>an online music cd store. wouldnt you want to have an "entry page" for different types of music (ie. country, rock and roll, jazz etc.)?
Yes. In that case your index.htm page would probably be a generic "welcome" page with links to each of the pages devited to a certain musical style. Those pages would have individualized meta tags, their own content, and links to any of their related information pages. These aren't "feeder pages" - a feeder or doorway page exists only to direct traffic to the real target and fool robots, with no useful content. On a multi-topic site, any 2nd-level page with a lot of specific content will soon be getting more traffic directly to it than the generic main page.
