Credibility of Information on
Web Sites
Information aggregated by
Jane Mitchinson-Schwartz

2. AUTHORITY

Questions to ask:
• Who is providing the information?
• Is there personal contact information?
• What is the expertise of the author?
• Does the email domain match with the
internet domain?
• Has the site been verified by a reputable
authority certification company?

3. Security Certificate Check
For sites containing secure information such as mail servers, e-retail,
Banks, and charities, type an “s” after “http” to enable a check of the
security certificate.

4. Verisign and Thawte are two of the most widely used
certificate authorities

5. AUTHORITY
Clues to look for
 Registered site (whois.net or allwhois.net)
 411 and Mapquest on name and address
 use search engines to get links or other sites
 Email or postal site that can be verified
 Read author bios or “about us” links
 Check professional directories
 check certificate of authority

6. ACCURACY
error free and reliable information
Questions to ask:
• Does the information appear to contain a
minimum amount of bias?
• Is the information that has been selected
designed to sway the reader?
• Is there any advertising on this site? What
kind?
• Who else uses or links to this site?

7. ACCURACY
Clues to look for
 Writing that has been thoroughly checked is more likely to be written
by someone who has fact-checked their information as well.
 More than one person fact-checking is better than one.
 Check for a bibliography (paper trail) Check information against
other sources.

8. Accuracy
Questions to ask:
• Is the information free from grammatical,
spelling, and typographical errors?
• Is there a person in a higher-up position
such as an Editor who has checked the
work before it has been published to the
Internet?
• Can you cross-check the information with
other sources?

9. OBJECTIVITY

Clues to look for:
 Check whether you can detect emotion in the information or the way
it is presented. (bias)
 What is present in the article and what is missing?
 Advertising may cause a conflict of interest or it may boost
credibility.
 Do a check to see who has put this site in their own links.
www.google.com or www.yahoo.com
Type in the search window: Link (space) all or part of url

10. CURRENCY
how recent the information is and its usefulness to the present
Questions to ask:
• Is the page dated?
• When was the page last updated?
• How current are the links?

11. CURRENCY
Clues to look for
 Check at top of article or bottom of page. (display source code to
detect)
 Check for a revision date.
 Links that lead to expired pages mean the site hasn’t been updated
or checked on regularly.
