Google on Thursday announced the availability of a new feature that allows users to block specific domains from appearing in their search results. Google has taken several measures lately in an effort to improve the quality of its search results, which can often become devalued by “content farms” and other sites that make it their business to game Google by churning out low-quality search friendly content. Beyond changes that Google has made to its algorithms, users can now take it upon themselves to weed out the junk that Google misses. When users click on a search result and then return to Google, they will now see an option to block domain that was clicked. The result is a customized search experience that will continue to improve over time as users block more domains. Google is currently in the process of rolling out the new feature, which should be available to all users soon.
