If you're sick of seeing content farms and other spammy links showing up in your Google search results, you can manually block any site through your Google Account preferences. Here's how.
Google added a new feature to their search results page that let you block any search result after viewing the page. However, having to navigate to the page first was kind of annoying, and lately, I've been finding that this "Block _____.com" link doesn't even show up most of the time -- meaning I kept getting crappy search results with no way to filter them.
Lifehacker reader Java-Princess, however, discovered that Google has another method for blocking sites. All you need to do is head to this page and type in a URL in the text box at the bottom. You can also unblock sites you've previously blocked, which is great if you ever blocked a site accidentally, or if a specific site decides to become more useful in the future. Hit the link to check out the feature, and let us know what useless sites you've blocked in the comments below.
