In brief: CPC (Cost per click) is the cost paid or calculated for one advertising click.
How I use CPC in practice
I compare CPC within a defined campaign, audience, placement and period, then connect it with landing-page quality, enquiries, sales and margin. A cheap click is useful only when it contributes to the business goal.
What to watch for
CPC does not measure intent, quality or profit. Automated optimisation can lower the price while attracting the wrong visitors or counting invalid activity.
Questions for a decision
- What exactly counts as a click?
- Which audience and placement produced it?
- What happens after the click?
- What is the cost per qualified outcome?
