Hello, I have a very visited subdomain which was 2nd in google search for a keyword. about 2 months ago i noticed the subdomain went down to page 4-5 for the same keyword (and other keywords) and i didn`t made any change to it . Today the subdomain (although it has a 4 pagerank) is no more in google searches for that nieche ... and even when i search subdomain.domain.com, google doesn`t return any results. I lost about 12k uniques/day because of that ... Can anyone tell me what i did wrong ??? am i banned?? if i`m banned what can i do ? if you want me to tell you the link too look over, i`ll PM , i don`t want anyone here to think this is an underconver spam i underline that i have other subdomains that are absolutelly ok.(at least until this moment) thank you !
