Splash Page - page used with multiple things changing
on it that is geared to impress the end user. A splash page usually has
little readable content on it to be indexed by search engines.
Using a splash page may be a good idea if you are a web designer and
want to show off for future potential clients. I can think of few good
actual applications of a splash page for the home page though. Generally
splash pages are used to show off ego. The back button is one of the most
frequently used items on web browsers. Splash pages are part of the reason
why that is true.
