Case:- I had 3 websites and around 3 years back these sites got de-indexed or got in sandbox. Now i want to understand -- a) How can i bring back the sites (indexing mode) or is there anyway i can check that they are still penalized? I checked and found these sites are not online or being owned by anyone. The Content rite now is flushed and its just like brand new. b) How can i find, that what were the reasons for getting these sites de-indexed. I had submitted my xml to google webmasters... Waiting for useful information to bring myself back in online business...
