Calculate CPC as spend divided by the selected click count, and specify whether that means all clicks or outbound clicks.
Inspect the components and the visit
A hypothetical EUR 600 spend and 400 outbound clicks equals EUR 1.50 per outbound click. It is arithmetic, not a target. Compare CPM and the corresponding CTR, then examine the landing page and purchase data. Cheap clicks do not establish revenue.
Write a focused creative hypothesis
Check changes in audience, offer, placement and season before attributing a difference to production. A clearer product demonstration or more explicit offer may be worth testing. Agree the test with your media buyer and preserve the variant identity. See image selection and click rate.
