301 redirects in WordPress – Redirects to Maintain SEO & Inbound Links
It’s highly recommended to set up 301 redirects in WordPress when you change the URL (permalinks) of your posts and pages or move your website from one domain to another. If you are changing the URL / domain of your WordPress website, you need to plan carefully so that you don’t loose any of your existing traffic and SEO elements for existing post/pages for your old domain.
