Ask HN: Users vs PageViews - What's more important

If pageviews are consistently high, but registered users are not, is that bad? How much does it matter?

I know user data is good, but is it critical for investors? I want to understand what's critical and why.

Can someone suggest the most important/relevant stats of the following?

Registered Users, Visits, Pageviews, Pages/visit, Avg. Time on site, New Visitors.

Thanks!
