Evaluating Websites

Have you ever used the CRAAP test?

If you are using a website for research you want to find GOOD and RELIABLE websites.  You want to evaluate them for credibility and appropriateness.  There are a lot of websites out there that promote misinformation, are not fact-checked, or are just opinion pieces (to note a few examples of unreliable information).  You might read and consider an opinion piece in your personal life, but for the most part it will not be used in academic work.

Not sure how to evaluate websites to find good information?  Follow the CRAAP test!

The CRAAP test asks you to evaluate sources based on three criteria:

  • Currency--The timeliness of the information (how current is it?)
  • Relevance--The importance of the information for your needs
  • Authority--The source of the information
  • Accuracy--The reliability, truthfulness, and correctness of the information
  • Purpose--the reason the information exists

To learn more about how to use the CRAAP test, such as questions to ask yourself as you encounter websites, see this handout developed by librarians at California State University--Chico.

Finding Reliable Web Resources

One way to find websites that are reliable (can be trusted to have true information) is to use Operators as well as other search tricks.  These operators allow you to tailor your search to retrieve better results.  The image below shows one of the most useful operators as well as another trick to help you search.  Other common operators can be found HERE.

In the image, there is an operator site: You can use this operator to tailor your search to particular types of sites such as educational institutions (edu), organizations (org), or government institutions (gov).  These are three most common types of sites you would find reliable information on. 

The other thing to note below is that the phrase medical terminology is written with quotes around it.  This tells Google that you only want results back that have the phrase medical terminology.  Without those quotes Google may retrieve websites that have the words medical and terminology but not as a phrase.  This allows you to find more relevant information.
