What is CPC? Cost per click explained

CPC (cost per click) is the average amount paid for each click on an ad.

How is CPC calculated?

CPC = ad spend ÷ clicks

Example

$600 of spend for 1,200 clicks is a CPC of $0.50.

Why does CPC matter for e-commerce?

CPC is set by the auction on search platforms and by CPM and CTR together on social platforms. Lower CPC only helps if those clicks still convert.
