  • What can the URL tell you? (domain, publisher)
  • Answer these questions- scan perimeter of page (about us, philosophy, background, biography, currency, credentials, etc.)
  • Look for indicators of quality information (links, documentation/footnotes, credibility)
  • What do others say? (linking pages, listed in a reputable directory, what others say about the author)
  • Does it all add up? (why was page put on web, purpose, is this as reliable as resource as you would find in a library?)

6 Questions (UW-Madison Libraries) 

  • Who - created the page/site? Look for an "About us"? What are author's/organization's qualifications?
  • What - is page/site about? Does it have info you need?
  • Where - is the info coming from? Check the URL/domain, look up domain owner
  • Why - is the site on the web? How does it affect the info? Look for purpose, mission, and advertising. Is the site being persuasive?
  • When - was the site created/updated? Is the date important for the timeliness of the content?
  • How - accurate or credible is the page? How would I cite it? Are there spelling or grammar errors on page? Can I verify the info from another source?
