Hi Ratnesh,
A lot of things involve in ranking the pages by Google, but to get started have a look at this link
http://www.googleguide.com/improving_pagerank.html.
I feel 3 things which could improve the ranking is
1) Have useful content neatly organized. Use meta-tags to provide more info to search engines.
2) Start socializing - meaning create a blog and/or a page on Google plus and Facebook and keep posting some updates. Ask your friends to subscribe, continue to build huge circle/subscribers including your friends and their friends and so on...
3) have patience. It will take time to improve rank of web page. you should try for a month and give up!! it will take some time to improve rank.
This is just my opinion. As i said there are lot of factors involving in ranking pages by Google, any way to get more info, Google for SEO (Search Engine Optimization).

Vinay
