What is the difference between CPM and CPC?

CPM (Cost Per Mille) is the cost for one thousand views or impressions of an advertisement. CPC (Cost Per Click) is the actual price paid for each literal click on your ad.

How do I calculate CTR?

Click-Through Rate (CTR) is calculated by dividing the total number of clicks by the total number of impressions, then multiplying by 100 to get a percentage.
