Thoroughness is not the same as clarity
Most agency reporting is built to survive a difficult meeting rather than to make a decision. If you present forty metrics, one of them is always up, and there is always a story available. That is not rigour. It is insurance.
The problem is that a client cannot act on forty numbers. They can act on one. So the first thing we agree on any account is which single number the work answers to, and we agree it before anything is built.
What the number usually is
For most ecommerce brands it is blended return: everything spent across every channel, against everything earned. Not platform reported return, which counts the same order three times, and not last click, which hands credit to whoever happened to be nearest the till.
Blended is unglamorous and hard to game, which is exactly why it works. When the number is blended, a channel cannot win by stealing credit from another channel. It can only win by growing the total.
What it changes day to day
It kills a lot of arguments. When retention wants budget and paid wants budget, there is no debate about whose dashboard is more flattering, because both are measured against the same total.
It also makes it obvious when we are wrong. If the number is not moving, no amount of channel level improvement counts as progress, and we say so rather than presenting the part that happened to go up.
