Pubmatic posts average eCPM.

I found this table on Pubmatic to be fascinating:
http://pubmatic.com/adpriceindex/index.html
It lists average eCPM based on size of your site.
I think it brings it down to earth after hearing about people bragging that their 20 sites are making them $250/day each. It’s nice to know what can be reasonable expected.
