When you sign up for AdSense we ask you to tell us the URL of
the primary website that you want to show ads on. To successfully submit your
AdSense application, the URL that you provide must be a domain that you own,
and must not be a webpage or directory, or contain any parameters. For example,
if you’re the domain owner of example.com and
that’s the domain that you want to monetize with AdSense, then you should enter example.com in the box labelled “I will show ads
on.”
You will need to show ads on your domain, for your application
to be reviewed. The number of accounts that can use the same domain to sign up
for AdSense is limited. If there are already ads from a different AdSense
account being served on your sign-up domain, you'll need to use a different
domain to sign up for your new AdSense account.
