Welcome to WebmasterWorld Guest from 220.127.116.11
About one week ago the site plummeted in the rankings after enjoying a period of reasonable traffic. The only significant thing that I have done to the site recently was to gain a link from a PR7 site!
Furthermore, from what you're saying, it seems that it's possible for a site to re-enter the sandbox, meaning that the sandbox is not just for new sites? That's just great!
P.S: Sorry it's just another question and I'm not able to provide an answer to your post....
I am not implying that it is back in the sandbox and I also think that I have just been unlucky in an update. It has happened before and it will happen again.
There was a bit of discussion around this site in previous threads so I thought some of those who had participated previously were entitled to this feedback.
