A company has expressed interest in advertising on my friend and I's site and they asked to make sure that specific regions are hit, in this case specific cities in the US (SF, LA, DC, and a few others). Is there any sort of software that can be bought that can deliver a different ad targeted to someone in one of these cities, and say, a different ad yet again for visitors from New York, Texas, and Florida for example? Can you get that specific with scripting and such?
We started this site as a Frontpage site for fun in our spare time, we'd never imagined we would start to have to consider this stuff...not that I'm complaining mind you. :)
