Personal web pages are Worl Wide Web pages created by an individual to contain content of a personal nature. The content can be about that person or about something he or she is interested in. Personal web pages can be the entire content of a domain name belonging to the person (which would then be a personal website), or can be a page or pages that are part of a larger domain on which other pages are located - an example of one such larger site is GeoCities. Another example would be a student's website for school. Personal web pages are often used solely for informative or entertainment purposes. Defining personal web page is difficult, because many domains or combinations of web pages that are under the control of a single individual can be used by the individual for commercial purposes, ranging from just the presentation of advertising, to electronic commerce: the sale of goods, services or information; in fact eBay began as the personal web page of Pierre Omidyar.
