~90% of my views from the US?

Google.com is international, but users usually get local search results first. I`d say try to market for specific countries you need, like .com.au ...

So your primary concern is getting traffic from other countries aside from the US. Users actually get a local search result – one will get results related to one’s region. According to Google, if you have a TLD of .com, .org or .net or any domain that is not that country specific, there is a better chance of ranking to territories (.au for Australia and .ca for Canada).

There are several things that you can do:

1. Use the Geo Targetting in Webmaster Tools to set the location. In your Google Webmaster Tools account, select the site, go to Configuration – Settings – Geographical Target and choose the country that you want to target visitors from.

2. Provide relevant content. This is one of the most important factors in generating targeted traffic. You content should be informative, accurate, readable and understandable. If you’re targeting all English-speaking countries, your content should be relevant to those areas and should not be like writing about services offered in China.

3. Get targeted traffic by guest blogging or posting relevant content on forum threads with high traffic; participating on social media sites to make your unique content viral; affiliate programs including PPC on search engines like Google - if the advertisement is properly optimized, you can get good quality of traffic; Press Releases, etc. For high traffic, always make sure that your contents are useful to the readers and your site is easy to navigate.
