Contrary to common belief, CPM rates are determined based on your channel's content, not the network you are partnered with. Every network uses the exact same advertising system, the one provided by YouTube. No network has a "special" deal to guarantee any CPM rate, as it fluctuates periodically.
With that in mind, here are Freedom!'s average CPM rates for June 2014.
Partners averaged $12.18 CPM ($7.67 RPM) on a 60% revenue share across the entire network in the UK.
Partners averaged $11.02 CPM ($6.35 RPM) on a 60% revenue share across the entire network in the US.
