Questions
Which denominator does each metric use?
CPM is spend ÷ impressions × 1,000, CPC is spend ÷ clicks, CTR is clicks ÷ impressions, CPL is spend ÷ leads, CPA is spend ÷ conversions, conversion rate is conversions ÷ clicks and ROAS is revenue ÷ spend.
Why does a metric say it needs more input?
A metric is only calculated when both of its numbers are present and the divisor is above 0, so you never see a division-by-zero result. The tool also warns when clicks exceed impressions or conversions exceed clicks.
