One of the most important steps in improving your site's ranking in Google search results is to ensure that it contains plenty of rich information that includes relevant keywords, used appropriately, that indicate the subject matter of your content.
However, some webmasters attempt to improve their pages’ ranking and attract visitors by creating pages with many words but little or no authentic content. Google will take action against domains that try to rank more highly by just showing scraped or other cookie-cutter pages that don't add substantial value to users.
If your site has been removed from our search results, review our Webmaster Guidelines (including the above links) for more information. Once you've made your changes and are confident that your site no longer violates our guidelines, submit your site for reconsideration.
