Determining whether or not you are in the sandbox is a relatively easy task to do. First, being placed in the sandbox is different than having your website banned.If you do a search for your domain in Google and they return zero results for your website (and you had been previously listed in Google), there is a chance that you have been banned. One of the best ways to determine if you have been banned is to look at your log files to see if Google is visiting your website. Banned websites typically do not see Google visit their websites, regardless of who is linking to them.
