Thanks a lot to you for share such as very very important Google Update Information. Such as information is really may very very useful for all webmasters who try to rank websites..

 

a scraper site is one that copies content from other sites aka "duplicate content"
a content farm is a site that creates low quality keyword optimized but original content aka "low quality content"

both are not very useful to the end user on Google.
