My site had about 9,000 results when searched for before and suddenly everything is gone and I'm completely out of Google index. A few days later Google emailed me saying I have been removed for 30 days because I have concealed text on one of my pages. They listed the text as: Quote:what's the page in question?by the looks of that quote, it looks like you may have been hacked and don't even know it.I don't want to post the site publicly so I'll pm it. I use Cutenews and I'm thinking maybe something happened there. I'm going to try to reupload the Cutenews from the original.I looked at as many pages as possible in both languages. I could see no sign whatsoever of hidden text. Same as you. Perhaps you are correct about the cutenews.How did Google get your email address to email you? Did you email them first?I think they must have gotten my email from my website because I didn't know how to email them. I removed my CMS and reinstalled a clean version, then used the Google webmasters tools thing to submit a reinclusion request. Hackers are mean.Click on your website anywhere.Then press CTRL + AAnd if there is some hidden text then you will know.Moreover this things happen when the color is too much blended in.Google have adopted the policy of removing sites for a short period and letitng webmasters know in case exactly this type of thing happens as to not ban or penalise the site, rather let you know and give you enough time to fix it.Your site will return to normal in the serps as long as you have cleaned the site/pages.
