could you please share your site address to have a look?
Sites can be deindexed for various reasons!

 

Was it indexed before? If yes, then there could be many issues which caused the de-indexing. Broken sitemap, duplicate content are some of them.

 

You could try signing up with Google Webmaster Tools (http://www.google.com/webmasters/).

Add your website there with a link to a xml sitemap of your website and Google will index your site regularly. Mine is indexed every day.

 

don't mess too much with your site. check again about 3 days or 2 weeks. if you did nothing wrong, don't worry.. he is comming back!

 

I think you need to relax and calm down, it will probably come back within days.

 

check robots.txt file.....I think it has some problem

 

Your site had not been indexed in google.
Make sure to check GWCP...........

 

You may have done something banned by Google.
