The ABCD of Website 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, 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 or other obvious mistakes?
