The issue with visits is what should you do with someone who clicks on a
link off your site (say an ad) but then comes back within a few minutes to
continue browsing through your content? With referers only, this would be
two visits. The timeout is used to try to capture the experience - a quick
side jaunt off a site but then back is considered part of the same session.
Most visit definitions use referers (and cookies and other means) to
identify a session. If there is no activity from that idenitifed person for
30 minutes, the next time they are seen it is counted as a new session.
