I've had a good look around but can't really find anything but robots.txt and I still don't really understand that.

QUESTION:

Considering search engines don't like pages with no content, how do I go about getting various pages on my site that just have links to other pages spidered but not indexed themselves. E.g.

My index page has a link to the articles page, then that just links to several categories of articles.

Or doesn't this matter anyway?

Also a quick question about H tags
are they used for splitting up content on a page so the SE knows what each bit is about or are you supposed to put your keyword in the tag to emphasize your keywords?
