When using websites in your research, use the CRAAP test to evaluate the validity of the information.
CRAAP stands for:
Currency - When was the information written or published? Has it been updated? Is it out of date for your topic? Are the links functional?
Relevance - Does the information answer your research question? Who is the intended audience? Is the information at an appropriate level?
Authority - Is the author a person, company or organization? Is the author an expert on the subject? Is contact information included? Does the URL reveal anything?
Accuracy - is the information supported by evidence? Can you verify the information? Is it peer reviewed? Does the language seem unbiased? Are there spelling, grammatical or other typographical errors?
Purpose - Is the purpose to inform/teach/sell/entertain/persuade? Do the authors make their intentions clear? Is the point of view objective?
