Assumptions & limits
CTR describes the counters you supply. It does not remove invalid clicks, align attribution, or measure visits after a redirect. Do not combine clicks from one platform with impressions from another without reconciling their definitions.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.
