you're getting 60p for every click
Each click have a different bid price, so the CPC is not telling you that EACH click are billed 60p.
CPC = Earning / number of clicks
That's all.
So let's say you have 4 clicks:
- one click with a bid of 10p,
- a second click with a bid of 5p,
- a third with a big of 30p,
- and a fourth click of 15p.
It makes a earning of 60p and 4 clicks. So the CPC is 15p, but it doesn't mean that each click had a bid of 15p.
So in the middle, if you have 5th click with a bid of £2, this is pulling the CPC up. In that case, your earning will be £ 2.6 and your CPC at 52p
Now, the thing is, the earning also includes CPM, so if you have no more clicks after these 4, your CPC will continue to evolve as CPM earnings will be added (or removed)
So let's take another example,
- one click at 10p
- £1 earned with CPM
the total earning is £ 1.10 , so with one click, the CPC will be £ 1.10 where as the click itself was only 10p
