Google announced its latest algorithm change will decrease the rankings for sites with a reputation for having low-quality or second-hand content. These sites are often called "content farms" or "scraper" sites, and although Google has declined to specifically name the type of site the new algorithm will be punishing. So be careful ...................!!!!!!!!!!!!!!!!!!!!!!!
