If you can find pages cached by Google using the site search [site:your.site] (for example site:google.com), then you are not banned. If you can not find any web pages from your site cached by Google, it does not mean you are necessarily banned by Google.
Its not authentic I think.. It shows almost all urls banned in Google. Here is what is Test: For testing I use Google.com and result is "www.google.com currently has no pages indexed by Google.com, therefore www.google.com is BANNED from Google or is a new website that has yet to be indexed"
Yes absolutely at this case you can check the domain age. If its an old site and you couldn't find any information by site: means probably the site is banned.
If you don't see your website anymore even after typing out its exact domain in a search result, that is a big blue its been banned, you may be able to find the cache via the time machine
becareful guys i tried both is banned.com and bannedcheck i used a domain that i know is banned and one thats not. They both came up clean. This would be a great tool if it would work right. I really need a tool like this.
you may use this to check http://www.iwebtool.com/google_banned once you get banned you will in big trouble. Please stay out from banned, we can't run away from Google Eyes.
you can know that by this way write on the google search engine www.[domain].com if your site appears in the top of results that main no penalising for your site but if your site doedn't appear on the top of search results that's main google punished your site
Install gogole toolbar and start surfing the sites and may be it will notify you when you come across a site that is banned , may be there are other ways too.
