What it does
Many ad tests prove nothing. Two versions change three things at once, run in different weeks, or get called after a handful of replies. This prompt sets up the test before you spend. It finds the one difference between your versions, and if there are several, it splits them into separate tests. It picks a fair way to divide the audience and gives each version a key so you can tell the results apart later. It sizes the audience so you reach about 100 replies per version, and shows the sum. Last, it writes the winner rule, with a read date, before launch, so you cannot change the goalposts after.
