I buy a site, on it already hangs adsense, I wish to leave it, but the account adsense at me is not present - it to itself I shall open. At registration I shall enter this site which I shall buy. For this time when I shall be registered - to clean adsense the old owner or it is possible to leave (and when to me will register - I shall put the)?
Yea, your English is not that good there friend. But if your saying that you want to put up adsense ads on your site that already has ads from another adsense account, then you cant. And theres a limit of 3 per type of ad anyway, so it doesnt make sense to have so many ads on your site.
If you bought that site from him, you can remove his Ads and put your on. If you don't have Adsense account, open one for free. but You can't have two Ads from 2 Adsense accounts display the sametime on the same page.
You can remove the Google Adsense ID from the Ex-owner and put your Public-ID into the adsense code, what you have gotten from Google.
The poster is asking if he is allowed to register with someone's else website, in a good will that he will buy it and switch to his code then. To tell you the truth, I don't know what happens when someone register's with someone's else website. Peace,
