One of my sites has been ranking pretty good and then it got sandbox so it wasn't ranking for that keyword at all, I kept building links to it and couple of weeks later it came back with even better position but today it dissapeared again? Any suggestion to why? Is there it chance that it will come back? I mean I"m not given up and I will keep building links to it, just would like to hear some opinions and if this has happened to you. Thank you all.
