https://www.google.com/search?q=site%3Amysitename.com&rct=j For example: The website is lovechix.com (its not owned by me, just saw it with the same problem like me) The result : https://www.google.com/search?q=site%3Amysitename.com&rct=j#q=site:lovechix.com All results are just removed by Google. Google Say That Reasons : It is possible that this site is not performing particularly well in the search results on Google, because it seems that violate our guidelines Webmaster. Cloaking and / or sneaky redirects It seems that some pages on this site be cloaking (showing people content that differs from to search engines) or redirecting users to a different page than I saw from Google. They recommend me to use this help page : https://support.google.com/webmasters/answer/2604723?ctx=MAC but i cant understand hat to do and to send to google to review again my website.... Anybody know about this problem and can provide me some help? Thanks a lot!
There are an infinite number of possible reasons. You should start by looking though webmaster tools to see what it says about your crawl stats. I had something similar happen with a client of ours for a silly reason. We told WMT to prefer non-www, then recently we added a site redirect from non-w to www. The resulting conflict caused Google to remove the whole site from their cache.
That means you have tried to fool Google to get higher rankings, so Google have removed all your pages from SERP. The first thing you should do is remove the redirection code from your site that is showing different content/redirection to Google. The next step is Send a reconsideration request to Google with all proofs that you have deleted the redirection code from your site with an assurance that this will never happen again.
Unless you have a manual penguin penalty, don't do a disavow!!!! Regarding the advice above, what he says is entirely possible. Webmaster Tools will tell you if something's up.
