- Author's qualifications for writing on a subject are often absent.
- Lack of Objectivity
- There are many types of Web documents (news, marketing, government, educational, personal, etc.) and they all look largely alike, but there are varying standards for objectivity.
- Many Web documents blend fact, opinion, entertainment and advertising into a seamless whole.
- Currency
- Dates are not always included on Web documents.
- When included, dates may be ambiguous (e.g., date of creation vs. date of last update).
