Don't believe everything you read. Ask some critical questions about every website:
Who
- Is the author easily identified? - check for an "About us" link
- Why should I trust what they say? - check author's reputation in Google
- Are they credible? - look for relevant educational qualifications and professional experience
What
- What type of information is provided? - personal opinions? research findings?
- Does the author cite sources so that you can verify the info? - confirm in other sources
- Are the sources scholarly? - see features of scholarly journals
Why
- Is the author trying to sell something? - watch especially with .com websites
- Does the author or organization have a political or ideological bias, and only present one point of view? - look them up on Google
When
- How current is the information? - look for sites that are updated regularly; some areas can change rapidly, e.g. medicine, law
How
- Is the site logically arranged? - avoid sites with many dead links
- Does the site look professional? - not full of misspellings
