ok so i put my adsense code on a new site over a week ago, and when i click on the "advertise on this site" link, it displays the domain i signed up with, not the new domain the ad is on

according to the adsense help i don't have to add a new domain or anything, they automatically detect it

so my question is....... How do i make it display the site URL that the ads are on? Or do i just have to wait for google to index my site again?
