Evidence Based Content on the Internet

  • Purpose -- What is the purpose of the site/page?  Is it to inform? To educate?  To sell? To entertain?  Sometimes this information can be found in the "About" section
  • Currency --- When was the site/page last updated?  Do the links work? Sometimes this information
  • Objectivity --- Is the content objective and free of bias?  Does the site/page represent a single viewpoint?  Be aware of possible differences between .com, .org, edu, etc.
  • Accuracy -- Is the content accurate?  Can it be verified through other sources?  Are there obvious errors in grammar, spelling, facts? Are sources listed or footnotes included?
  • Appropriateness --- Is this site/page appropriate for the level of information that you are seeking?
