Nate Silver of Five Thirty Eight has an amazing article on how much ad revenue a blog posts generates on Huffington Post.
"Do the multiplication, and you find that the average blog post — which we estimate generated a couple thousand page views — was worth about $13 in advertising revenue. The median blog post, with several hundred views, was worth only $3 or $4. Even Mr. Reich’s strongly-performing post was worth only about $170, by our estimates."
