Evaluating Web Sites
Web sites usually don't undergo the same editing or reviewing processes as books and journals because Web publishers don't have to obtain an editor's approval.
Use the following criteria to determine if the Web site you have located can be rated AAA:

Authority, Accuracy, Audience

Authority
Criterion One: Credentials
  • Authors can be one person, several people, or a sponsoring agency
  • Authors are qualified if their credentials (educational level or occupational experience) match the subject of the site. NOTE: A student who doesn't yet have a degree or work experience in the subject area isn't a credible author.
Find out about the author by:
  • Checking the "About Us" link or similiar information on the site
  • Locating articles in library databases that he or she has written on the same subject
  • Verifying that he or she teaches in a subject area related to the Web page you are evaluating
  • Determining that the sponsoring organization is run by professionals in the same subject area
How to Locate Author and Sponsor Information on a Web Page:
The header and footer typically include:
  • name of the sponsoring institution or agency/group
  • link to a page describing the sponsor's contact information, mission, founders, and current staff and contributors (i.e., About Us)
  • name(s) of author(s)
  • date of creation/revision
  • e-mail address
  • snail mail address
  • telephone number
  • link to the author’s credentials (i.e., About the Author or About Us)
  • link to the sponsoring institution or group
Header
 
Footer

Criterion Two: Impact of Domain on Content
A domain designates a type of Web site.
  • .com = commercial
  • .edu = educational institution
  • .gov = governmental agency
  • .mil = branch of the military
  • .net = network (i.e., a private Internet service provider such as heartland.net)
  • .org = nonprofit organization
A domain is part of a Web address or domain name.
  • amazon.com = online store
  • cancer.org = American Cancer Society
  • census.gov = U.S. Census Bureau
  • maryville.heartland.net = Internet service provider located in Maryville
  • navy.mil = United States Navy
  • nwmissouri.edu = Northwest Missouri State University
The domain impacts the content of the site.
  • Commercial & network domains often promote businesses and/or products.
  • Educational domains usually support knowledge and learning.
  • Organizational domains sometimes attempt to convince a reader of a point of view
  • Governmental domains commonly include statistical, public information, tourism, or historical data.
  • Military sites may include historical data and information about the armed forces.
Criterion Three: Contact Information
  • A mailing address or phone number can be used to contact the author or sponsor
  • Contact information is typically available on the homepage of the site or the "About" or "Contact" page
Examples
 
 Positive Example: Creatine Supplementation in Athletes: Review
  • It is always best if an author provides a direct link to his/her credentials. However, if none is evident, try this method of "URL Splicing": Click in the Address: entry box and "back up the URL" one level from  http://www.rice.edu/~jenky/sports/creatine.html to http://www.rice.edu/~jenky/sports/
  • This page states that SportsMedWeb "is a non-profit, educational site designed for endurance athletes." At this page, click the Medical Tent button, then click the Who link to display a page that includes a link to the professional credentials for Dr. Mark Jenkins.
  • This site has an educational domain, which indicates that the information supports knowledge and learning.
  • The site is sponsored by Rice University. A postal address and phone number are provided on the university's main page located at http://riceinfo.rice.edu.
 Negative Authority Example: Absorb-Creatine.Com
  • No personal author information is available.
  • This is a commercial site offering Creatine for sale. Information may be biased to promote the use of Creatine.
  • The "General Information" link in the footer provides address and contact information for the sponsor.
Accuracy
Criterion One: Unfair Bias
Determine if the information provides only one viewpoint. That information may be unfairly biased if:
  • An opinion, cause, or social agenda is advocated without providing documented facts.
  • Advertisements are not distinctly separated from the content.
  • The sponsor sells a product related to the content.
Sponsoring Organizations
Information sponsored by groups or commercial businesses is sometimes biased, lacking objectivity. For example:
  • Organizations with a political position sometimes have Web pages supporting their viewpoints. EXAMPLE: Bush's Flawed Energy Plan. The mission of this organization is described on the Inside Sierra Club page.
  • Businesses often add information to their Web pages that encourage readers to buy a product or service they sell. EXAMPLE: How To Buy Strength Building Equipment.
  • If a sponsoring organization is recognized as an authority in a field or business, that recognition lends credibility to the information they publish on the Web. EXAMPLE: CNN.com.
Criterion Two: Verified Content
Content can be verified as follows:
  • Look for a works cited, bibliography, or references list

    A Works Cited or References List (often called a bibliography) is a list of sources, just like you would see in a research paper for a class. Entries in a Works Cited list refer to specific points of web page content. Links to "related" or "recommended" web pages do not qualify as a substitute for establishing accuracy with a Works Cited list.
  • Locate other objective, credible sources with similar information:
    Use databases available on Search for Articles to find magazine, newspaper, or journal articles. Use Academic Search for general topics.
Example:
YAHOO! SEARCH to Academic Search ASAP to LexisNexis Academic
The image below shows a search created in "YAHOO! SEARCH" to find information about preventing recurrences of breast cancer:

One of the search results displayed is a Web page entitled Breast Cancer Prevention, a resource from the National Cancer Institute. This page details specific treatments which decrease the chances of breast cancer recurrences. The information on the page can be verified by searching for articles about preventing breast cancer recurrences in the Academic OneFile periodical database as shown below:

OneFile Search Screen

The search entered in Academic OneFile database is identical to the one used in "YAHOO! SEARCH." One of the search results displayed is an article entitled "A New Drug Regimen Packs Powerful One-Two Punch." This article discusses two of the breast cancer prevention treatments mentioned on Web page at the National Cancer Institute site.

OneFile Article Citation

Another article discusses a treatment for breast cancer prevention that might verify information found the Web page:

This final article discusses some of the same drug treatment options described on the Web page entitled Breast Cancer Prevention and therefore verifies the information on the Web page.

Criterion Three: Appropriate Date
The page created/last updated statement should indicate that content is current and appropriately up-to-date:
  • Medical or computer software information that is several years old may be suspect.
  • Information about classical Greek theater that is five years old may be very accurate.
Examples
 Positive Accuracy Example: The Impact of Presumed Consent Legislation on Cadaveric Organ Donation
  • The information on this page is not biased. It is documented by facts and endnotes.
  • No advertisements appear on the page and the sponsor is not attempting to sell a product.
  • The author has no apparent agenda and is not attempting to convince the reader of a point of view.
  • The date of the paper is fairly current, June 2004.
 Negative Accuracy Example: Death Penalty Facts
  • Bias is evident for several reasons:
    • The sponsor clearly states it is dedicated to the abolition of the death penalty and there is no attempt to separate the objectives of the sponsoring organization from the content.
    • All of the "facts" provided support the sponsor's mission.
    • Many of the arguments present emotional appeals, rather than intellectual appeals aimed at an objective assessment of the issues.
  • Sources of information are mentioned but no references are provided.
  • Many of the facts presented may not be the most current information available. For instance, the Thorsten Sellin studies mentioned were conducted in 1962, 1967, and 1980 respectively.
Audience
Criterion One: Relevancy
Locating information that mentions a topic doesn't guarantee that the information is relevant or supportive of the specific research purpose.

Examples
Positive Purpose Example: Tips for Travelers to Mexico
  • This Department of State "Tips for Travelers to Mexico" provides extensive information about how to travel safely in the country of Mexico, including shopping information, what you bring into the country, and how to obtain medical assistance.
Negative Purpose Example: Avant Rent a Car: Travel Tips
  • This is an advertisement for a rental car company entitled "Travel Tips" which also includes a mention of Cancun and some other tourist destinations in Mexico. This page is chiefly concerned with promoting the use of Avant Rent a Car in Mexico with only token attention given to 'travel tips' in the comprehensive way that the Department of State site does.
Criterion Two: Type of Web Page
Determining the type of Web page helps define what audience is targeted:
  • Informational/Educational: An informational/educational Web page provides unbiased, up-to-date news, data or statistics that encourages the reader to learn and think critically about the information and draw conclusions.
  • Example: World Health News
  • Political: Political Web pages may include information, but the information is used to convince readers of the validity of a claim or point of view. Nonprofit organization or .org sites often have a political or social agenda.
    Example: MADD: Mothers Against Drunk Drivers
  • Recreational: This type of Web site entertains the user.
    Example (Use CTRL/MouseClick to open this window): Dancing with the Stars
  • Commercial: Commercial Web sites exist for the purpose of selling users products or services.
    Example: E-Bay
    Blended Examples

    An organizational site may support a point of view and also to educate the public about matters related to a particular issue.
       Example: AARP.org

    A commercial Web site may also provide unbiased information or news.
       Example: drkoop.com

     

Criterion Three: Audience Characteristics
Audience characteristics include age, gender, and interests. Answers to either of the following questions help define audience:
  • What is the common interest of those who use this Web site?
  • Does this Web site appeal to a specific age or gender group?
Examples
QVC
This is a commercial site for those interested in online shopping for a variety of products. No specific age group or gender is targeted.

ParkNet
This is an informational/educational site that provides facts about the National Park Service and properties owned by the government. Users are interested in history, outdoor recreation, or the United States' "natural or cultural heritage."

The Benefits of Curfews
This informational/educational site provides "education, training and support" for foster parents.

Lifetimetv.com: Where Women Click
This site includes aspects of both the recreational and informational/educational types. It targets a specific gender--women.

Universal Design/Home Modification: A Home for All Ages
This is an informational/educational site sponsored by the American Association for Retired Persons (AARP). Even though this site is sponsored by an organization that targets an older audience, the Universal Design principles it describes could also appeal to a younger audience with special needs or children.
