The idea in everyday life

Fictional Lantern Prints sells $50 posters. Its practice goal is completed paid orders, counted once by order ID during a seven-day window. An ad dashboard lists 30 checkout starts, 24 payment attempts and 20 unique completed orders.

The idea

Choose a completed customer action and a consistent counting rule before comparing channels.

Define a measurable marketing goal — worked practice

Choose a completed customer action and a consistent counting rule before comparing channels.

Fictional Lantern Prints sells $50 posters. Its practice goal is completed paid orders, counted once by order ID during a seven-day window. An ad dashboard lists 30 checkout starts, 24 payment attempts and 20 unique completed orders.

  1. 1. Choose outcome

    Use completed paid orders as the goal.

    You should see: Goal count is 20.

    Starting checkout is not completing payment.

  2. 2. Define denominator

    Use 500 recorded visits in the same week.

    You should see: Order conversion is 20/500 = 4%.

    Match numerator and denominator scope.

  3. 3. Name limitations

    Note that visits are not necessarily unique people.

    You should see: The metric is orders per visit.

    Do not call it a customer conversion probability.

  4. 4. Write measurement card

    Record goal, ID rule, period, denominator and owner.

    You should see: A repeatable definition fits on one card.

    Definitions prevent shifting success measures.

Now change one thing

There are 12 completed orders from 300 visits. Enter conversion percent without a percent sign.

Your work

What to finish
