Dear all expert Few weeks ago Google Webmaster tool send me this massage " Google has detected that some of your pages may contain hidden text or cloaking, techniques that are outside our Webmaster Guidelines. Specifically, we detected that your site may have been modified by a third party. Typically, the offending party gains access to an insecure directory that has open permissions. Many times, they will upload files or modify existing ones, which then show up as spam in our index. " When i see this message i get shocked and investigate the problem after lots of search i found some spam URL in my Website guest posts, when i found the spam URL is remove those URL and send my website back to Google Webmaster tool for review, after one week Google send me this reply. " Dear site owner or webmaster of thinkbeyondwindow dot com website We received a request from a site owner to reconsider "thinkbeyondwindow dot com website" for compliance with Google's Webmaster Guidelines. We reviewed your site and found no manual actions by the webspam team that might affect your site's ranking in Google. There's no need to file a reconsideration request for your site, because any ranking issues you may be experiencing are not related to a manual action taken by the webspam team. Of course, there may be other issues with your site that affect your site's ranking. Google's computers determine the order of our search results using a series of formulas known as algorithms. We make hundreds of changes to our search algorithms each year, and we employ more than 200 different signals when ranking pages. As our algorithms change and as the web (including your site) changes, some fluctuation in ranking can happen as we make updates to present the best results to our users. If you've experienced a change in ranking which you suspect may be more than a simple algorithm change, there are other things you may want to investigate as possible causes, such as a major change to your site's content, content management system, or server architecture. For example, a site may not rank well if your server stops serving pages to Googlebot, or if you've changed the URLs for a large portion of your site's pages. This article has a list of other potential reasons your site may not be doing well in search. If you're still unable to resolve your issue, please see our Webmaster Help Forum for support. Sincerely, Google Search Quality Team " But still Google not index my website on the same place where it is few week back before hacking message i got daily 2000 to 2500 visitors on my website but after this message i get daily 200 visitors on my website please tell me some solution how i get back my website same position on Google thanks
