$0.50 CPC
50 clicks $0.50 x 50 = $25 overall cost
Cost per mile/ Cost per thousand impressions (CPM)
𝐶𝑃𝑀 = 𝐶𝑃𝐼 𝑥 1000
=
𝑂𝑣𝑒𝑟𝑎𝑙𝑙 𝐶𝑜𝑠/ 𝑁𝑜 𝑜𝑓 𝐼𝑚𝑝𝑟𝑒𝑠𝑠𝑖𝑜𝑛 x 1000
Example
1
$2 is the CPM – but what’s the overall cost?
– Ad shown 10,000 times = impressions
– Overall cost = (CPM * Number of Impressions) / 1000
– $20 Overall cost
= 2 x 10000 / 1000= = $20
Cost per Acquisition (CPA)
CPA
– CPA = $10
– Advertiser pays website $10 every time ad leads to a purchase
– The ad led to 6 acquisitions
过程
𝐶𝑃𝐴 = 𝑂𝑣𝑒𝑟𝑎𝑙𝑙 𝐶𝑜𝑠𝑡 / 𝑁𝑜 𝑜𝑓 𝐴𝑐𝑞𝑢𝑖𝑠𝑖𝑡𝑖𝑜𝑛
Overall cost = CPA

6=$60
Click through rate (CTR)
The proportion of visitors to a webpage who click on a link to a particular site
– 50 out of 10,000 site visitors (impressions) click on an ad
– 50 / 10,000 = 0.005 multiply with 100 to get percentage:
– 0.5%
Might not always be accurate or useful for the advertiser → Clickbait etc…
