What should you look for?
According to Wikipedia, "A filter bubble is a result of a personalized search in which a website algorithm electively guesses what information a user would like to see based on information about the user (such as location, past click behavior and search history) and, as a result, users become separated from information that disagrees with their viewpoints, effectively isolating them in their own cultural or ideological bubbles." The danger of a filter bubble is that it insulates us from other viewpoints that we might learn from, creating a polarizing effect.
Get Rid of Your Search History

Turn Off Targeted Ads
You can turn off targeted advertising at the browser level. Click on the links below to turn off targeted ads for a particular browser.
You can also tell many ad networks at once that you do not want targeted ads, on the Digital Advertising Alliance Consumer Choice page.
Open Up Your Feed
Follow some news sources on social media that you might not normally follow or do not usually agree with. This will expose you to different perspectives on issues that you may not ordinarily hear or see. You might also try the Wall Street Journal's Blue Feed, Red Feed, a side-by-side look at real conversations on political topics from different perspectives.
Lean Into Your Discomfort
While reading things you don't agree with may make you uncomfortable, it will help you understand what is happening in the world in a more holistic way and--hopefully--help you understand the perspectives of others.
Stop the Spread of Fake News
Don't post or forward articles that you haven't personally fact checked. Be a good digital citizen!
Stand Up for the Truth
If your friends or family are posting less-than-credible news, challenge them to fact check their own postings or let them know that Snopes or Politifact has already debunked their information.
Push each other to think.
Most issues in the news are much more nuanced than 140 characters allows room for. Push each other to think, and give each other space to think through each other's perspectives.
Pay attention; these are some of the sites that tailor their results to your past clicking history:
