Evaluating Websites

The CRAAP Test, developed by Molly Beestrum, is a useful tool to help you think critically to determine if a website is credible. So the next time you want to use a website in your research, ask yourself these questions:
  • How recent is the information?
  • How recently has the website been updated?
  • Is it current enough for your topic?
  • Why might the date of publication be important?


  • What kind of information is included in the resource?
  • Is content of the resource primarily opinion? Is is balanced?
  • Does the creator provide references or sources for data or quotations?


  • Who is the creator or author?
  • What are the credentials? Can you find any information about the author's background?
  • Who is the published or sponsor?
  • Are they reputable?
  • What is the publisher's interest (if any) in this information?
  • Are there advertisements on the website? If so, are they clearly marked?


  • Are the facts correct? Can you verify them with other sources?
  • Does the author provide sources?
  • Is the evidence backed up by data?

Purpose/Point of View 

  • Is this fact or opinion? Does the author list sources or cite references?
  • Is it biased? Does the author seem to be trying to push an agenda or particular side?
  • Is the creator/author trying to sell you something? If so, is it clearly stated?
