The google sand box, any guesses as to how long normally?

[illinois]

I am wondering how long other webmasters have noticed this. I notice it more on some of my domains & certain keywords.

Anyone have any experience with the sandbox on their domains. Should I expect 6 months? a year? trying to get a good idea. I think that I am still noticing this affect after 3 months easily.

Actually I don't know (for I didn't experienced it yet, hope not) but you really need to focus on high quality both in contents and link building when you entered that kind of penalization.

Most of webmasters could not predict the sandbox effect, except from Google guys. Some might even don't know it's exist in google.
