Social Networking CPMs
Now that News Corp is by and large disclosing MySpace’s revenue figures on a quarterly basis we can see whether CPMs are going up or down.
How? By comparing revenue growth with usage. Revenue = usage * CPM.
First revenue: “meaning that FIM’s non-search dollars increased 43% y/y”
Now usage: It looks like comScore thinks that MySpace’s worldwide UV in the fourth quarter was around 100m uniques per month, up from around 80m uniques per month in the corresponding period a year ago.
So if that is 25% UV growth, and 43% revenue growth, that means CPMs went up by 14%.
Conclusion CPMs are going up but not by much and not by the factors they need to be for them to be great businesses instead of very good ones.

For CPMs, wouldn’t you look at pageviews rather than unique visitors?

Henrik, true enough but they re-load ads based upon time now that ajax is a bigger part of the site.
