CPM is a fairly standard unit of measure in the online advertising business.
It stands for **Cost per thousand** (the M is the Roman numeral for 1,000). What it’s measuring is the **cost per thousand [ad impressions] [ad-impression]**.
Take [heisel.org](http://heisel.org) for example. For the month of November I had a little more than 1,000 [page views] [page-view]. If I sold ads, and if I sold them at a $5 CPM, then I’d have roughly $5 in revenue for the month.
A simple number that belies even more to talk about, but I’ve got a tree to decorate, so that’s all for tonight.

By day, I'm a product manager serving a group of fantastic engineers at Square.
By night, I fight crime and solve mysteries with a robot pal of my own creation.
By midday, I like a snack, generally a cookie.
Part of this biography isn't true (hint, I like cookies and engineering, I don't own a robot)
