Authority: Who is the author of the webite and what are the credentials of that person or entity? The author may be an individual or an organization.
Timeliness: How current is the information? Can you tell when it has last been undated?
Scope: How deep is the website? Is it within your range of comprehension? Is it too simple? Is it too technical?
