The new AdMob Mobile Metrics Report for November is out and it has some interesting metrics in it, especially because it looks at the trends of the past year 2009. It is always a little biased in that it only takes AdMob’s own publisher network into account, but the scale of their network gives the report more than just a little representability.

Some of the major developments were the increase of smartphones regarding share of mobile web and app traffic (up 48% from 30% last year) and the tripled amount of requests via Wifi. Another interesting fact is that traffic regarding Android devices seems to spread almost equally between different devices as they keep adding to the number of Android devices in the market. In our opinion this substantiates the assumption that not one Android device will be able to compete with the iPhone, but rather a whole array of different handsets that will enter the market.

What’s most interesting about it is how the amount of iPhone and iPod touch users is divided between countries and how this has developed throughout the last year. 50% of all iPhone and iPod touch users in the AdMob network now come from the U.S., while the other half seems to have evolved into a “country long-tail”, with the U.K. at 8%, France at 6% and Germany as well as Canada at 4% (17% are made up by countries with a share below 1%). Especially Japan, France, Australia, China and Germany have seen a massive user growth, with Japan at more than 300% increase and the others mentioned close to 300% or above 200%. And (we think) we are only at the beginning of the mobile “revolution”. Great times ahead – Android will probably take a similar route in terms of distribuion by country.

Find the entire report here – it’s well worth your while, we think. As weekend reading you should also take a look at the Morgan Stanley “Mobile Internet Report” though for this one, you should really bring some time.
