or simply say..if your website is not being visible on your domain on Google then think your site is banned in Google....
This search term is effective IF your site is already indexed before. But if its just a new site, you can try search it in SE search bar using the website URL itself.
Great! Now I've got another thing to worry about when I see Google dropping my pages! Well as long as they don't drop all of them I guess I am still ok!
