Here are some techniques that can help:
I. Look at the URL (web address).
The domain name (lib.jjay.cuny.edu in the above example) offers some clues as to the origins of the site. It is usually an abbreviated form of the name of the site sponsor. Is it a name you know?
The various suffixes tell you the top-level domain of the site, or what type of site it is. For example:
This can help you determine the purpose of the site. Is it primarily to persuade, to inform, to advertise? Does it suit your purpose?

III. Who is responsible? Can you find the name of an individual or organization responsible for the content of the site other than a webmaster?

What can you find out about the author? Use a search engine to check
the name or use one of the Library’s databases to see if the author
has published in journals or magazines. Use reference books such as the Encyclopedia
of Associations (Ref. AS 22 .E5) or Who’s Who in America
(Ref. E 176 .W642).
V. Who is the intended audience? Look for a statement of purpose or some other clue to see who the web site is aimed at. Is it meant for children, professionals, students, the general public, etc.? Choose accordingly.
