Yes, this appears to have been changed in the course of this year. When I last did my tests, I couldn’t see city/town level geotargeted in a different country. Looks like Google have conflated several different types of geographical search into a single targeting mechanism, probably because it often satisfies an advertisers intent.

There are some “exclusionary” methods, also new, for geotargeting. I have not checked to see whether you can include the USA, and then exclude every state. Or for countries without State level targeting, whether you can select a larger area (e.g. Africa) and then deny all the countries there.

I’m expecting to restart the geotargeting tests in Q1 2009, so there’ll probably be an update on this by June 2009.

I don’t want my ads showing in USA, period!

This is not possible, read my post about this, which I call, “Geotargeting goes on Vacation”.

I’d be really interested to hear how you guys represent, for example, the location of mobile phones – because the location changes with time? What about users with dynamic IP addresses, e.g. low cost ADSL and dialup ISPs? I’ve got a lot of questions that aren’t well answered (or even addressed) by most geolocation companies, on their web sites :)

I suspect, from my small sample, that you can’t offer better than about 75% of IP addresses in the UK with a location more specific than “in the UK” – because of the way that the telco structure works here, and the frequency of use of dynamic IP addresses.
