I've come across these types of pages too, in error, while typing too quickly and transversing letters (or putting too many ooo's in Google http://www.goooogle.com/). Most of these webpages have banners across the top that read "Your Home on the Net", "What You Need, When You Need It" or "Your Information Portal" & feature some generic looking guy or gal engaging in daily life.
Here's my question: is there a WORD for these types of pages? I've been calling them filler pages, for convenience's sake. But does a real, descriptive word exist?
