It's important to be careful when using websites for your research. Many websites may present only one side of an issue, or may even present false information. Consider the criteria below when looking at a website.
Author: Is the author named, or are they anonymous?
Date: Is the article or website current and up to date? Is there a date on it at all?
Authority: Does the website tell you where its information is coming from? How do you know it's factual?
Bias: Is the website's goal to inform or to persuade?
