Cite web pages in text as you would any other source, using the author and date if known. If the author is not known, use the title and the date as the in-text citation (for long titles just use the first few words). Your in-text citation should lead your reader to the corresponding entry in the reference list. For sources with no date use n.d. (for no date) in place of the year: (Smith, n.d.). Below are examples of using in-text citation with web pages.
