To follow this through:

50,000 impressions bought at 25 = 1250

At CTR of 2%..
Total number of clicks = 1000
Cost per click = 1.25

At 30% conversion to sales, cost per sale = 4.17

But 30% conversion to sales? Is this the sort of performance you can
deliver to your clients or was the figure just there for illustration

I would have thought even 3% conversion to sales a bit on the optimistic
side, making the cost per sale in this example 41.70. At this rate lets
hope the merchant gets a repeat or multiple order through. And if the
conversion rate drops to 1% on a CTR of 2% and 25 CPM you have taken
the cost of acquiring a single customer above the 100 mark. Worth it?
