- Who is the
**author**? What their credentials and are they qualified to discuss the subject? - How current is the information? On what
**date**was the website last updated? Older information may no longer be accurate. - What is their
**point of view**? What type of bias are they portraying? Every one has a bias/point of view but it's important to investigate both sides. - How
**accurate**is the information? Can what is being presented by the author(s) be verified? Are there spelling, grammar, or typographical errors? This may require comparing other sources. - Who is the
**audience?** - What
**domain**is being used? Domains that contain**'.gov'**or**'.edu'**tend to be more reliable than those with**'.com'**or**'.net.**' This is not to say**'.coms'**or**'.nets'**are always unreliable.
