下面的一段话,摘取自Site content and use of web catalogues,对于那些做SEO工作的人们也是一个警号,要小心了。

Google is willing to take action against domains that try to rank more highly by just showing scraped or other autogenerated pages that don't add any value to users. Companies, webmasters, and domain owners who consider SEO consultation should take care not to spend time on methods which will not have worthwhile long-term results. Choosing the right SEO consultant requires in-depth background research, and their reputation and past work should be important factors in your decision.
