Wow, its must betting good geo quality and very targetted/contextuel hits if you pay some bills with 1300
We push a lot of different products, around 50 different sponsors per day (some of ours), but most are only co-brand/white label or custom landing page (like freecamsexposed.com)
We average 5-10 millions hits per day in July... it pays some bills too
Different traffic generation but mostly its from ads the we bought and affiliate traffic
This automn we plan to reach the 10-20m hits bracket daily
