Personal web pages are World Wide Web pages created by an individual to contain content of a personal nature rather than on behalf of a company, organization or institution. Personal web pages are primarily used for informative or entertainment purposes but can also be used for personal career marketing, social networking, or personal expression.Also often used interchangeably with the term "personal web page" are the terms; "personal web site", "personal home page", or most commonly just "home page". These terms do not usually refer to just a single "page" or HTML file, but to a collection of pages and related files under a common URL or Web address. In strictly technical terms, a site's actual home page (index page) often only contains sparse content with some interesting or catchy introductory material and serves mostly as a pointer or table of contents to the content-rich pages inside, such as résumés, family, hobbies, family genealogy, a blog, opinions, online journals and diaries or other writing, work, sound clips, movies, photos, or other interests. Many personal pages only include information of interest to friends and family of the author but some can be valuable topical web directories.
