There are lots of stats you can check
Monday August 25, 2008
There are lots of metrics you can track on a website. And while most metrics programs will track most, if not all, of the stats mentioned in this article, it can be hard to know which ones are most valuable to watch. Yes, it'd be nice to be able to look at all of them, but unless you have a full-time metrics analyst on your team, chances are you don't have the time. I know I don't.

I think one very important one that is not on the list is tracking traffic spikes for security purposes. We use these to identify and address potentially hackable or hacked pages and identify IP adresses that are attempting hacks. I noticed a spike once whose top referreer page was a site that hackers use to share potential exploits. As a result of using it for tracking spikes, we can find IP’s that need to be blocked and identify security weaknesses.
