Website Structure?

[Princeton]

you should be thinking about and targeting your visitors needs and wants

the more you know about your target audience the easier it will be to "build" for them

What do they like?
What type of connections do they have? Broadband, Dial-up, Mobile, etc
How old are they?
Male or Female?
etc

once you do that, you need to consider your goals and needs (eg. increase revenue, increase membership, SEO, etc)

with that said, avoid music and flash - they should only be used to showcase ..
