Resolution
For example, if there are 10000 (hits) for WT.ad=Frogs and 1000 (hits) for WT.ac=Frogs the Onsite Ad Clickthrough Rates report will be populated. However, if the site for any given day has 10000 (hits) with WT.ad=Homepage Banners and no (hits) for WT.ac=Homepage Banners the Onsite Ad Clickthrough rate metric will be blank.
