The same way you (probably) do on your “normal” website: Google Analytics.

Your mobile website is – in some fundamental sense – just another website and thus can support Google Analytics. You should probably create a new “website profile” on Google to ensure your mobile site analytics are independently tracked. Note that a few older mobile phones – especially BlackBerries – don’t have JavaScript turned on and thus won’t be reported in your results. So it goes.

For your apps, Google provides Google Analytics for Mobile. The reporting in mobile analytics is radically different from website reporting, being based on “events” which are essentially “stuff the user did in the application” – looking at the events calendar, looking at a particular listing, dialing a number (from within your app), etc..

Note that ongoing disputes between Apple and Google may mean use of mobile analytics may be curtailed at some point in the future – or it may not be.

There are other mobile analytics packages available, though at this point we have heard no compelling reasons for learning a new reporting system. Please send us an email if you’ve had a different experience.
