WTF...More than 20 doorway sites banned by big G, is losing more than 20K very targeted Big G traffic daily and some money... I checked the Webmaster Forum By Big G and found many people got their sites banned recently. I am thinking that Big G is changing their algorithm to ban websites with a lot of duplicate contents (Auto blogs and other scrapper sites) more easily. Blackhat Big G is getting more difficult, time to think new strategies. If you have sites banned by G recently, please share your stories so we can discuss what to do next in 2011..
