Always evaluate websites for information quality and reliability because anyone with a bit of knowledge about computers and the Internet can put information on the World Wide Web. Academic research is different from personal research because academic research requires current, correct, and well-documented information written by institutions/people who are authorities on their subjects. Sites should be unbiased UNLESS biased information is useful for a particular assignment. The World Wide Web is a place of business, and sites that want to sell products or services have a different purpose from sites that exist to educate.
This video will show you how to evaluate a website, and how to avoid websites that just "look" credible.
