In the game of direct response, there are only 2 variables:
- The amount of people you can get to see your message
- The percentage of people that buy after seeing your message

I agree that's important, but I still believe that the percentage of people who buy after seeing your message is useful only as a relative comparison.
For example, if I get 5% to buy as my control, and then I beat that control by getting 9% to buy, that's a useful comparison stat. But the 9% by itself is useless unless compared against 5%. I could get 9% to buy and still lose money. Then it's a losing ad, whether it's the market, offer, the copy, or any combination that's the culprit.
But if you say I have a ROI of 725% from a market/offer/ad, then you know I am making money with it from that stat alone. There's no need to compare it with another piece's results.
I'll take it a step further.
What if split test "A" gives a 5% response, that is 5% buy. And split test "B" gives a 9% response. Comparing the two would indicate that split test "B" wins, right?
But if you measure your lifetime customer value, you may find that split test "A" yields a better ROI in the long run than split test "B", when you factor in back-end offers and such. All things being equal, that's unlikely to happen unless the offer differs between the two split tests. But it's just a point to illustrate the kind of thinking that needs to go into testing.
Too many people just split test the front-end offer. If I'm split testing price (which usually goes to the offer, not the copy...unless you change the copy to support the price change, then it's the offer and copy that changes, but I digress), I may find out that I sell less with a higher price point on the front-end, but my back-end sales increase as a result, ultimately giving me a higher lifetime ROI. In fact, some sellers purposely set the initial price higher to weed out the tire-kickers. They've got their sights on the back-end sales.
Others purposely set their front-end price lower, because they want to build their list more. It all depends on your marketing plan, and ROI plays a huge factor in determining whether it's successful or not.
It really doesn't need to be that complex. ROI is a good measurement for any business plan or marketing plan.
Just my take on the subject.
