The Jargon File (version 4.4.7, 29 Dec 2003):

home page
 n.

    1. One's personal billboard on the World Wide Web. The term ?home page? is
    perhaps a bit misleading because home directories and physical homes in RL
     are private, but home pages are designed to be very public.

    2. By extension, a WWW repository for information and links related to a
    project or organization. Compare home box.


The Free On-line Dictionary of Computing (30 December 2018):

home page

    1. The top-level entry point web page
   relating to an individual or institution, or possibly a
   subject area.  This often has a URL consisting of just a
   hostname, e.g. http://ncsa.uiuc.edu/.  All other pages
   on a website are usually accessible by following links
   from the home page.

   2. The web page a user's web browser is configured to load
   each time it is started.  This will typically default to the
   home page (sense 1) of the organisation that produced or
   distributed the browser.
