when dealing with a web site, especially a corporate web site, branding is the most important thing. therefore, the logo has to be the most visible element on the site. that means it has to be on every page, preferably in the upper lefthand corner of the page. the logo must also be large...set your screen to 640x480 resolution and make sure the logo takes up a quarter of your browser window. of course, this means that the content will be pushed down the page a little. don't worry, content isn't that important and people will find it if they really want to.

and again, if you can animate or make your logo 3D, that will increase its impact even more.
