Websites and pages present challenges when creating citations. One benefit to correctly citing these sources is that it can also help you determine the quality of the source. The harder it is to find citation information, the more likely that it is not a reputable source.
A good place to look for information about a website and/or author is on an About or Information page. You can often learn about the credentials of authors and publishers, as well as affiliations and/or sponsors that might indicate bias and/or purpose.
