Why most website traffic comes from india ?

I also want to know why

faii acy most traffic will not come from china because china speaks Chinese language.

Because the interwebs are cheap in India.

I've also noticed that that most of the visitors on my website arrives from India. This would be very beneficial for any entrepreneur to point these country like India and chine for having more growth...

There are two countries in the world with 1 Billion + populations, India and China. Both are developing nations, and both have limited online earning opportunities. Residents of both of these countries are actively seeking out ways to make money. India, with a technological headstart, presently accounts for the lion's share of these people. But it won't be like that for long. I suspect that a year from now you or someone like you will be asking: "Why most website traffic comes from China?"

Because most of internet marketer or internet marketing companies in India...

I think the main core business in India is IT, mainly in Internet.

There are lots of people in India, about 1,2 billion :) If You would like to target the organic traffic from google, You will need to point the country in Google Webmaster Tool.
