Can you identify an institution or organization? Look at the URL (web address) for information: is the page hosted by an educational institution or government department? Is it a commercial site, or a personal web page? Has the article been dated? When has it last updated? Does it cover recent news? Can you check the information? Sites that quote statistics should have a bibliography. What kind of references have been used? Are all aspects of the subject covered?

Is the information biased, controversial or misleading? Extreme or emotional language is a warning sign.
