I have a question regarding domains that still have page rank but aren't indexed and have been previously penalized..Is there any way possible that a website can be reindexed after being penalized? Or is impossible through google's ruthless live or die trying alogrithm
it doesn't matter your site has been penalized or not you can still get traffic not need to deindex just remove unnecessary content.
Try to fix first why your site was penalized then start to optimize your site in an ethical way and if there are bad links that need to be removed use disavow tool or contact the admin of the page to request removal of your link.
Not sure why it has been penalized, owner hasnt disclosed that information yet. Just interested in a possible domain name for the long tail keyword aspect. I'll try to find out more info. Thanks guys.
it doesnt mean that any site got penalized and he was deindexed totally various type of penalty currently google give.
The penalized domain can become good again. I once had a domain like this and created a whole new site using this domain that I purchased. You will have to make new site with all new unique content, keywords etc. And link site from good sources websites and overtime you will see your domain back in the game again. Also within your Google Webmasters account "remove" any old bad links from the site, create a new sitemap letting Google know of all the new content etc. I hope this has help.
Just keep posting GOOD and UNIQUE content and build backlinks. I am sure you will cope with the deindexed problem soon!
