How to get traffic from a particular Geographical region?

That could be the case. Why is a company outside India using a .in domain ext.? Also it could be because your backlinks could be one India based sites. Also your site must be ranking in Google.co.in, which is why you are getting more traffic from India.

You’d better switch to a generic TLD, because Google ranks your site in local search higher than it does in universal search. The thing is that your TLD is associated with the particular geographic region, and that’s why your search engine traffic comes from this region too. You may also remove your location information (map, address) from site’s pages (if there is any).

Also you may set up a geographic target in GWT to be absolutely sure your page is associated with the target country. Go to GWT homepage, click your site -> Site configuration -> Settings -> Geographic target, and then specify the country you’d like to target. However, if you specify just one country, you will most probably lose traffic from other locations.

If there are any ‘local’ keywords you’re optimizing the website for, just get rid of them and add some keywords that refer to the target countries instead.

What Google also considers as one of the most important geotargeting factors is where the inbound links are coming from, so if you manage to add quality links from sites associated with your target country to your backlink profile, that will be a good sign for Google and your site is more likely to appear in search results in this very country.

If you want North American traffic, I would get a .com or some other non-region specific TLD. I would also probably host the site in North America as well.

Yeah, just have all your content rewritten, create a "new version" of your site, and put it on a country specific (the country that you're targeting) domain name.

You can do this as many times as you like, for as many countries as needed. It actually also adds a bit of a "global edge" to your business, and makes you look "bigger" than you probably in fact are.
