Depends on how lucrative your users are to advertisers. <p>If your newsletter was read by 100 CEOs of Fortune 500 companies, I doubt you would have a hard time finding advertisers.<p>Social network "junk traffic" is not particularly valuable. You would need millions of page views just to get in the door of major media buyers.<p>Adsense is a different story - you don't need page views to get started.
So you've got 2500 unique visitors this month doing 50k page views. general, social network traffic might generate $1-2 cpm so that's $100/month in revenue. <p>if you have a high value niche with targeted, quantifiable traffic you can get that maybe as high as $50/cpm on a well marketed site (read: you have ad sales people or you're cramming the site with ad channels.)<p>This guy

has grown his blog to 250,000 page views, crammed it with every kind of contextual ad you can think of, is a compelling writer with great content. He's at $50/cpm. Of that, 40% comes from a pay-per-post ReviewMe ad thing, so his ads are generating about $30cpm. <p>So you can put adsense on the page, but you won't make any money. and you're a ways off from doing banner ads. <p>
Last month when my startup signed up our first groups we did about 25,000 page views, and this month we're on track to do about 50,000. My current average pages viewed per visitor ranges between 20 and 30, but what I don't know is how many page views does a website need to produce a month before it can get advertisers?
The larger questions are:<p>1) How targeted is my audience?
2) How well can I describe my audience?
3) How many ads do I need to sell to justify the costs associated with selling ads (ad server, cost/time of setting up the ad server, salesperson, etc)?<p>"Getting" advertisers is an active process (i.e. sales) for most publications (online and offline).
50k pageviews a month will not draw too much attention unless you are in a specific niche and someone notices you.<p>You can always throw up some google ads in the meantime. If you have good cpm/ctr numbers from google it will help.
I'd go with AdSense to start -- and/or maybe some others.<p>Does anyone know if Google cares if you run other networks' ads on the same page as AdSense ads? I think I've seen people do this.
