Do Adsense ads adjust by city/country of IP address?

Do Adsense content ads take the city and country of the person's IP address into consideration? Or do I need to put this in with a channel or keywords?

I have a few real estate pages, and am going to put Adsense on each one, just wondering if the ads will automatically adjust based on the person's location or what I would need to do.

Thank you.

 

it's all automated just get some trafffic!

 

ok thanks they make it easy

Will it work for anywhere in the world-----so if I have the same real estate site and someone visits from New York and another from London, local ads will come up?

 

Quick answer, yes most likely they will.
They'll not if there are no ads related from where you live.

 

yes google gives this features to their advertisers , so that they can geographically target their customers .

 

I know I see local ads from Australia when I search or go onto a website displaying google ads.

 

Yes. Advertisers can choose the geographic location for their ads to appear. This is an extension of "contextual" advertising and is good for all. Google would be able to know the location of the visitor though their I.P.

 

^yup to what meteorite said. google will also know if you're using proxy hehe

 

Also the CPC is vary between countries, you'll get high CPC by getting clicks from US, UK visitors and low on other countries..
