Hey, have you ever tried moving your site to a brand new domain? I wonder if 301 really keeps rankings.
E.g. you have your current-domain.com site which ranks on page #1 for bunch of terms. You move your site to brand-new-domain.com, exactly the same content, everything the same, 301 old domain to new domain per URL.
Do you immediatelly get the same great rankings on page #1 for the brand new domain?
