Ask HN: I own a 2M pageview/month website, am I capitalizing on this?

I own a website that has 2M page views a month on 275k uniques. Right now my monthly revenue is ~$8000 USD, of which half comes from ads. To be honest the website looks like it came out of 1999 and I haven't investigated too much into other revenue streams.<p>I'm wondering whether I should invest time and money into improving the user experience, SEO, advertising deals, and other revenue streams. I know this is a very ambiguous description of my situation but I am hoping that others who manage similar sized websites can comment on their revenues.<p>My main question is whether I am generating a decent amount of ad revenue for that amount of traffic. The average user spends 10 minutes on the site.<p>Thanks!
