Why to Use Splash Pages ?
# Multiples sites share the same domain. Or a large site tries to communicate its most important sections directly.
# Splash page is supposed to include hints for browsing the site and explains the main sections.
# Designers use splash page trying to awake excitement for the actual content of the site.
# Sound is announced. Visitors are asked to turn on their loudspeakers to enjoy the Flash-show or Midi-experience (yes, apparently Midis are still alive).
# Splash pages are used as an additional form of advertising.
# The decision to use a splash page is design-driven and realizes some designer’s idea.
