Evaluating Websites

It can be difficult to vet health information on the internet. The CRAAP Test is a list of criteria that can help you evaluate the information you find.


  • How old is the information?
  • Has the information been revised or updated?


  • Does the information answer your question?


  • What is the publisher or source?
  • What are the author's qualifications to be an expert on the topic?


  • Is the information supported by evidence?
  • Can you verify the information from another source?


  • What is the purpose of the information?
  • Is the information a fact, opinion, or propaganda?
