The ABCD of Web Evaluation: What to look for 

• Authority - Who is the author? What are the author's credentials?  Does the author have expertise in the area? Is the author associated with a reputable organization?
• Bias - Is the information balanced? Is it more opinion than fact? Is the page a presentation of facts or designed to sway opinion? Is a product, service, donate button, or idea being sold?
• Currency - When was the page last updated? Are any links dead? Is the information consistent with your knowledge in the subject?
• Documentation - Is information documented with references? Are the facts given supported with evidence? If statistics are provided, what is the source? Is the page free of spelling mistakes
