So we've had some issues come up recently regarding Geo-blocking/redirecting/targeting our traffic and how doing so effects Search Engine ratings.

My question is simple, what affect, if any, does geo-blocking/redirecting/targeting have on search engine ratins? Do SE's like google and bing and such penalize you for blocking/redirecting/targeting access to your servers (at the webserver level) based on country?

IE. If we block/redirect China, India, Philippines and Thailand traffic from accessing our servers, do we get penalized for this?

When answering, please provide some technical data that proves or disproves the theory.

Thanks
