Evaluating Websites

The CCOW method is useful for remembering different approaches for evaluating sources. Consider this as a way of thinking more than a checklist for thinking and can be used when evaluating information and sources. 


  • What's their educational background? Do they have an advanced degree in the subject under discussion?
  • What's their occupation? Do they work in a field that qualifies them to talk about the subject?
  • Do they have any other experience that might make them a good source of information? For instance, an eyewitness to an earthquake doesn't have to be a seismologist to give good information about what it was like to experience that event.


  • Is the information supported by evidence?
  • Has the information been reviewed or refereed?
  • Can you verify any of the information in another source or from personal knowledge?
  • Does the language or tone seem biased and free of emotion?


  • What is the purpose of the information? to inform? teach? sell? entertain? persuade?
  • Do the authors/sponsors make their intentions or purpose clear?
  • Is the information fact? opinion? propaganda?
  • Does the point of view appear objective and impartial?
  • Are there political, ideological, cultural, religious, institutional, or personal biases?


  • Who are the authors writing this for?
  • Who is the author/publisher/source/sponsor?
  • Are the author's credentials or organizational affiliations given?
  • What are the author's credentials or organizational affiliations?
  • Is there contact information, such as a publisher or e-mail address?
  • Does the URL reveal anything about the author or source?
