Ask IH: What analytics stats are essential for you?

Hey all,

Could you list the most important stats that you care about in your web analytics tool?

I ask because I'm building a web analytics tool for indie makers and bloggers. Currently I've implemented:

• Monthly/daily visitors
• Traffic sources (referrers)
• Top pages
• Visitor countries
• Screen sizes
• Browsers
• Operating systems

What else do you consider essential analytics data? What am I missing?
