Have you ever run into information on the web that made you think twice? Anyone can create and post content online without any reviews for accuracy or objectivity. So knowing how to quickly and effectively figure out if a website is trustworthy is a critical skill in life and at school. |
How to evaluate websites: Evaluating the source title slide |
If you encounter an unknown website, it can be difficult to know if the information is trustworthy. The most efficient way to evaluate a web source is by leaving the site and discovering what other sites are saying about it. This is the process that professional fact checkers follow. Like fact checkers, we want to start by going outside the website to evaluate the source, asking questions like who published it? and why? Then if the source is credible, we can move on to evaluating the content of the website, the what, when and how, to decide if it makes sense to use the information in our work. |

When we talk about evaluating a source, what are we looking for? First, Who? Who was responsible for publishing and maintaining the site? It could be a scholarly organization, a professor, a government agency, news outlet, corporation, independent blogger. Also, what are their credentials or expertise? Look for the background of the author or the source of funding for the site. Next, consider why the information was published or posted. Is the purpose to present research, to give an opinion, or to persuade someone to a point of view? Is there a call to action, for example, to donate money, vote for something, buy a product? These questions can help you identify potential bias or unreliability in web sources. |
WHO
- Who is responsible for the site?
- Who created the content?
WHY
- Why was the information published?

For example, let's say I'm working on a physics project and found this visual explanation of Faraday's law. But I'm not familiar with the website called HyperPhysics, and I'm not sure if I could trust it. I would start by figuring out who is providing this content. |

The site homepage tells me the copyright is held by someone called C.R. Nave, and the site is hosted by Georgia State University. |

So I can search online for C.R. Nave on the web to see what else I can learn about them. My search results include a reference for C.R. Nave and the Department of Physics and Astronomy at Georgia State, HyperPhysics, which is the website we're evaluating, a Wikipedia page about the HyperPhysics website, a book review mentioning Physics for the Health Sciences, a textbook coauthored by C.R. Nave. |

The review is published in the American Journal of Physics, which I recognize as a reputable, professional journal. |

Let's check out the Wikipedia page to see what else we can learn. The Wikipedia page describes it as an educational website, which tells us something about why it was created. That also confirms that the site is hosted by Georgia State University and Dr. Rod Nave, the author, is a faculty member there. That said, since Wikipedia is crowdsourced, it's always a good idea to check the references at the bottom of the Wikipedia page to make sure the information is trustworthy. We can scan the list for sources we already know and trust, like IEEE, which is a professional engineering association, the New York Times and a public television website. We can also follow any of these links. |

For example, the fourth source on this list is a faculty listing for Georgia State University confirming Nave's affiliation. |
Georgia State University Physics and Astronomy Faculty List including Carl Rod Nave’s contact information. Nave is listed under Emeritus Faculty as “author of Hyperphysics”. |
In summary, by searching outside of the HyperPhysics website for information about the WHO and the WHY, we were quickly able to determine that this source was credible. Next, we would move on to evaluating the content, the what, the when and the how. |

However, not all resources are as clear as this example. So what should you look for? First, pay attention to the language that outside sources used to describe your website and its authors. For example, your source might be described as a trusted news provider, a leading manufacturer, a respected professor or researcher, or a well-established professional association. In short, if your source is consistently described by other sources as having a strong reputation, it is likely to be reliable. There are also some red flags that could signal that your source is biased or not credible. For example, inconsistent descriptions of your source or a controversy around it, a financial or political interest in the information being provided. For example, if it comes from a lobbying organization or marketing agency, or if it's not clear what person or group is responsible for the source. If you discover any of these red flags, you should probably look for another, more reliable source. |

You may be thinking: How do I know which of the outside sources are trustworthy? How do I know if IEEE or 60 Minutes are credible? As you learn more about your field, you will get to know which authors, organizations and sources are trustworthy. In the meantime, you may need to do a little additional research. Check for references, especially on Wikipedia pages. To find them, scroll to the bottom of the page, as we did in the HyperPhysics example. Scan the results for sources you recognize. That strategy works well for web search results, too. Don't rely on the first few results. You can scan more of the list to see if there are sources or other names you recognize. You can also ask your professor or your subject librarian for help. |
