Interesting question, I always put internal links on my page and a small site map above all my articles so my visitors always know where they are and they don't leave my site after viewing just one page.

Well for example, you start off with one banner ad on your page and 9 internal links; you have a 10% chance of an ad click in link terms however if the visitor clicks another internal link and goes to another page you've increased the percentage to 20% and so on.

A lot of my pages are in sections like a book so they follow on from one another so I just put a text link to my next article leading on from the current under 'next'
