If you are searching for a term in Google search engine and discover that according to the results presented to you some are spammy (meaning they do not relate or give very less information on what exactly you are searching for - give misleading results) Google has now given the power for users to block such sites / URL from the search results.
This is a move which draws attention of many SEOs and search marketing analysts because many believe the competitors can capitalize on such actions. Google has yet to confirm if data collected by users blocking the URLs from search results will be taken into consideration by Google's engineers but if this is done so it could be abused by any competitors and others therefore give false positives.
Some critics criticize the move by Google as say " Google lets customers do it's dirty work" to fight spam.
