What is the best way to redirect a domain name?

[ttvyaboydes]

Hello, good day. What should be the best method for a 301 permanent domain redirect? Should it be done through the company where the domain was purchased (e.g. Atak Domain, Metunic)? After connecting the domain to Cloudflare, should the redirect be done to another domain through the Rules section? Should the redirect be set up through the purchased server or C-panel? Or through the Httaccess file by adding any code? Or maybe by using an extra plugin for redirection? How can we best redirect our newly purchased yyy.com domain to xxx.com in a way that is SEO-friendly? Does anyone have knowledge or suggestions on this matter? Thank you.
