Guidelines for Evaluating Web Sites. ERIC Digest.
With increased access to the Internet, Web sites are becoming popular
educational resources. Not every site makes a good resource, however, so how
does one decide whether a site is worth using? The following checklist, compiled
from several sources, is a summary of criteria for evaluating Web sites; the
more criteria a site meets, the more likely it is to be a valuable resource:
* Verify that the Web site's
important capabilities, such as graphics or animations critical to the subject
matter, can be utilized with the technology you have available. Some sites
require more advanced browsers.
* The page should be stable, that is, consistently available.
* All the links and special features such as audios must be functioning; it
is disconcerting if "Error" messages appear.
* If there is a fee for using the site, the site should provide a secure way
to send payment.
* A site's purpose should be clear, and its content
should reflect that purpose, be it to entertain, educate, or sell.
* Advertising should not overshadow the content.
* A site's content should be comprehensible,
appropriate, and of value to the intended audience. Awards won by a site may
suggest quality but may also be little more than advertising banners for the
* There should be enough information to make visiting the site worthwhile.
Information on how often the site is visited may indicate its usefulness.
* Although there may be variations in how information is ordered, the
organization should generally be logical.
* Sites that promote social biases (e.g., gender, racial, or religious
biases) should be rejected or critically reviewed.
* If there are large amounts of information on the site, there should at
least be a site map or outline of topics that allows users to find topics and
move among them easily. A search function for locating information within the
site would also be useful.
* The information should be current, accurate, and regularly updated. A "last
updated" notification is a useful feature.
* Copyright information is useful if you anticipate copying a substantial
amount of the content for dissemination.
* Links to more information on the topic should be provided.
* Graphics should be relevant and appropriate to the content.
* The name of the individual or
group creating the site should be clearly stated.
* The Web site author or manager should provide contact information for users
to make comments or ask questions.
* Where applicable, reference sources for information cited should be
* Sites that clearly violate copyright statutes or other laws should not be
linked, listed, or recommended.
* Language used in messages and instructions
should be clear, concise and easy to understand.
* The skills required to use the site's features should be appropriate for
its intended audience.
* Navigation within the site should be easily carried out. Required
"plug-ins" or other helper applications should be clearly identified, and
navigational buttons should be of a consistent shape and location. Links should
be descriptive of the content, and link text items should sound like invitations
to content, not "click me/this/here."
* If a search function is available, instructions for conducting searches
should be provided.
* There should be consistency in the use of features such as headers,
backgrounds, fonts, and colors, particularly when they act as thematic pointers
(e.g., sub-headings use a smaller font than major headings).
* A text-only option is useful for sites with a lot of graphics; otherwise,
download time may be too lengthy. Generally, wait time should not exceed 15-20
* If necessary, look for features catering to the needs of special
populations such as visually impaired and hearing-impaired users. For example,
images conveying important messages such as page titles or links should come
with alternative text (text that is displayed when the cursor moves over the
image), so that visually impaired users using screen readers will hear the
relevant text when the cursor is over the image. Audio clips that convey
important content (such as lyrics or announcements) must have optional links to
readable text for hearing-impaired users.
* The site design should be appropriately
appealing to its intended audience.
* The text should be easy to read, and not cluttered with distracting
graphics, fonts, and backgrounds. There should be appropriate "white space,"
that is, space that is not occupied by text or graphics.
* The design elements and features on the site, such as searchable databases,
animations, graphics, sound files, and transitional pages, should be labeled and
* The site should make use of conventional rather than cute but confusing
features. For example, hypertext should be in blue text rather than buttons
without accompanying text.
* Links should not lead to so many levels that it is difficult for users to
get back to the page they started from.
* Sometimes the same site looks different on different browsers. Colors,
graphics, and text may change. If you are looking at a Web site on your own
computer, check to see how it will appear on the computers that other users,
such as students, will be using.
* The color scheme should not be too gaudy and hurtful to the eye. Most
experts recommend that a site contain no more than four colors, with a limit of
seven throughout the site. Some suggest that a site contain both warm colors
(e.g., red, orange, yellow) and cool colors (purple, blue, green). The most
important consideration, however, is whether the colors distract from the main
* The colors may also need to be appropriate for color-deficient users, who
tend to see everything in shades of green and grey, so check to see whether
important messages are conveyed by differences or changes in color.
* A site has better readability if dark text appears on a light background,
or vice versa. If pages need to be printed, pages using light backgrounds and
dark text will produce better hard copies than pages with dark backgrounds and
* Large images should be presented in thumbnail versions, with links to the
ONLINE SOURCES OF EVALUATION CRITERIA
* Two useful online
sources of criteria for evaluating Web sites for children are located at:
* Selection Criteria
* Kids Site Selection Guidelines
* A comprehensive list of criteria for evaluating Web resources in general is
provided by Ann Symons in "Sizing Up Sites: How to Judge What You Find on the
Web" in the School Library Journal, v43 n4 p22-25, April 1997, currently
available on the online Expanded Academic Full-text Elite database, and as ERIC
Database document number EJ 543 163.
* A Web-based public service offered by the Center for Applied Special
Technology (CAST), called Bobby, analyzes Web pages for their accessibility to
people with disabilities as well as their compatibility with various browsers.
