Its so simple just follow some steps here: Determining whether or not you are in the sandbox or banned 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. If you have not been banned, but do not rank well with Google, you should look at the quality of your content and the quality of your inbound links. You should also see if you rank well for non-competitive keywords. Remember how the filter affects competitive keywords more than less competitive keywords? Well, you can use this to determine if you have been sandboxed. Finally, if you rank well in all the other major search engines, but do not show up at all in Google’s rankings, you have probably been sandboxed.
Have you placed any content on your site already? If yes and you placed the content 2 weeks ago (at least), you can check if your site banned or not going to google and use the command: site:yourdomain.com If you'll see pages of your site, so your site is alive in Google.
gilbertimlay I gave you rep. Great answer. And, anybody with signature links such as yours has surely been to the sandbox before!
Very simple: -Sandbox: listed in Google (although not high SERPs) -Banned: NOT listed in Google Do site:yoursite.com on Google, if nothing appear, you are banned. This is the acid test
