I think it depends on the kind of web-site you are running more than anything as to which metrics are important. Just like in finance, depending on the business model, different metrics are tracked (e.g. free cash flow, revenue, etc.). Plus, hardly ever is a single metric important. Sites will look at page views for new/existing visitors, bounce rates for new visitors, time on site, etc. depending on their goals.
What this tells you, though, is that if they are only seeing 1.1 million unique visitors a month that those visitors account for 1,000 page views a month which is a lot. And that's the average! I bet a lot of sites would love to have that number.
