google_ad_client="pub-xxxxxxxxxxxxxxxx"; google_ad_host="pub-xxxxxxxxxxxxxxxxxxx"; Is this normal for blogspot websites?
i do not understand the question - you mean the ids are different.Yes.they got to be.Or do you mean the digits are higher in the case of host id?If so,there is nothing to odd about that too.
you can check the revenue shear in your AdSense account hosts with access you can see there is 0% revenue sheared by blogger , so don’t worry and just have fun and be patience with time ,as the visits of your site will increase so the revenue of your Adsense. i have faced same problem
