I dropped in google ranking, why ?

[chipchip]

Just checked my search / keyword for which I was on no. 4 on google until yesterday. Today I checked and my site was removed from google!


Now I'm upset since can't find out what I did wrong, read somewhere that the problem is that I have been "sandboxed" how can I get listed again, I really need to solve this it is costing me trafic

I don't think you have been sandboxed, it is very common that once you get on a high position in google then after a time you will disapear just to get listed again after a few days on a even better position.
