Adding a domain to a project will now also suggest adding its
wwwcounterpart. This ensures visitors can always access your site, regardless of whether they type
wwwwhen entering the domain, or not.
wwwdomain guarantees that the Vercel Edge Network can reliably and securely route incoming traffic as quickly as possible, so redirecting non-
wwwdomain is recommended. Redirecting the other way works too if you prefer a cleaner URL address.
Existing domains are not affected by this change, but we recommend ensuring that your project already has a
wwwredirect in place.
