My website is designed around a phrase that is mainly used in the uk, in the uk the bids mgiht be as high as 3-4 GBP however everywhere else the maximum is 0.7 $ so i wonder how i can structure my page so that the uk adsense adverts appear not the us? THANX
You cant - Google will serve the most appropriate advert based on the user's IP address automatically.
Cellularnews is correct. I'd suggest thinking about how to get targeted traffic from the UK in that case. A .co.uk domain wouldn't hurt either if it's appropriate, but the main thing would be getting listed or advertising on UK-centric sites
