I have developed a website which is like a web application.  A user must log-in to visit/view other pages. I want the login page to be the only one found by Google.  The SEO guidelines that I found online are more for blogs or websites which have many open pages.I'm not sure how to proceed.  A search for my website name on Google shows the description on the GoDaddy page stating click here to find out how to purchase this domain name.

If your website requires users to login to access the content, then nothing beyond the log-in form will be accessible to Google and other search engines (unless you mistakenly expose it). They can't complete authentication, but you may want to consider a more restrictive approach.In terms of the domain result in Google still showing the GoDaddy place-holder, if you've configured your website, domain, etc. correctly it's a matter of waiting. New sites with little or no backlinks can take time get get discovered/crawled/indexed and ranked.There's some basic SEO pointers on Google's Webmaster Tools section, and I would recommend registering your site with Google Webmaster Tools to help identify any potential issues.
