I used to pay $100 a month for another service which has roughly the same value proposition (not naming it to avoid shilling), and paid for it in perpetuity by five words of microcopy it caused me to add to my purchasing page. Everything after that was gravy. I don't want to imply that five words doubled my conversions -- nothing close. It is just that a move-the-needle effect anywhere in a business where all factors are multiplicative achieves $100 so fast your head will spin. For those of you whose firms could lose my business in the petty cash drawer, changes so small I'm unable to even construct tests with sufficient precision to detect them will generate more than $100 a month.
