Evaluating Internet-Based Information: How to Evaluate: the CRAAP Test

Is It Craap?


If relevant, when was the information gathered?
When was it posted? When was it last revised?
Are links functional and up-to-date?
Is there evidence of newly added information or links?


What is the depth and breadth of the information presented?
Is the information unique? Is it available elsewhere, in print or electronic format?
Could you find the same or better information in another source (for example, a general encyclopedia)?
Who is the intended audience? Is this easily determined?
Does the site provide the information you need?
Your overall assessment is important. Would you be comfortable using this source for a research paper?


 Who is the author/creator/sponsor?
Are author's credentials listed?
Is the author a teacher or student of the topic?
Does the author have a reputation? Is there contact information, such as an e-mail address? Has the author published works in traditional formats? Is the author affiliated with an organization?
Does this organization appear to support or sponsor the page?
What does the domain name/URL reveal about the source of the information, if anything?

Example: .com .edu .gov .org .net


 Where does the information come from?
Are the original sources of information listed?
Can you verify any of the information in independent sources or from your own knowledge?
Has the information been reviewed or refereed? Does the language or tone seem biased?
Are there spelling, grammar, or other typos?


Are possible biases clearly stated?
Is advertising content vs. informational content easily distinguishable? Are editorials clearly labeled?
Is the purpose of the page stated?
Is the purpose to: inform? teach? entertain? enlighten? sell? persuade?
What does the domain name/URL reveal about the source of the information, if anything?
