Search advertisers have always valued the way Google AdWords lets you target specific geographic regions. For example, if you install stereo systems in the Chicagoland area, why would you want someone in California to see your ads? It’s just a waste of your advertising budget. So, AdWords would let you specify campaigns, within an X-mile range of your nearest metropolitan city.
Now, you can also target or exclude specific physical user locations by ANY city. And it’s getting better, and getting more granular. Think about the possibilities of targeting customers with your restaurant ad. But only those who type in “restaurant” within 1/4 mile radius of your location on their mobile device.
That’s the future. And Google AdWords is “this close” to having us there.
