Welcome to the Q&A Forum

So what, list all countries in Asia as rel alternate tags + english language? that sounds terrible.

I want to serve the same content to different continent. Serving asian customers from USA data center is just slow and it takes a lot of time for them to load the site. On the other hand, we have an asian datacenter so I want to handle the entire continent from that datacenter. At this point, we cannot use the same domain (.com). So I wanted to clone the main site and redirect all asian traffic to it. Just wondering how to do this...

I want to duplicate the main site.com and service Asia from a different datacenter. The content is the same but the domain will be site.asia. How to properly tag to avoid duplicate content?

Implementing those right away, hope it will work

I've done that, the country is declared in GWT, google fetches it, there are quality links from authoritive websites that already point to those pages, not thousands but still few. I've read all those articles long ago. I was hoping someone to take a look at the site meta and/or suggest some actions.

I've done everything I can think of to set internationalization between three domains but Google keeps showing my .com results in Spain where .es results should be displayed. The site is siteground.com siteground.es and sitegorund.co.uk. I've used alternate tags which I think are set correctly, siteground.co.uk ranks pretty well in the UK search but in Spain - still can't get .es results and that's been 3 months already.
