I have a blog that brings me about 2K Pageviews per day. I need a solid way to monetize it. The niche is "entertainment" and it already brings me 2-3 bucks every day through Adsense. I need some other way to monetize it. I have heard that the CPM is one good option to go with. I heard that Pop-unders have higher payouts but then I do not want to trouble my visitors with any pop ups. Are there any better ways (apart from Adsense & CPA - which I already have set up in my blog) to monetize this traffic?
