Welcome to the Q&A Forum

I think if you correct those things, build good quality incoming links and post content which users will enjoy reading then your site should start to improve in the rankings within a few weeks.

Well two things you can do is: 1. Make the domain in google webmaster tools US based. 2. Buy a .com domain and target it in the US market. Overall it is not easy to target GEO specific domains to other areas I see it with .com.au domains they work great in AU yet ranking them in India is hard. so in the end it may be worth buying a .com and making a micro site and then drive traffic back to the .co.in
