It’s generally not as critical as with a domain move. For one, if you implement HSTS on the site (and maybe have it added to the pre-load lists), then users will go directly to the HTTPS version, they won’t even see the redirect. Also, if it’s just http -> https, then any redirect there won’t require a separate DNS lookup (which tends to slow things down a tiny bit, especially on mobile). That said, it’s always a good practice to link to the final URL instead of a known redirecting one.<\/p><\/blockquote>\n
