A business owner doesn’t need forty metrics. You need to know whether marketing brought in customers, what each one cost, and whether the money made exceeded the money spent. Six numbers answer that completely — everything else is detail for the people doing the work, not for the person paying for it.
This guide names the six, shows where each comes from, and gives the owner’s question each should provoke. It pairs naturally with how to read and challenge an agency report and the GA4 owner\u2019s tour — this one tells you what to look at; those tell you where.
And if your current reporting can’t produce these six numbers, that’s the real finding: the measurement layer needs fixing before any channel — SEO, ads, or email — can be judged fairly.

The SixThe Six Numbers, in the Order They Flow
The six follow the money through your funnel — from attention to revenue. Read them in order and you can locate any problem in minutes:
| # | Number | What it tells you | Where it lives |
|---|---|---|---|
| 1 | Leads / enquiries this month | Is marketing producing raw demand? | Form + call tracking, CRM |
| 2 | Cost per lead (CPL) | What does each enquiry cost, per channel? | Spend ÷ leads, per channel |
| 3 | Lead → customer conversion rate | Is the website (and sales follow-up) converting demand? | CRM, analytics events |
| 4 | Cost per customer (CAC) | The true price of growth | Spend ÷ new customers |
| 5 | Revenue by channel | Which channels make money, not just leads | CRM + attribution |
| 6 | Marketing ROI | Did the whole programme pay? | (Revenue − spend) ÷ spend |
Numbers 1–2 measure the top of the funnel (are channels working?). Number 3 measures the middle (is the website converting?). Numbers 4–6 measure the business outcome. When ROI dips, walk back up the chain until you find the number that moved — that’s where the problem lives.
The FlowHow the Six Connect

From spend to ROI — an illustrative month
Notice what’s absent: impressions, sessions, followers, bounce rate. Those are diagnostic inputs for practitioners — useful when debugging an underperforming channel — but they don’t belong in the owner’s six because none of them is money.
The QuestionsThe Question Each Number Should Trigger
- Leads down? Ask which channel dropped — a single-channel dip is a channel problem; an across-the-board dip is seasonal or market-wide.
- CPL up? Ask whether spend rose or leads fell, and in which channel — then ask the channel owner the five paid-ads questions.
- Conversion rate down? The website or follow-up broke — check forms, speed, and the common leaks before blaming traffic quality.
- CAC up while CPL is flat? Leads are converting worse — a lead-quality or sales-process question, not a marketing-volume one.
- Revenue concentrated in one channel? Ask what happens if that channel’s costs double — concentration is fragility.
- ROI positive but falling? Ask for the trend by channel — mature channels plateau; the question is where the next pound works hardest.
Vanity MetricsWhat These Six Replace
| Vanity metric | Why it flatters | The six-number replacement |
|---|---|---|
| Impressions / reach | Big numbers, zero commitment | Leads (number 1) |
| Followers / likes | Audience ≠ customers | Revenue by channel (number 5) |
| Website sessions | Traffic without conversion is cost | Lead conversion rate (number 3) |
| Email opens | Inflated by privacy tech — see the email metrics guide | Revenue by channel (number 5) |
| Keyword rankings alone | Position ≠ enquiries | Leads + CPL from organic (numbers 1–2) |
None of these is useless — practitioners watch them daily as early-warning signals. They’re just not owner numbers, because no bank accepts impressions.
How We WorkHow Fredeveloper Reports the Six
Every Fredeveloper retainer reports these six numbers on page one, every month, before any channel detail — because that’s the page an owner actually reads. Behind it sits the tracking setup that makes them trustworthy: conversion events, call tracking, and CRM connection. The free quote includes a reporting review: we’ll tell you which of the six your current setup can and can’t produce — useful even if you never hire us.
FAQFrequently Asked Questions
Do I really only need six numbers?
As an owner, for a monthly decision-making review — yes. The people running each channel need far more, daily. The mistake is showing the owner the practitioner dashboard and calling it a report.
My business has long sales cycles. Do the six still work?
Yes, with patience: pair this month’s spend with the customers it eventually produces, not the customers who happened to close this month. A rolling three- or six-month view smooths the lag.
Where does profit fit — should ROI use revenue or margin?
Margin, ideally. Revenue ROI is easier to compute and fine for trend-watching, but the honest version subtracts cost of goods. Pick one definition and never change it mid-year.
What if my agency can’t produce these numbers?
First check it’s a tracking gap, not evasion — the report-reading guide covers how to tell. A good agency will say “we can’t measure number 5 yet, here’s the plan to fix it.” A poor one will offer impressions instead.
How do I count leads that arrive by phone?
Call tracking — a forwarding number per channel, reported alongside form fills. Without it, phone-heavy businesses undercount marketing results badly, which is part of any decent measurement setup.
Should the six be compared month-on-month or year-on-year?
Both: month-on-month for spotting changes fast, year-on-year for seasonality. A roofer’s January always looks bad against October — only last January tells the truth.
