I have developed a website which is like a web appliation. a user has to login to visit next pages. I want only the login page to be found out by google. The SEO guidelines that I got on internet are more for blogs or websites which has many open pages.

I am not getting a clue how to proceed. If i search my website name on google, the description still shows the goDaddy page stating - click here to find out how to purchase this domain name.

Need help desparately.
