sub.site.com and www.sub.site.com .. why is it diff for AS?

happening in a new subdomain

[caspita]

Hi,

I'm creating a new subdomain for a new service on my website .. I have some pages ready and I have put the AS code on them to see the Ads are going to appear .. but is happening that when I load the pages using subdomain.website.com I'm able to see good tageted ads, but when I use www.subdomain.website.com all what I get is PSA.

Why is it happening? is there something I can do to avoid this? or just the time will fix it?

Thanks.

Now that I can play with both ways I can say that it look to work much better using www.subd.website.com :-)

AdSense considers each to be different URLs. It would do the same with example.com and www.example.com
