Does blocking countries from your site make a difference to how you rank on search engines? Say for example I only allow traffic from US, UK, CA, AU Will that have any impact on how my site is ranked?
I don't think it will affect the search engine rusults. If it does, then I will just block all other countries aside from the country I target, then rank #1.
Well i think your site will rank higher to the country you've been choose but I also guess that you will still rank to other country even though it is blocked.
It is not sure that you will get ranked in the countries you are allowing. It might be the reason that you will not get enough traffic as you have blocked some countries. But i can't find the reason why you want to ban any country for your website?
