I bought a genuine 3 year old PR8 domain and put up an autoblog with WPRobot & WPUnique and within a week, I started getting 1500 uniques per day. Then on a day I added my Adsense on each page and next day - BAM - my PR8 website is fully de-indexed by Google. Can anyone plz help me get this PR8 get re-indexed ?
You can try to look inside WebmasterTools. Sometimes you get notifications here, for example if there were any malware or malicious script. I'd recommend to check there and see if there is any news about why it was de-indexed.
Could be one of a number of reasons. Without seeing the site, my first guess is because it is an AutoBlog (too much duplicate and/or low quality). Why waste a PR8 on an AutoBlog?
I discovered a Technique that might help to recover your site. On your robots.txt put Disallow /. This will tell the robots to deindex your page. Wait until de indexed about two weeks or more. Re set the to robots.txt to allow, and your site might be reindexed properly. If that does not work: Buy a new domain, add new content, get some backlinks. And when it gets some traffic, create a 301 redirect from your old blog to you new one and it will recover its rankings.
Are you sure that, it was a Real PR?? not a Fake PR?? The seller might have made you fool. If its not late, you may refund your money if possible. You should have asked for the Valid PR first. For more: http://forums.digitalpoint.com/showthread.php?t=2329351
Google panda is keep on de-index those duplicate content, if you want to get r3e-index, you need to remove those duplicate content and input fresh content
You should know adsense doesnt allow autoblogs be carefull with thinbs such as wprobot you might get your account closed FYI
Life player i agreed with you that Google Panda still finding autoblogs and others auto content optimization websites for de-indexed and i have noticed from last panda update on september-11 google rank ecommerce as well faster than content website.
Here's your first problem - wp robot. You filled your blog with dupe content. Then there's you second problem, the one that got you banned. WPUnique. If you really think you can 'fool' a giant software company like Google by changing a few characters in your text for HTML control codes, you need your head examined. If you don't get it, check this out - uniquify your content, free. And p*ss off the search engines! we give that away free as it's so worthless. Tools like wpunique mean a ban, instantly. Using tools like 'thebestspinner' in auto mode also mean a ban, because the Panda can now spot the grammar and syntax errors tools like that introduce. The good news is that you CAN now make wordpress posts unique and still readable (i.e. they will pass Google) - you just need to use the ContentBoss wordpress plugin.
