I always relish a good data nugget sandwich like the
MocoNews post from a couple of weeks ago about how difficult it is to measure the size and reach of the 6 biggest US mobile advertising networks. The article highlighted some recent monthly unique site visitor data, per network, from Nielsen. Ostensibly the data indicates that
Millennial's network is the biggest (by a wide margin) in the US, with the
potential to reach up to 82% of the 55mil US mobile web users (
hmm...that's if they ever use their mobile browsers, right?).
Moco and an associated
post on Mobile Marketer spend a lot of time debating the value of these numbers as a method of comparison. Interesting, if you're into that sort of thing...but frankly what I really care about, and I know you do too, is figuring out how much money these guys make. Analysts, pundits and
panelistas love to throw out big mobile ad numbers like $2.7
bil WW and $300mil in the US...but I'm generally super-cynical about accepting that kinda nonsense at face value. So, despite the aforementioned measurement difficulties & the advice of school
marms everywhere, I decided to take a stab at the revenues the big 6 US mobile ad networks are seeing from selling ads on those networks.
So here are my assumptions... and, frankly, I think I'm being generous. I'm gonna say that the average US mobile browser is exposed to about 20 ads per month across these networks, which would be a total of 1.1bil impressions (55mil x 20) total. The reality, of course, is that this is a Pareto principle on steroids...wherein most of the activity is generated by a very small base. I've divided that number by the share each network has of unique visits (yielding about 6.4 impressions per network per month). Fantasy (rate card) mobile CPMs are $15 (good luck), but the blended reality (effective CPM) considering CPC deals, unsold inventory & a large remnant market is probably more like $1.75 (I know...ouch). Publishers keep about 60% of ad revenue (maybe more) and carriers (when involved) can take 50% before publisher...so I'm guessing that on average the networks keep something like 25% of their topline revenues. If these assumptions are correct...or even close to it (and my model isn't broken)...then, as you can see, these companies still have pretty nascent businesses.

btw -- this is a guesstimate (based on lots of assumptions...though, I believe, generous ones), so if anyone has any data points that could yield a more accurate outcome please feel free to comment (or contact me directly) and I'll make the appropriate modifications.
