Hello buddies,
I'm confuse about something that happened with my website "www.viciadosnosexo.com"...
For several months appeared in first page of google results with the keyword "sexo".
One day, suddenly disappeared... never understood why. I logged into google webmasters central, but didn't got any notification from google.
Do you have any clue why this happened?
And what I need to do so I can recover the position again?
Should I work in getting quality backlinks?
Is meta keywords important? What the best keywords to choose?
Any other idea?
I really appreciate your help

Thank you!
