The APA citation system uses the Author, Year citation style. Most citations begin with the last names of the authors or the authoring organization, followed by the year of publication. Past tense reporting verbs are generally favored by APA style. The Purdue OWL cites the rules and has many examples (The Basics). Or visit the "official" APA website for in-text citations. Direct quotes and paraphrases should also include the page number to help the reader locate the information. For phrases quoted from websites or other sources page numbers, provide readers with another way to locate the passage, such as paragraph numbers, heading names, or other identifiers.
Cite web pages in-text as you would any other source, using the author and year if known (Author, year). 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: (Jones, n.d.). Examples are found at the Purdue OWLl site ("Electronic Sources" and "Sources without Page Numbers") as well as the APA website.
