to point directly to the final destination.
