Questions
What does CPM stand for?
Cost per mille: the cost of 1,000 impressions. CPM = cost ÷ impressions × 1,000.
How is CTR worked out?
Clicks ÷ impressions. 2,000 clicks from 100,000 impressions is 2%.
What if there were no clicks?
CPC can't be calculated without clicks, so it shows a dash. CPM and CTR still work.
