CPC (cost per click)

CPC is total spend divided by the number of clicks. On Google Search you can also set a maximum CPC, the most you are willing to pay for a click; the actual CPC is often lower, because it depends on the auction.

Example: 450 SAR of spend and 300 clicks give a CPC of 1.5 SAR. CPC connects to CPM and CTR: with a 5 SAR CPM and a 1% CTR, each click costs about 0.5 SAR.
