Sandbox or Deindex

I search my exact site url in google toolbar and its not appearing.. does that mean it was sandboxed or deindexed.. mann i had submitted it to this free directory and i think they spam me with backlinks... anybody want to take a look for me..? pm me

Sure. PM me the link.

type site:yoursite.com in google.com if you see it its probably a google dance or sandbox. if you don't see it its Deindex

Did you purchase it as an expired domain?
If so, it probably got deindexed due to it being expired and offered no value to Google.
Try placing some unique content on there then ping it, wait for 24-48 hours for the site to be indexed.
If after a week or 2 and your site is still not indexed, you can safely assume its deindexed for good.
