7. You ran a split test of a control vs. a test package which involves only copy changes. In roll-out quantities the package promotion cost/M will be the same. The test beat the control by .5%. Applying the proper statistical test shows you can be only 80% certain the test result truly is better. Do you adopt the new package as your control?

8. Your business is able to acquire new customers at breakeven or better and has therefore adopted a rule to only roll-out efforts that exceed breakeven. You therefore believe there is no need to establish the long term value of a customer. Is this view correct?

1. ANSWER: 20,000/25 = $800/M. Sales/M alone will not tell us whether or not this is a good outcome. That will depend on many other factors including whether this was the result of a house or prospect effort, what we expected based on previous experience, hat medium was used, what the cost per buyer is if we lost money, etc.

2. ANSWER: $600/$40 = 15 orders per thousand to break even or a 1.5% response rate. With each order worth $100 in sales, breakeven sales/M = 15 * $100 or $1500/M. This can also be solved by dividing promotion cost by the contribution %: 600/(40/100) = 600/40% = $1500!

3. ANSWER: It depends on the customer’s lifetime value.

4. ANSWER: No. Since the widget brings in revenue, the correct way to calculate acquisition cost is to divide net profit (net sales less cost of goods, operating, overhead and promotion costs) by the number of buyers acquired.

5. ANSWER: ($1200 * .3) - $500 = ($140). Cost (loss) per buyer = ($140)/20 = -$7

6. ANSWER: Cost/lead = $2500/100 = $25. There is no way to know whether or not the ad is successful. It depends on the conversion rate of leads to sales.

7. ANSWER: It depends. If the control is relatively recent and hasn’t been used too often, the risk of changing is minimal. If it is well established and test quantities were small, you should probably retest the new package, but in larger quantities.

8. ANSWER: Not really. Though breaking even or better is admirable, by ignoring long term value you may be sub-optimizing business growth. Also, if response rates decline you will be unprepared for the day when a breakeven goal may no longer be sustainable.
