I don't think there is really a way to o that. All I know is gmail now detect those mails and throws them in the spam folder so that you do not see them unless you choose to. If there is a way to do it, I will love to know too.

I think what really matters is where most of your hosting company servers are located. That is why some people check where most of their traffic is coming from and choose hosting companies that have many servers and are quite fast around that region. Although, there are some great hosting companies like SiteGround that generally have FAST servers in most regions.

3 now, and probably counting.

I'll definitely go for Yoast SEO.
