Halving cost per lead by changing what counted as a lead

The growth team spent against a definition of a qualified lead that did not match what converted. Rebuilding the measurement cut marketing spend per lead by half.

The situation

Corporate development at PINTAR was asked to make growth spending more efficient. Cost per lead was the number on the slide, and the obvious response was to spend less.

The number was also the one nobody could defend. The definition of a qualified lead had drifted away from the leads that actually enrolled, so the team was optimising a metric that no longer described the business.

Rebuilding the definition

I went back to enrolment data and worked out which lead attributes predicted a student who finished registration, rather than one who filled in a form and left.

Then I rebuilt how corporate development measured lead quality, and the growth team began spending against the new definition. Marketing spend per lead fell by 50% within the year, and the saving was not only arithmetic: it changed what the team was allowed to spend against.

One set of numbers

People, Product, Engineering and Finance each reported their own version of the same period. I consolidated reporting across the four teams so leadership argued from one set of numbers.

That is the least glamorous work in analytics and the most useful. When the argument is about whose number is right, nobody is discussing the business.

Moving the work forward

When an initiative stalled, I sat with the Head of Growth, worked out what was actually stuck, and then executed the fix rather than handing over a recommendation. A slide that says someone should do something is not analysis. It is a note.

I also mentored three interns from SQL basics to shipping a dashboard on their own. None of them started with a template to copy, which is why the ones who finished could do it again.

What I would do differently

I would document the lead definition the day it was agreed, with the queries attached to it. Definitions drift because they live in slides, and a slide cannot be tested.

What this proves

Measurement is a business decision before it is a technical one. When someone says cost per lead is too high, the first question is what counts as a lead, and I have changed that answer in a way that held up for a year.
