The Metric Your Agency Reports Is Probably the Wrong One

April 15, 2026 · 5 min

Every monthly report we have seen from a competing agency leads with cost per lead. There is a reason for that, and it is not that cost per lead is the most useful number.

It is that cost per lead is the number an agency can improve without doing anything difficult.

How to halve cost per lead without helping anyone

Remove the qualifying questions from the lead form. Cost per lead drops immediately, often dramatically, because completing the form got easier and more people finish it.

Nothing about the recruiting improved. The carrier now receives twice as many applications, of which a larger share are unqualified, and the recruiter spends their week on calls that go nowhere. But the report shows a number that halved, and the report is what gets discussed on the call.

Broaden the targeting. Switch the optimisation event from application to landing page view. Run the ads in markets where labour is cheaper regardless of whether you can hire there. All of these improve cost per lead. None improve the business.

What to ask for instead

Cost per qualified application. How many applicants met the basic requirements — right CDL class, sufficient verifiable experience, clean enough record to pass.

Cost per hire. Total spend divided by drivers who actually started.

Ninety-day retention by source. Of the drivers hired from each campaign, how many were still there three months later.

That last one is the number almost nobody tracks, and it is the one that exposes whether a campaign is attracting drivers who fit the operation or simply drivers who will accept anything.

Making it possible to track

None of this works without connecting the advertising data to the hiring data. Practically, that means a source field on every application that survives all the way through to the hiring record.

It does not need software. A column in a spreadsheet, filled in consistently, is enough. What it needs is that somebody does it every time, because a source field completed sixty percent of the time produces conclusions worse than no data at all.

The conversation worth having

Ask whoever runs your ads what your cost per hire was last quarter. If they cannot answer, they are optimising toward a number that does not pay your bills.

That is not necessarily bad faith. Plenty of agencies have never been asked and so have never built the tracking. But it is the question that separates the ones producing drivers from the ones producing reports.
