Evaluating Websites

Why Evaluate Web Sources?

  • Anyone with a little time, some knowledge and small amount of money can publish on the Internet.
  • No person, persons or organization reviews the content of the Internet.
  • Pages are retrieved by search engines based on the page's content, not the relevancy or quality of the page.
  • Much information on the Web is not updated regularly.

How to Evaluate Web Resources

Authority The source of the information.
Accuracy  The reliability, truthfulness and correctness of the content.
Purpose The possible bias present in the information.
