A few weeks ago, Google introduced a Chrome plugin that allowed you to block sites you didn’t want to see in your results pages. Now, the search giant is taking this concept a step further and allows anybody to block sites right from the search results page. There is a slight twist to this, though. The link to the block feature will only appear after you have visited a site. So if you want to block a site that you deem to be offensive or of low quality, you first have to visit it before you can block it.
