Where to Submit Sub-Domains?

Hi
I know it is a noob question but I am still confused to decide where and how to submit sub-domains.
I have a website (market palace) that has subdomains. For example, the website is www(dot)abc(dot)com (Already submitted to Google and also indexed by Google) and sub-domains such as
www(dot)china(dot)abc(dot)com
www(dot)uk(dot)abc(dot)com
www(dot)australia(dot)abc(dot)com

So, I would like to know that where I will submit these subdomains so, Google will index them for the particular region. Because the main website domain www(dot)abc(dot)com is already submitted to Google by GWT.
Any suggestion or advice would be much appreciated.
Thank You

 

Create the subdomain in Google as with the domain name. And verify it the same way. Treat it as a separate site.

What about regions:
"Google Search returns the most relevant and useful sites for a user. Because of this, search results can differ between a user in Ireland and a user in France.

If your site has a generic top-level domain, such as .com or .org, you can help us determine which countries are most important to you. If your site has a country-coded top-level domain (such as .ie or .fr) it is already associated with a geographic region (in this example, Ireland or France). If you use a country-coded domain, you won't be able to specify a geographic location. You can specify a target country in the International Targeting report.

Set a country target

1. On the International Targeting report, click the Country tab.
2. Check the Geographic target checkbox and choose your country target. If you want to ensure that your site is not associated with any country or region, select Unlisted in the drop-down list.

This setting is only for geographic data. If you're targeting users in different locations—for example, if you have a site in French that you want users in France, Canada, and Mali to read—don't use this tool to set France as a geographic target. A good example of where it would be useful is for a restaurant website: if the restaurant is in Canada, it's probably not of interest to folks in France. But if your content is in French and is of interest to people in multiple countries/regions, it's probably better not to restrict it."

 

Thank you, Host Service, for the complete answer. I got the answer.

Thanks again for the answer.

 

I have seen several time and agree with that statement - you can use your subdomains with article submission and target them for less competitive keywords.

 

I agree with you but my query was different and you solved that.

 

Sub-domains are considered as separate domains. If you want to submit them to google then you have to do it through separate xml sitemaps through your webmasters tool account.

 

Yes, Sitemap and Robots.txt file is already submitted.
