Evaluating Web Pages


  • Identify the author and the author's expertise on the topic.    
  • Verify the facts, statistics, or quotes on the web page in another source.    
  • Identify the agenda of the page: are they selling something or promoting a point-of-view that benefits them?     
  • Check to see when the page was last updated. If you can't find a date, consider using a different source.  


  • Most people don't know what they are talking about.    
  • Many people will make up facts, misrepresent facts, or leave out facts in order to support their position.    
  • People will tell you anything if money or power is somehow involved.


  • Learn to think for yourself and do not rely on gathering other people's opinions posted on the internet.
