Block sites from Google result without extension

It is now possible to remove sites from your Google search result without having the need to install a Chrome extension. Late last month, Google changed its search ranking algorithm and filtered away "unwanted" search results so as to improve search result.

To use the new feature of manually removing domains, make sure you are using google.com in English. Marked domains will be saved to your Google Account.
