The CRAAP Test is an evaluation method that was designed by librarian Sarah Blakeslee at the Meriam Library California State Universiy, Chico. CRAAP stands for Currency, Relevance, Authority, Accuracy and Purpose. This provides you with a method and list of questions to evaluate the nature and value of the information that you find.
The timeliness of the information:
When was the information published or posted?
Has the information been revised or updated?
Does your topic require current information, or will older sources work as well?
Are the links functional?
The importance of the information for your needs:
Does the information relate to your topic or answer your question?
Who is the intended audience?
Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)?
Have you looked at a variety of sources before determining this is one you will use?
Would you be comfortable citing this source in your research paper?
The source of the information:
Who is the author/publisher/source/sponsor?
What are the author's credentials or organizational affiliations?
Is the author qualified to write on the topic?

.ac.uk = Academic institutions in the UK
.com = Commercial sites
.edu = Educational institutions
.gov = Government
.nhs.uk = Health information services in the UK
