My website has been banned! I cannot find it anywhere in Google or even in AltaVista for that matter. Now I just cannot find my site anywhere! What should I do?
It depends. Did you use any blackhat techniques etc? If that is the case your site is gone for atleast 6 - 8 months! If you just upgraded your content then it may seem to have lost PR and you're just not seeing it. Checked Google Webmasters?
Check out this link. You can do something called a "Reconsideration". http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=35843
you can make new quality content with white hat techniques build some good back links, and do Reconsideration for your site.
