Google likes sites that their searchers like, presumably indicated by such metrics as pageviews/visitor, time on site, bounce rates etc.
So I think it is important to discuss what we can do to make our visitors explore more of our site.
For example Wikipedia's embedded links throughout each page, make it very easy to click on certain related subjects, thus increasing their pageviews.
What other factors have you noticed that increase your visitor interaction?
