The Internet is vast with resources of varying worth. This page was
created to suggest criteria to consider when consulting Internet resources
about health topics. Evaluation criteria can be divided into two main
areas: Content and Design.
Is the information valid and supported by evidence? Are omissions
noted? Is the author's point of view objective and unbiased?
Who is responsible for the information? What are the author's
creditials? Is a mechanism in place for you to contact the author?
When was the site created? Was it updated recently?
Does it state that the content is not medical advice?
||Is this source too elementary, too technical, too advanced, or just right?
||Are there links that point to additional, valuable resources with minimum effort?
Purpose of the site
||Is the purpose of the site clearly stated? Does the site match its
purpose? Is the site intended to educate or sell?
||Does the site offer unique information?
Ease of use
||Is the site designed to make it easy to navigate? Are menus arranged
logically? Do function buttons stand out?
||Are colors and graphics used to make the site functional and attractive?
