A 301 redirect is a permanent redirect that informs search engines and browsers that a page has been permanently moved to a new location. It passes most of the original page's ranking power to the new URL, ensuring that users and search engines can access the new page easily.
You should use a 301 redirect in various situations, such as:
- When you have merged two websites and want to redirect the traffic from the old site to the new one.
- When you have changed the URL structure of your website, and the old URLs are no longer valid. Implementing 301 redirects helps maintain SEO rankings and provide a seamless user experience.
- When you have renamed a webpage or an entire website, and you want to redirect users and search engines to the new URL.
- When you have multiple versions of your website (with and without www or http/https) and you want to redirect all variations to the preferred version.
- When you have deleted a webpage or an entire website, and you want to redirect users to a relevant page instead of showing an error (404) page.
It is important to implement 301 redirects correctly to maintain SEO rankings and avoid negative impacts on user experience.
