site penalised

Hi everyone, I can't find any results for my site when I write: site:mysite.com Does that mean my site got a penalty? And if so, what next? By the way, the site has been indexed before and is 2.5 years old. Thanks for any comments.

I have done some PBN to my site through review copies, now all the keywords which I linked to PBN are showing N/A & lost rankings. Before that or they all showing on page 1 2 & 3 but now no keywords showing in better position. Is my site penalized due to review copies PBN? if yes then how can I...

Hi Friends, i have a doubt that whenever my site is penalized by a Google update and rankings go down, then how can we find out by which update is my site affected?means there are 3 updates Google panda,Google penguin,humming bird....so how will i know by which update is my site affected?
