Consider the source -- Can you identify the author? Know who is responsible for the content.
Focus on quality -- All Web sites are not created equal. Does the site have an editorial board? Is the information reviewed before it is posted?
Look for the evidence -- Rely on research, not opinion. Does the site identify their sources? Does it rely on testimonials?
Check for currency -- Look for a publication date. Is the information current?
Beware of bias -- What is the purpose of this site? Who provides the funding?
