Lets say I have site1 and site2. Ok, now just out of curiosity I clicked on the "Advertise on this site" however when it takes me to the next screen in big bold letters it says "Advertise on <url for site1>" instead of site2. How do I correct such a thing? Also note that I've placed the adsense code on site2 about a week and a half ago, I'm thinking it takes some time for adsense to recognize the new site, am I correct?
The Advertise on this site link shows the information for the site you signed up for with Adsense. You should edit that in your Adsense account properties. Just leave it blank and it should show the site URL of the site where the visitor clicked on the advertise link.
yes, your right it takes a few days for adsense to recognize the new site. It should take a week and a half though, hmmm..........
No need to replace codes. If you change options in your CP for your account, all the work is done on Adsense's end. This included.
